Sunshine, bugs, and volunteers

People enjoying nature!

We could not have asked for better spring weather for our 120 volunteers on April 18!  They soaked in the sun and warmth while visiting 50 different creek and river locations across the Huron River Watershed. Held twice a year, HRWC’s River Roundup is one of the most effective ways that HRWC has to understand how the water quality of the river and creeks may be changing. From the macroinvertebrates collected during this event, we are able to keep abreast of the health of our waterways throughout the watershed. You can see all the results in April 18 River Roundup Report.

Highlight

Mill Creek is the largest tributary to the Huron River, draining  143 square miles of land, 68 of which are agriculture. Agricultural impacts have certainly taken their toll on Mill Creek, with some Mill Creek’s tributaries no more than straightened ditches, and the creek has phosphorus and E.Coli issues that come from fertilizers and animals. However, great things are happening in Mill Creek, including the removal of Mill Pond Dam in Dexter, stream stabilization projects, landowner education, and a renewed interest in bringing residents to the waterfront.

As a part of the River Roundup, volunteers regularly visit 9 sites on Mill Creek (the main branch and several tributaries).  Four of these sample sites are showing significant improvements in the macroinvertebrate populations, indicating improving water quality and habitat.  These four sites are Shield Road (near the mouth), Manchester Road and Klinger Road (both in the headwaters), and Fletcher Road (on the north branch).

Shield Road in particular seems to be doing quite well with several highly diverse samples taken since the removal of the downstream dam.  The graph to the right shows the changes in the EPT (mayfly-stonefly-caddisfly) family diversity, with the red line in the middle of the graph indicating the dam removal. Samples in the early 2000′s were particularly poor with only 2 or 3 families found, and now we are regularly finding  6 or 7. Insect families that are now found which were not found previously include Baetid mayflies, Isonychia mayflies, Leptophlebia mayflies, and the Philopotamid caddisfly.

You can learn more about Mill Creek from our creekshed report.

South Ore Creek has fewer insects than we would expect despite areas of great habitat. When this happens, the likely culprit is some type of chemical pollutant.

South Ore Creek has fewer insects than we would expect despite areas of great habitat. When this happens, the likely culprit is some type of chemical pollutant.

If you have read these updates before, you will recall that we have learned that several streams in Livingston County have had significant reductions in their insect populations over time.  In fact, of the 62 sites that we monitor across the Huron River Watershed, 20 are in Livingston County, and 9 of those have statistically significant reductions. In contrast, HRWC monitors 30 sites in Washtenaw County and the insects at 12 sites are statistically improving while zero are declining.  Now, this may simply be a coincidence, as it is difficult to explain why a political boundary can make such a difference in insect populations.  But the data speaks pretty clearly; among others, Davis Creek (South Lyon area) has been declining, and South Ore Creek (Brighton area) is also getting worse.  Thankfully, both of these creeks could still be considered relatively healthy (when compared to more heavily urbanized creeks like Malletts), but we have to make some extra efforts to get these creeks to reverse their negative trends.

 

What’s next?

You should be a creekwalker! In this unique program, you will walk up and down a stream, exploring it and looking for possible pollution sources.  Join by yourself, with friends, or with your family.  Learn more about it at http://www.hrwc.org/volunteer/creekwalker/.

While it may not seem like it today, HRWC’s field season, and thus many volunteer opportunities, are right around the corner. Our first volunteer training (for our Water Quality program) is on March 21. River Roundup and Bioreserve training are sure signs that spring is imminent.

As many of our volunteers and supporters know, most HRWC programs are family friendly. It’s been a delight seeing many of our youth volunteers grow into thoughtful, giving, young professionals. Numerous studies have linked volunteering to being happier and healthier. So why not get your favorite kid involved in the community, especially HRWC? For some tips, see this Points of Light blog on getting kids into volunteering. To see if your youth is a good fit for one of our programs just ask the program lead!

If you’re interested in HRWC’s volunteer programming in general, Jason would love to hear from you: jfrenzel@hrwc.org.

Stoneflies! Cute AND educational!

Stonefly Search 2015 Wrap Up

A Surprisingly Pleasant January Day
So cute! Who wouldn't want to spend a cold Saturday in January looking for one of these?

So cute! Who wouldn’t want to spend a cold Saturday in January looking for one of these?

You never know what a Michigan January will bring; last year HRWC was forced to cancel the Stonefly Search because of sub-zero temperatures and blizzard conditions.  But this year, on January 17, 125 intrepid volunteers enjoyed bright sunshine and 30 degree weather as they spread across the Huron River watershed. They were in search of stoneflies, which are only found in clean and healthy streams.  Everyone made it back safe, and not a single leaky wader was reported! Overall, it was a great success!

The results are in, and are given in this pdf report.

What We Found

1. Usually when we look at the data after an aquatic bug search, we see that some sites do better than normal, some sites do worse, but most sites stay the same. This was a strange year because while most sites stayed the same, several did worse than normal, and none did better.  Overall, the count of stonefly families was down about 10% from our last sampling event (2013). There is no clear explanation for this; weather conditions were great and the ice wasn’t any thicker than other year.  We will start to be concerned if we continue to see this happen year after year. However, there is always natural variation in the data and collecting and this year will likely not be the start of a downward trend in terms of the overall sampling.

2. That being said, there are specific locations that have shown long-term degradation. For example, Honey Creek in Ann Arbor. The team searching for stoneflies in Honey Creek at Wagner were unable to find stoneflies. This site has been sampled 14 times since 1995, and this is the first time that stoneflies could not be found. This is a site with lots of turbulent highly oxygenated water and should be a great place for stoneflies. Taken in isolation, the absence of the stoneflies at Wagner Road would not be concerning given that this is a single sample.  However, two upstream Honey Creek Adopt-a-Stream sites used to have stoneflies but haven’t in years.  Stoneflies haven’t been seen in Honey Creek at Jackson Road since 2008; they haven’t been at Honey Creek at Pratt Road since 2003. All of the pieces combined indicates that the overall quality of Honey Creek is degrading over the last decade.

3. Davis Creek at Pontiac Trail is another location where the stonefly population has dropped over time. This change is concerning because it happened slowly over the last ten years and our spring and fall samples show a very similar pattern.  In the early 2000s we regularly found one or two stonefly families at the creek, but they started to drop off and now have not been found since 2009.

4. All this doom and gloom needs to be put in perspective, though. Remember, most of the sites we visited were as healthy as ever.  Of the 61 Adopt-a-Stream sites that HRWC uses to assess the overall water quality of the watershed, stoneflies are regularly found at 38 of them. In other words, 62% of our watershed has very high water quality and habitat. This agrees with recent analyses of other HRWC data, showing that 66% of the watershed was good to very high quality, 28% was fair to good, and 7% was highly impacted (2014 State of the Huron)

Next on the horizon!

Interested in doing more with our macroinvertebrate searches?  Think about becoming a trained leader or collector by coming to the next training on March 29.  This is an extremely important job because every team needs both a trained leader and collector, and we often do not have enough to meet the demand.  Sign up for the training!

It all comes down to this, the final visit.  This time, I arrived early so I could set some crayfish and minnow traps.  I had seen fish on earlier visits but could never get a good look at any of them.  The deepest part of the stream was where I placed the thermometer so I figured that would be a good site for a trap.  I also placed a crayfish trap further upstream in a rocky area hoping to catch some more crayfish and get a good positive ID.  Everything was set!

Creekwalkers look pick up trash, take water measurements, and record and photograph erosion and infrastructure problems.

As I walked back to my Jeep, Erin was heading down the trail.  After our “Hello’s” we headed back to the parking lot to get the rest of the gear.  We picked up the paperwork, meter, measuring stick and my camera and headed back to the stream.  Our starting point was where I placed my crayfish trap and we had 6 crayfish already in the trap.  As I started to pull them out for pictures I found that 3 of them were the invasive Rusty.  The other 3 were northern crayfish.  They were a lot bigger than the Rusty’s so I’m hoping they are holding their own against them.  Too bad; after our last trip I thought that there weren’t any Rusty’s in here.

In midsummer, Woods Creek is a great place to sit down and soak in the cool water... if the mosquitos aren't too bad.

In midsummer, Woods Creek is a great place to sit down and soak in the cool water… if the mosquitoes aren’t too bad.

We then started by taking the water temperature and conductivity readings. When we reached the halfway point I handed the GPS and water conductivity meter over to Erin.  She wanted to see how the meter worked and I needed to get some pictures of her as well.  She took about 4 more readings and then next thing we knew we were at the end of our sample area.  All that was left now was for Erin to compile all the data and for me to turn it in with all the equipment. Mission Accomplished!

I have to say the creekwalking experience was a lot of fun.  Walking up and down Wood Creek brought back a lot of fond memories of myself as a kid exploring all the creeks and streams of my youth.

Good times.

Rounding Up the River

River and creek sampling

Thanks to 108 volunteers who contributed a total of 643 volunteer hours, the 2014 River Roundup was a great success!  The weather was perfect for our volunteers as they split into 21 teams and traveled to 42 different creek and river locations across the Huron River Watershed to assess the aquatic benthic macroinvertebrate community.  This study is one of the most effective ways that HRWC has to keep its finger on the pulse of the stream. From the data collected at this semi-annual event, we get a better understanding of which creeks and rivers are getting better, which are getting worse, and how we can direct our management activities.

You can see all the results in April 2014 River Roundup Report.

Current Watershed Healthconditions April 2014

In a nutshell, the health of the watershed as judged by our macroinvertebrate sampling is holding steady. Of the 62 sites that we monitor to judge this, 28 sites have had no statistically significant changes over time, and 6 sites are too new to make this judgment.

Fourteen sites are declining, and these include locations on Chilson Creek, Davis Creek, east branch of Fleming Creek, Norton Creek, and South Ore Creek.  The majority of the declining sites are in Livingston County.  Eight of the declining sites are in Livingston, two are in Washtenaw, and three are in Oakland.

Fourteen sites are significantly improving.  Twelve of the improving sites are in Washtenaw County, including Boyden Creek, Horseshoe Creek, the main and west branches of Fleming Creek, Huron Creek, the Huron River in Ann Arbor and Ypsilanti, Malletts Creek, and several places on Mill Creek. One site is improving in Livingston County (Mann Creek at Van Amberg Road), and 1 site is improving in Wayne County (Woods Creek at the Lower Huron Metropark).

1. Malletts Creek is an urban creek in Ann Arbor that has been the focus of restoration efforts for well over a decade. Last fall, we noticed a more diverse insect community in Malletts Creek than had ever been seen before.  We are happy to report that this spring we once again saw a healthier insect community than ever before.  From 1993-2013, volunteers have found an average of 5 insect families in spring samples, but in 2014 volunteers found 9 insect families. One of these insect families is a finger-net caddisfly, which is common in healthy streams but has never been found in Malletts Creek until now. The increase in insect families over time is statistically significant.

Our congratulations go out to all of the partners involved in fixing Malletts Creek! An increase in the diversity of aquatic insects reflects an increase in the overall water quality, water stability, and habitat quality. This is a major accomplishment!

2. The volunteers who sampled in Boyden Creek along Delhi Road pulled in a bonanza of caddisflies! They found 5 different types of caddisflies: the common net-spinner (Hydropsychidae), the square barked case- maker (Lepidostomatidae), the northern caddisfly (Limnephilidae), the finger-net caddisfly (Philopotamidae), and the rock case-maker (Uenoidae).  They also found two families of stoneflies and two families of mayflies.  We have been seeing good changes in Boyden Creek for several years now, and this sample was one of the best taken this spring.

Lowlights

The volunteers who sampled at Greenock Creek near South Lyon were not impressed with the size and abundance of the leeches they pulled out of their trays, nor were they impressed with the total abundance and diversity of the overall insect community.  Greenock Creek was never a very healthy creek, but conditions have significantly worsened here since monitoring began in 1993.  The creek is located downstream of Nichwagh Lake, which is impounded by a dam.  Water exiting the lake and entering the creek is quite warm, regularly reaching 85 degrees Fahrenheit in the summer, which is too warm for many types of aquatic life. It is quite possible that dissolved oxygen levels are very low in the creek also (even in the non-summer months when the water is not as warm).  This is something that HRWC will look into.

Now that the initial visit and thermometer placement was out of the way it was time to schedule the second visit. Like our previous trip, real life issues came up for most of the team, and Erin and myself continued our team of two.

Mosquitos can be bad during a creekwalk, depending on the location and weather. Long pants and long sleeves may be a good idea! Right, Erin?

Mosquitos can be bad during a creekwalk, depending on the location and weather. Long pants and long sleeves may be a good idea! Right, Erin?

We decided that Erin would handle the writing duties while I took the reading and pictures. This time around we were supposed to check for signs of wildlife and pick up any garbage. After her last losing battle with mosquitoes Erin came prepared this time. Long sleeve shirts and real insect repellent were in order. She even sprayed me down to try to keep the bugs at bay. It didn’t work.

Woods Creek was pretty much in the same state as the last time we were here. We entered at the first bridge and got to work. We took a few temperature and water conductivity readings and not much had changed. Since I didn’t have to concentrate on the readings, I spent more time checking out what signs of life there were. Erin is more of an herbologist than I am so she kept track of the plant life. She was rattling off plant names and I just took her word for it. I’m not a vegetarian.

Like last time I spotted some smaller bait fish but couldn’t get a good enough look at them to see what they were. When we got to the water thermometers I saw some larger fish hiding underneath the stump but again I couldn’t get a good look to see what they were. What I did see were a lot of crayfish. These guys I was very interested in. I wanted to know if they were native crayfish or the non-native rusty variety.  For the rest of the walk I tried to catch one and for most of the walk my efforts were pretty futile. Just as I was about to grab one it would take off and disappear in the silt. Even with my advance warning system screaming every time one ran across her foot, I still couldn’t corner one long enough to grab it.

Mark had a good time catching and identifying crayfish on his creekwalk.

Mark had a good time catching and identifying crayfish on his creekwalk.

Eventually I caught one and it wasn’t a Rusty. So far so good. I was able to catch a couple more and they were all native crayfish as well. I don’t know what kind exactly, but they weren’t Rusty crayfish. I’m sure the Rusty’s will eventually work their way into this creek but for now no sign of them.

One of the other things we had to do during this trip was pick up garbage. I’m glad to say that there wasn’t much. I expected to find plastic worm containers, fish line, and empty cans. All I really found was some pieces of broken glass and an old shirt.  Nice to see that there wasn’t much trash!

Guest Author: Mark Schaller

Several months back I received an email from the Huron River Watershed Council. They were looking for volunteers for a new program they were starting up, Creek Walking. The council members are trying to collect data on the hundreds of miles of creeks and tributaries that feed into the Huron River. Since funds are tights for this kinds of field work they need volunteers. I volunteered!

I had to attend a training meeting to find out what this was about. I was going to be part of a 5 person team that was assigned to Woods Creek. This little stream is located in Lower Huron Metro Park. My team and I would be making visits throughout the summer to take readings, pictures, clean up garbage and record any observations concerning wildlife or any aquatic critters. Seems simple, right? Oh, was I in for a surprise.

I was worried about the water levels at this time as the prior weekend the levels were about 4 feet above normal and made wading the stream hazardrous.  I stopped by two days prior to our field day and the water had dropped some. My fingers were crossed that a few more days and no rain would finally allow the team to do the initial testing.

On our field day, myself and another teammate, Erin, were the only ones who were able to make it.  The two of us packed up the gear and headed to the stream. The water level was back down to normal so we waded in. After one step I remembered that I never fixed the leak in my hip boots. Erin just waded in with what she was wearing. She soon found out that the all natural insect repellant that she was wearing didn’t do a thing for her. They attacked her in swarms. For some strange reason they left me alone, not that I was complaining.

Woods Creek in July! Looks nice, doesn't it?

Woods Creek in July! Looks nice, doesn’t it?

Part of our work was to take temperature and water conductivity readings. The meter that HRWC gave us takes both temperature and measures the ions in the stream.  Anything under a reading of 800 microsiemens meant that the water was clean and healthy. We had to take a reading every 30 feet and make it with GPS coordinates as well.All of our readings were around 20 degrees Celsius (68 Fahrenheit) and a conductivity of around 800. All seemed good. The stream itself had a gravel bottom the whole length we checked. A good sign for all those Steelheaders out there. A staff member of HRWC told me that they have had reports of steelhead fingerlings this far up the Huron so this may be a viable spawning area for them.

Another part of our job was to take pictures of the surrounding vegetation and make notes of any aquatic or land based wildlife. We didn’t see any critters but did see lots of baitfish in the stream. As far as insects go, there were a lot of damselflies and of course about a gazillion mosquitoes. Because of this and the total failure of Erin’s repellant we hurried through our sampling and got off the stream in a hurry. She was was a little annoyed that I never got bit. Sometimes it’s good to be me.  She was a good sport about it though and offered to enter all our data into the spreadsheet we were given. I volunteered to go through the pictures and the file names and GPS coordinates to the datasheet.

Mission Accomplished! Our task for another day was to walk upstream in Woods Creek and continue the process.

Where are the Mudpuppies?

mudpuppy2The University of Michigan, Eastern Michigan University, and the Herpetological Resource and Management are asking for help in collecting dead specimens of Mudpuppies. Due to the extreme weather conditions this year, herpetologists are anticipating a large winterkill, which provides a unique opportunity to assess population health.

What is a Mudpuppy?

• Michigan’s largest, fully aquatic salamander

Why Are They Important?

• “Bioindicator” species: Due to their sensitivity to pollutants and poor water quality, these salamanders act as an early warning system for environmental problems

• Are the only intermediate host to the Endangered Salamander Mussel

• Great Lakes populations are declining, and the true abundance is currently unknown

How Can I Help?

Place the whole Mudpuppy(s) in ziploc bag, seal, and freeze the bag. Tissue samples may be placed in storage tubes containing ethanol.

Include the following information on a 3×5 card placed within the bag (using pencil) and on the outside of the bag (using permanent marker). In the case of tissue samples, label outside of tube with permanent marker.

1.) Observer

2.) Date

3.) Precise Collection Location

Fall Creek Monitoring: Beautiful colors and beautiful bugs

River and creek sampling

Thanks to 137 volunteers who contributed a total of 548 volunteer hours, the 2013 Fall River Roundup was a great success!  Our volunteers split into 25 teams and traveled to 50 different creek and river locations across the Huron River Watershed to assess the aquatic benthic macroinvertebrate community.

This study is one of the most effective ways that HRWC has to keep its finger on the pulse of the stream. From the data collected from this semi-annual event, we get a better understanding of which creeks and rivers are getting better, which are getting worse, and how we can direct our management activities.

You can see all the results in Fall 2013 River Roundup Report.

Current Watershed Health

In a nutshell, the health of the watershed as judged by our macroinvertebrate sampling is holding steady. Of the 62 sites that we monitor to judge this, 30 sites have had no statistically significant changes over time, and 6 sites are too new to make this judgment.

12 sites are declining, and these include locations on Chilson Creek, Davis Creek, east branch of Fleming Creek, Norton Creek, and South Ore Creek.  The majority of the declining sites are in Livingston County.  Eight of the declining sites are in Livingston, two are in Washtenaw, and three are in Oakland.

14 sites are significantly improving.  11 of improving sites are in Washtenaw County, including Boyden Creek, Horseshoe Creek, the main and west branches of Fleming Creek, Huron Creek, the Huron River in Ann Arbor and Ypsilanti, and several places on Mill Creek. 2 sites are improving in Livingston County (Horseshoe Creek at Merrill Road and Mann Creek at Van Amberg Road), and 1 site is improving in Wayne County (Woods Creek at the Lower Huron Metropark).

 

Highlights

1. For many years HRWC has held up Millers Creek in Ann Arbor as an example of what can happen to an urban creek- the stream flow is flashy, the channel is incised, the riparian vegetation is shrubby invasive plants, and there is little life in the creek.  In 2009 HRWC finished up a green infrastructure project in the headwaters of Millers designed to reduce the amount of stormwater rushing into the creek, and at the same time the City of Ann Arbor finished a major streambank stabilization project where the creek crossed Glazier Way.

The efforts spent restoring Millers Creek seems to be paying off.  The sample taken in Millers Creek at Glazier Way contained the most insect families ever seen since sampling began in 1993. While the overall trend since 1993 is unchanged, from 2004 when the creek was at its worst (3 insect families), until now in 2013 (12 insect families), there is a statistically significant increase.  Insects that are particularly susceptible to pollution and disturbance have yet to be found here however, and we will continue monitoring in hopes that these insects will make their way back to the stream.

2. Starting in this past January, HRWC has been sending volunteers to two new stream sites on Portage Creek near Stockbridge.  This is a long drive from Ann Arbor and we appreciate the volunteers who have made this journey. This Roundup, volunteers in the Portage Creek at Rockwell site found a treasure trove of insect diversity.  Twenty insect families were found which puts this new site up there with the very best places we go.  We will look forward to visiting this site again in the future!

Norton creekshed in Oakland County is a Detroit suburb and industrial hub. Historically, the creek has suffered from numerous impairments and has seen little improvement as the area has become increasingly suburbanized.

In terms of the macroinvertebrate community, samples taken here have always had terrible diversity and low abundance, but in recent years things have gotten worse.  When sampling started in Norton Creek at West Maple Road in 2000, it was normal to find between 8 and 10 insect families.  However, volunteers during the past four fall River Roundups have found 3, 4, 4, and 3 insect families.  Two of the insect families found are actually water striders, which are only semi-aquatic as they live on top of the rather than in the water.

These poor samples have made Norton Creek the worst location of all of those that HRWC monitors. For more information on Norton Creek, see our Norton Creek page and associated creekshed report.  http://www.hrwc.org/norton

 

What’s next?

On January 26th, HRWC staff and volunteers will gather for the 19th annual Stonefly Search.  This event is very similar to a River Roundup except that we are only looking for stoneflies.  Some of these little guys can be found year round, but there are a couple of stonefly families that are only reliably found in the winter months, and they are great indicators of healthy water.   We hope you and your family and friends will join us for this fun outdoor event!  Register here! http://www.hrwc.org/volunteer/stonefly/
