It is January, which means that one of HRWC’s favorite events, the Stonefly Search, is right around the corner.
Stoneflies are interesting because they are the most pollution intolerant group of aquatic insects that we have in Michigan. They can only thrive in the cleanest water with high levels of dissolved oxygen. When they are found at a location it is a confirmation of high water quality, and when they disappear from a stream it is a warning sign that water quality has degraded.
It might seem strange to many that we hunt for stoneflies in the winter. This is because two of the stonefly families, the Capniidae and the Taeniopterygidae, change from aquatic nymphs to terrestrial adults in the late winter and early spring. This means that we can’t find them during the normal April River Roundup, and so we have to look for them earlier in the year!
The Stonefly Search always produces interesting results. Let’s take a look at some of the findings in recent years.
Reported in 2013: Four sites had the best stonefly samples that had ever been seen at those locations: Chilson Creek at Chilson Road, Fleming Creek at Galpin Road, the Huron River at Flat Rock, and Woodruff Creek at Buno Road. At each of these sites, the stoneflies normally found at the location were there, but also new stonefly families were found that had never been seen there before! A greater diversity of stoneflies indicates greater stream health. These are promising results and hopefully it will continue into longer term trends.
Reported in 2011: Since 2007 and up through last year, our volunteers have found 4 families of stoneflies in Mann Creek. This includes 2 stonefly families that can be found in creeks year round (Perlidae & Perlodidae), and the 2 stonefly families that are only found in the winter (Capniidae & Taeniopterygidae). Even in the Huron’s healthiest streams, it is unusual to find more than 2 families of stoneflies during the Stonefly Search. So, Mann Creek is special indeed. Mann Creek flows through a residential neighborhood- but one really interesting thing about Mann Creek is that there is a very wide natural riparian zone surrounding the creek. This riparian area provides habitat and food for stoneflies as branches and leaves fall into the creek. To see Mann Creek and its impressive riparian zone, click here.
Reported in 2015: Davis Creek at Pontiac Trail (near South Lyon) is a 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.
Reported in 2015: The team searching for stoneflies in Honey Creek at Wagner Road (Ann Arbor) 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.
Reported in 2013: The team searching for stoneflies in Woods Creek in Belleville came back disappointed. Wood’s Creek at the Lower Huron Metropark has been sampled 12 times since 1997, and this is the first time that stoneflies could not be found. The problem likely comes from the thick ice and difficult conditions rather than pollution or disturbed stream habitat, but we will keep an eye on Wood’s Creek next year.
What will we find in 2016?
Will Mann Creek continue to reign as the king of Huron River stoneflies? Will we find stoneflies where they have never been before?
Will we find stoneflies this year at Davis, Honey, and Woods Creek, or has the water quality there continued to decline?
We will see you on January 23 and we will answer these questions together!
A Celebration of a Very Cold Event
by Dr.David Wilson
We don our coats and boots, go forth to break the ice
In frigid, frosty weather that no one could say is nice
We flounder through the streams in search of a great prize
Taeniopterids and Capniids, precious winter stoneflies
Winter stones are quite the thing
Though one surely might be wondering
How these tiny creatures could ever be so bold
As to live and thrive in this bitter winter cold
Paul tells us that in winter these critters really thrive
Cold water holds the oxygen to keep them all alive
And winter is helpful in another major way
The cold keeps fierce predators so very far away
Quite sensitive to any water pollution,
Winter stones provide a quick solution
If we find ‘em we can be sure
That the stream is sweet and pure
The critters are small and rather dark
In this frigid weather they have a lark
Scamper about in the ice and snow
There’s no other place for them to go
To ID them here’s what you do
Look for wingpads four and cerci two
Along the flanks no gills are found
And on each leg two claws astound
The ice is thick, the water chills,
With cold I’m fed up to the gills
But none could say that we are quitters
We’ll search ‘til we find those little critters
Believe me, I know whereof I speak
You’ll find out fast if your waders leak
One hears screams of pain from the bravest jocks
When that icy water hits their socks
Collectors and runners can stay in motion
Stay warmer thus, I have a notion
But picking requires that one stand still
Can be quite bleak, cause many a chill
Don’t go on ice unless waders you wear
If you’re not wearing waders your weight it won’t bear
If you should venture this dumb thing to do
I guarantee you’ll surely break through
Let me warn you right now; listen up and take heed
Bring twice the wraps you think that you’ll need
That usually turns out to be about right
So that you are not left in a piteous plight
A jug of warm water is always quite pleasing
Helps to keep that D-net from freezing
And stout rubber gloves keep collectors’ hands dry
Help a great deal when frostbite is nigh
On these trips a truly most gracious amenity
May help the participants keep some of their sanity
A big jug of cocoa sure hits the spot
Beloved by all if it’s nice and hot.
Stonefly Search is coming January 23! Registration and info here.

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.
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.
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.
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!

Stonefly Search 2015 Wrap Up
A Surprisingly Pleasant January Day
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!
The adventure comes to a close!
Are you interested in being a creekwalker? You can recruit your family and friends to join you on your team or ask HRWC to assign you to a team. The training is on June 10, 6:30- 8 pm. Check out this webpage and email Jason at email@example.com to volunteer.

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!
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.
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.
Our big thanks go to Mark and Erin, and all our other creekwalking volunteers, from this past summer!
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.

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.
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.
The adventure continues!

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.
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.
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!
Stayed tuned for the third and final part of Mark’s creekwalking experience.
Inspire River Protection With Art!
Come decorate the curbside connections to the Huron River! Ann Arbor artist David Zinn and Karim Motawi will lead the crowd in chalking four of our downtown stormdrain inlets into works of art. We provide the chalk, you bring the creativity!
When: Friday, June 13, 2014, 6-8pm
Where: The Ann Arbor Mayor’s Green Fair, at the Liberty and Main intersection and the Huron River Watershed Council booth in front of the Melting Pot.
Presented by HRWC in partnership with the 14th Annual Mayor’s Green Fair and the Ann Arbor Public Art Commission.
We depend on stormdrains to keep our streets from flooding during storms. Yet, these devices also direct litter and polluted rainwater straight into the Huron River. We’ll show and tell the stormdrain connection and recruit families to adopt their neighborhood stormdrains, keeping them for rain only by removing litter, leaves and other debris in the spring, summer, and fall months.
