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!
We have a paddle trip for people looking for adventure and an interest in trying their skills at biking and paddling. This Sunday, September 21st, at 1:00 we are hosting a paddle trip from Hudson Mill Metropark to Dexter-Huron Metropark with a bike to the beginning along the recently completed border to border trail.
Ron Sell and Barry Lonik, experienced paddlers (and bikers), will be leading this trip down a beautiful stretch of the river in the Natural River’s zone. Elizabeth Riggs, HRWC’s River-Up Manager will be on the trip too, adding her expertise and knowledge of RiverUp! and Huron River Water Trail improvement projects within this section of the river. Join the fun and learn about the river and try your skill with paddling and pedaling! Register here.
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.
That’s right! HRWC will pay the April water bill for three lucky families in the Huron River watershed, up to $250 each!
HRWC’s “Pledge, Save, Win” Contest encourages watershed homeowners to make the connection between water and energy. Saving one, means saving the other. Up to 13% of our nation’s electrical energy goes to pumping, treating and heating our water supplies.
There are just three steps for entering.
1 — GO to www.h2oheroes.org, to watch a 60-second public service announcement.
2 — PLEDGE to do one or more activities to save water daily.
3 — REPORT what you did to save water by March 31, 2014. Reporting can come in the form of stories, videos, photos or other creative ideas. Winners will be selected based on creativity and effectiveness.
To help jump start your family’s efforts, www.h2oheroes.org has many tips and tools, including an online savings calculator, and a map to verify that you live in the boundaries of the Huron River watershed if you don’t know.
Winners will be announced by April 15, 2014.
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.

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).
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
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/
Want to meet the Lions, Tigers, and Bears of the Huron?
We’re happy to show them off – but you’ll have to help us hunt them down! (Though ours are a tad smaller, as they are aquatic insects.)
Join us on Saturday, October 12 for HRWC’s autumn River Roundup. You can bring a small group of friends or we’ll put you on a team with other awesome HRWC volunteers. The outing takes about 4 hours and starts at either 9:00 or 10:30 am (you get to choose!). We’ll send you to some really cool spots around the watershed to track down some of those critters. When you return we’ll have a nice snack to share over your stories in the wild!
For info and to register, please check out www.hrwc.org/volunteer/roundup.
*Lampyridae, Tabanidae, and Belostomatidae are, respectively, fireflies, horse flies, and giant water bugs – OH MY!!
This spring saw two nice river cleanups and a clearing workshop. In April we hosted a guest presenter from the Friends of the Rouge to help train new and experienced HRWC volunteers. William Craig who co-created the Clean and Open method taught how to take out enough woody debris for river paddling, while leaving as much debris as possible for healthy stream ecosystems.
Earlier in May we had two river cleanups. A dozen volunteers paddled from Dexter Huron to Delhi Metropark. Simultaneously, another dozen folks on floatboats put in at Flat Rock and picked up debris down to South Rockwood.
A Little Work To Do…
Woody Debris Removal. We need a few more folks to help our newly trained woody debris removers. No experience necessary, but a willingness to get dirty and wet while being safe and helpful!
Stream Walks. Join us on June 9 (2pm) to learn how to walk the Huron’s tributaries and identify problems you see along the way.
If you’re interested in either of these contact Jason, firstname.lastname@example.org.
A HUGE thanks to REI for financially supporting the River Scouts programs over the past three years, and continuing that support this year! Thanks goes to Green Oak Township for allowing us to use your conference rooms! Thanks to Bill Craig for sharing his expertise and experience. Thanks to Schultz Outfitters for coordinating the Flat Rock cleanup (and buying hotdogs!). Thanks to the City of South Rockwood and Delhi Metropark for picking up the trash after we delivered it! Thanks to the Huron River Fishing Association for showing up in force! Thanks to Skip’s Canoe Livery for loaning boats for the Metropark cleanup! Thanks to Whole Foods for the snacks! And, of course, thanks to all the volunteers for your hard work, inspiration, and perspiration!!!
Saturday turned out to be a lovely day for HRWC’s Stonefly Search. 110 volunteers returned safely from the field after successfully accomplishing their mission. These hardy souls endured the snow, enjoyed the sun (briefly), had fun breaking through the ice, and learned about the Huron and the critters who live here. Interesting finds included a slumbering frog, mute swans, and Canada geese (not to mention lots and lots of insects). Look for a detailed report from Paul Steen regarding the Stonefly results. Until then, here is a bit of verse to paint a picture of how the day went for many…
Winter Stoneflies in Arctic Michigan
By Dave 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 stone flies
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.
