Aquatic insect sampling on the Huron River and its creeks
Thanks to 154 volunteers who contributed approximately 600 volunteer hours, the October 2016 River Roundup was a great success! As always, HRWC 100% guarantees good weather for its volunteer events or your money back. We were once again able to fulfill that promise!
It was a very full house here in the HRWC conference rooms before the 18 teams split up and traveled to 36 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 understand how the water quality of the river and creeks may be changing. From the data collected at this semi-annual event, we are able to keep abreast of the health of our waterways throughout the watershed. You can see a summary below, or detailed results in the October 10 River Roundup Report.
Current Watershed Health
HRWC gives a rating to each site that we monitor (Excellent, Good, Fair, or Poor). The graph above shows this breakdown for the 61 locations that HRWC considers representative for the watershed. The detailed River Roundup report gives the site condition for each location.
Overall, the health of the watershed as judged by our macroinvertebrate sampling is holding steady, though there are particular areas getting worse or better. 30 sites have had no statistically significant changes over time, and 4 sites are too new to make this judgment.
Fifteen sites are declining, and these include locations on Norton Creek, Horseshoe Creek, and Honey Creek (Washtenaw Co). Ten of the declining sites are in Livingston County, 3 are in Washtenaw, 1 is in Oakland, and 1 is in Wayne.
Twelve sites are significantly improving. Eleven of the improving sites are in Washtenaw County, including locations on Mill Creek, Malletts Creek, Fleming Creek, and the Huron River. 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).
There were a lot of highly diverse samples collected this season. The team at Pettibone Creek: Commerce Road in Milford collected the most diverse sample ever taken at the site (sampling started here in 2001).
Two sites on South Ore Creek were diverse enough to pull these creeks out of a statistically significant decline and into the “declining but not significantly so” range.
The sample taken at Davis Creek off of Silver Road was the best sample taken in about 8 years.
For some teams, sampling conditions were difficult. The Huron River was running fast and deep after the area received heavy rain just a few days before the event started. The sample taken at the Huron River at Zeeb Road was particularly bad and far outside the range of normal variation. Based on the volunteer’s feedback and the difficulty of sampling the river, this sample was marked as an outlier and will not be included in the long-term record for the site.
Want to learn more about the data that HRWC collected this past year? On January 19th at 6 pm at our office on 1100 N. Main Street, HRWC staff will present results and interpretation for all of the field projects conducted within the past year. Good indoor weather guaranteed!
Do you consider yourself a Michigander, or aspire to be one? Then you should brave the cold and join the Winter Stonefly Search on January 21. It is like the River Roundup, only much snowier and usually colder. Good weather guaranteed or your money back… but of course these events are always free! You can register for the event here.
The 2016 Water Quality Monitoring Program season wrapped up at the end of September, and now I spend time compiling the data for analysis. With the help of 60 volunteers between April and September, we gathered water samples for chemistry analysis at 37 sites throughout Washtenaw, Wayne, and Livingston Counties. Flow measurements were also taken at several of those sites. Monitoring sites are visited up to 12 times during the season, and it would be impossible to gather this much information, or visit as many sites, without the help of volunteers. We are able to gather critical watershed data, as well as keep eyes on the Huron River and its tributaries for potential problems and risks such as erosion and pollution. I am proud of this program, it allows citizens to become actively involved in protecting the Huron River watershed and the water we rely on for so much. Thank you, volunteers, for helping us.
Mark your calendar for January 19, 2017 at 6:00pm and come to our Volunteer Appreciation and 2016 Field Season Results Presentation.
As mentioned in the Summer 2016 HRWC newsletter, both Barton and Argo Pond on the Huron River are home to a new exotic aquatic plant, the European Water-Clover (Marsilea quadrifolia). In 2015, Michigan DEQ alerted HRWC that this plant was only in two places in the state, Barton/Argo Ponds and a location in the Clinton River Watershed. However, they were unaware of how widespread this plant was in our system. In 2015, HRWC volunteers searched those ponds and found many patches of the plant and reported their location back to DEQ.
The scientific community at large is generally ignorant about the European Water Clover; people do not know how it spreads, to what extent it can out-compete nearby native plants, and how it might change the ecology of the system. This is often an issue with new exotic species; scientists often don’t know how damaging something will be until it becomes a problem. It is important to get a handle on these new plants, though, because you can’t predict when the next Phragmites will arrive- a plant that spreads very rapidly and changes its ecosystem. And any control methods have to be done very carefully, as so many plants (such as Eurasian Water Milfoil) can actually spread faster and further if they are carelessly ripped out.
This past spring, HRWC put a monitoring plan together with DEQ. To determine when the plant first emerged, HRWC visited two known problem areas weekly in Argo and Barton Ponds through the late spring and early summer. The water clover was first detected in early June.
To determine possible spread of the water clover, HRWC and DEQ waited until early August of this year, when the plant would be at its full summer growth, and surveyed upstream of Barton Pond, from Delhi Metropark to the Maple Street Bridge. Thankfully, that section of the Huron River was clear of the plant. It does seems that the plant strongly prefers very slow water, and the Huron upstream of Barton generally flows at a moderate to rapid rate.
HRWC is planning additional monitoring downstream, through Gallup Park and Superior Pond, which contains more promising habitat for the plant. DEQ is also planning to try out some control methods, conducting both herbicide treatments in a greenhouse and an exclusion method using a mat that covers the plants in the river.
HRWC will continue to watch this exotic plant and report out as more is learned about European Water Clover in the Huron River system.
Best way to get to Kensington
Get carried away on the north side of the ‘shed
One my my favorite vacation days last summer was when my hubby and I rented a kayak from Heavner’s for an afternoon ride on the river. Heavner’s is in the Proud Lake State Rec Area so our trip started with an ‘instant, just add water” effort for gaining immediate access to nature. We loved pushing off the dock and into a peaceful path bordered by tall grasses and trees.
After a very easy paddle for about 2 miles, we entered Milford, a cute town with a gorgeous bridge that looks like a portal to Narnia. If we had known about the River’s Edge Brewing Company in Milford, we certainly would have stopped for a beer. Our oversight was a novice mistake that can easily be avoided now that our Huron River Water Trail site is launched. [Novice tip: before heading out, go to the site to find fun places to stop, sip, and snack in any trail town. Here’s a link to Milford’s page–check out the links in the map to plan ahead for fun places to visit.]
Past Milford, we spotted a pair of humans — less abundant in this area than farther South — who delighted us by “pulling over” to remove trash from a party spot along the shore. I was pleasantly surprised to see one of them sporting a Huron River Watershed Council volunteer t-shirt. (Way to represent, peeps!)
We ended our trip at the agreed upon pick up spot in Kensington Park and the Heavner shuttle driver arrived on-time to take us back to our car. The whole trip was very easy and we could have gone for several more miles. Next time, we will!
Have fun, stay safe with these TIPS from the Trail.
Join HRWC for Huron River Appreciation Day, Sunday July 10! Come along on a guided trip of the Huron River Water Trail in Dexter, paddle the Lower Huron from Flat Rock or paddle to Milford from Proud Lake, hear a talk on paddling safety and get a free life jacket, hear a river history talk or learn to fly fish!
Huron River Appreciation Day is sponsored by TOYOTA.
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!
