Earth Day falls on April 22 this year, and not accidentally, so does HRWC’s spring River Roundup. Perhaps the idea of Earth Day may strike you as a little disheartening this year, in our current political climate of science and environmental budget cuts, and widespread doubt in scientific data. Are we making a difference at all? Or is our country reverting back to an era of rivers catching on fire? What is so disheartening to me personally is not a looming Federal budget that will remove funding for the Great Lakes and environmental regulation (though that is terrible, don’t get me wrong, but I’m not surprised by this), but to see so many people who agree with this course of action. Still, there is room for hope in our future, and that hopes lies in you—the many people who want clean water and clean land and who stand strong with HRWC to work for it.
Consider volunteering with us. Every participant makes an immediate difference at our local level. HRWC volunteers collect scientific data in southeast Michigan, primarily in Oakland, Livingston, Washtenaw, and Wayne Counties. For the upcoming River Roundup on Earth Day, volunteers will be looking for aquatic insects that tell us about the health of the Huron River and its tributaries, and ultimately about the health of all the land that drains into the Huron. This information gives HRWC the knowledge to conduct effective river management projects and the authority to speak intelligently on water quality issues with local, state, and federal government, landowners, and other decision-makers.
And in the process of collecting scientific data, HRWC volunteers are learning and teaching others. It is always so exciting to see the adult HRWC volunteers interacting and teaching children, teens, and college students about river systems, insects, and the environment. And in as many cases, to see the kids teaching the adults! This is the type of education that will create the long term cultural change needed in our country.
Make a difference locally by acting now to help HRWC collect scientific information that informs our management decisions and local policies; change the future by teaching the younger generation in the process. The River Roundup is on Earth Day, April 22. Learn more about the River Roundup and register at http://www.hrwc.org/volunteer/roundup/
In the last 2 months I’ve been asked a lot about my thoughts on sustainability and climate going forward. At a recent climate rally I shared what we do best at HRWC—the climate science and trends, and what people can do.
Here is a synopsis of my comments:
For 50 years our job has been to study and protect the Huron River, which runs right through many communities, including Ann Arbor. We have 25 years of data about this ecosystem. And the data confirms what we’ve seen this February. We have a migrating climate. Days like this are what we would have expected to see in Kentucky 20 years ago. Within 50 years our seasons will feel more like Oklahoma. This has massive implications for our natural ecosystems and our economy, and our quality of life!
So let me tell you about what our science shows us about Michigan today:
- It’s warmer. Annually by 2 degrees F; by 2070 an increase of 3.5 to 6 degrees.
- Today, the growing season, or the frost-free season, has gotten longer by 9 days. In the future, it could increase by 1-2 months.
- Today, Michigan gets more rain and snow—an 11% increase. In Ann Arbor 24% more.
- The strongest storms have become more intense and more frequent. These rain storms are so heavy they overwhelm our storm sewers, our dams, and our wastewater treatment plants.
But, that’s facts and figures, let me tell you a couple of stories about how that affects us all.
- People might remember that three years ago, a rain caused flooding in our watershed and in particular, on the UM campus. It was so intense and with so much water, students kayaked down the East University Street.
- HRWC researches the river. Every January, we send about 100 volunteers out, up and down the river, to collect Stoneflies. Stoneflies are little bugs that are sensitive to changes and pollution, so they tell us how healthy the river is. Two years ago we had to cancel because of the extreme cold. The volunteers couldn’t break the thick ice to get in to the river. This year, we had the opposite problem: our volunteers could not get in the river in certain places due to high flows from a 50 degree thaw. We heard from volunteers that they were already seeing stoneflies that had hatched rather than in their larval stage. This means that when the fish start spawning in April, they won’t have as many stoneflies to eat….that damages the entire aquatic ecosystem.
So we’ve had an extremely warm February, but these unexpected extremes should now be expected.
So what can we do about this? Engage, engage, engage. I hear from people day in and out that they are frustrated and yearning to take action. We need big change; to change the way we operate major infrastructure systems of this country—transportation, energy, stormwater, housing, waste, and food.
As somebody who has spent my career working on environmental issues, here’s what I find effective: 1. Take individual steps on your own and with your family; 2. Build connections with people (your colleagues, elected officials, friends, neighbors) to work on issues at a larger scale.
Stand up against the things you don’t want (a weaker EPA, the Dakota pipeline, Line 5), but at the same time take actions to create the things you do.
There’s lots of things we can do as individuals. We also have elected officials, business, and government employees, and it’s important to do things collectively and scale them up.
- To change our transportation systems, Take the bus—and advocate for robust public transit;
- To change our stormwater systems, Put in a rain garden or rain barrel—and work with neighbors to push your university or town to install better rain capture systems on roads, parks, and rooftops;
- To change our energy system, Put in solar—and help your elected officials pass tax incentives and ease of permitting for alternative energy; and
- To improve our housing system, Live near your work or school—and encourage affordable housing so others can too.
Finally, it’s important to volunteer—engage in your community, sit on a board or commission. This is tough but necessary work. This is where change is made.
In my work as Director of HRWC, I bring very different people together to protect something we all love, the Huron River. I do that by talking to everyone who plays a part—farmers, drain commissioners, hunters, anglers, politicians, scientists, and homeowners. We’re all really different people with different political perspectives. We don’t always agree, but we find ways to make real change. Because all these people work together, the river is cleaner than it’s been in 50 years. It’s that steady engaged work that makes a difference and gives me hope.
Go get involved, take up the challenge, and let’s get to work!
Here are some of our projects that exemplify how our partnerships address climate change.
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.
Get Outdoors and Support the Huron River!
We need volunteers to join our natural area field assessment teams!
Get outside, meet new people, learn about our local natural areas and help out HRWC’s Bioreserve Natural Areas Assessment program! HRWC is seeking field volunteers to help inventory ecologically important natural areas in the watershed.
Volunteer teams will be conducting rapid ecological assessments of grasslands, forests, wetlands, and aquatic habitats throughout this spring, summer and fall. Each visit is like a nature hike through a new woods or wetland.
The 2016 season marks our nineth field season; volunteers have so far assessed over 300 properties throughout S.E. Michigan. These efforts have helped protect over 6,000 acres of land in the watershed. Land conservancies and community preservation programs use the data gathered to promote permanent protection of those lands identified as the highest quality and most important for protection of the Huron River.

at Independence Lake County Park, in Whitmore Lake
January 23rd was a beautiful day for the annual Stonefly event. The weather hovered around 30 degrees and the sun shone nicely throughout the volunteers’ time outside. They were searching for stoneflies, an insect that only lives in the healthiest creeks and rivers. The absence and presence of stoneflies, and the trends in their population that we see after visiting a location over and over again, give us clues as to how the water is changing over time.
Unfortunately for the purposes of data analysis and clear-cut answers, stoneflies are affected by more than water quality, however. Strange weather can also play havok on their ecosystems, causing populations to drop off. Our volunteers came back with very low amounts of stoneflies this year, and while we can’t be certain, it is possible that our variable Michigan weather is to blame. You may recall that December was unseasonably warm in 2015, and wonder how that might affect the insects. However, in this case, it wasn’t a warm December that hurt the stoneflies, but instead February 2015, a month that was extremely cold. In fact, it was one of the coldest February’s on record. When streams and rivers are covered by thick ice, oxygen levels decline, which is bad for all aquatic life but particularly bad for stoneflies, who have high oxygen requirements. Also, February and early March are when winter stonefly adults are emerging, mating, and depositing eggs; all activities hampered by extreme cold and ice cover. In summary, the cold 2015 winter had direct consequences for the stoneflies in 2016.
Volunteers did not find stoneflies at many places this year, but five locations in particular that did not have stoneflies were noteworthy as all of them have a long (10+ years) history of always holding stoneflies. In addition, all of these locations have great insect populations at our other events and there are no indications of water quality issues, further strengthening the argument that this year was a weather-related population decline. These five locations were three places on the main branch of the Huron (White Lake, Zeeb, and Bell Roads), Arms Creek at Walsh Road, and Boyden Creek at Delhi Road. Many other locations had reduced numbers or family counts.
Those interested in all results can see them here: PDF report.
Prior to the event, I laid out several examples of things that we would watch for this year:
Davis Creek at Pontiac Trail: Stoneflies have been dropping off here for the past decade. Volunteers did come back with stoneflies this year, though not the winter stoneflies but rather a family that is more widely available. Still, this is good news.
Honey Creek at Wagner Road: Stoneflies were missing here in 2014 for the first time, and unfortunately volunteers did not find them this year either.
Woods Creek at Lower Huron Metropark: Just like Honey Creek at Wagner Road, stoneflies were not found here for the second year in a row.
Insect populations are resilient and can bounce back with good water quality and suitable weather conditions. While this year was disappointing, the mild winter we are experiencing right now may result in a bumper crop in 2017. Come next January, HRWC and its volunteers will be ready to check it out!
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.

Read articles on issues with water infrastructure in our watershed and Michigan-wide. Earlier this month the US Federal Court of Appeals made a ruling on a pesticide known to kill pollinators. Our water trail continues to make headlines. And the Swift Run creekshed is getting some special attention these days.
Ten surprising facts in Michigan’s new water strategy
In July, Michigan released a draft 30-year water strategy. Much public discussion on the strategy has occurred since then. This is a blog written by Brad Garmon at the Michigan Environmental Commission that takes a little different look at the strategy. Brad captures some startling statistics on the water assets Michigan owns and must steward.
Supervisor: Overuse causing discolored water in system
Lyon Township residents have been experiencing trouble with their drinking water. While the water remains safe to drink, some people are finding their water discolored. The township Supervisor attributes the color to iron in the water that occurs when backup wells are used to meet increased demand. The article highlights the issue of aging infrastructure with population growth and increasing water demand common throughout our watershed.
Michigan’s top 11 water trails named
The Huron River Water Trail was named one of the top water trails in Michigan by a public vote conducted by the Michigan Department of Natural Resources. But we knew that already didn’t we? Click through to see other awesome river destinations throughout the state.
Court: EPA Should Not Have Approved Bee-Killing Pesticide
A step in the right direction for the honeybee crisis. Bees and other pollinators have be in rapid decline. An agricultural chemical, sulfoxaflor, has been found to be one contributor to these declines. The lawsuit shines a spotlight on the role of federal regulators in this complex problem and will hopefully encourage more extensive testing of new chemicals before receiving EPA approval.
Swift Creek Improvements
HRWC’s Ric Lawson talks about a project we have underway to improve stormwater management and water quality in the Swift Run tributary of the Huron River. Learn about the problems in Swift Run and the solutions HRWC, Washtenaw County and the City of Ann Arbor are supporting to improve the river.
Looking for a way to expand your knowledge about ecosystems, rx invasives, and the history of conservation in Michigan?
The Michigan Conservation Stewards program has been brought back to Washtenaw County by a collaboration of HRWC and peer organizations. We hope you, capsule as a supporter of the Huron, will take the opportunity to strengthen your knowledge and thus ability to advocate for our natural resources. This 6-week course covers all the basics of conservation, tadalafil introduces participants to a wide-array of topic experts, and is a great networking opportunity.
