Explore tubing on the river between Dexter and Ann Arbor
If you’ve never tubed on the river you should try it. At first I was intimidated by the young, more rowdy crowds of tubers but found quickly that tubing can be a quiet, cooling, and beautiful way to experience the river. The tubes are relatively inexpensive. Grab a pump that can run off your power outlet in your car. Pick a hot day and leave a bike or car at the Washtenaw County Stokes-Burns Park on Zeeb Road and then head to Dexter-Huron Metropark.
The rest is easy. Relax into your tube (wear a bathing suit or shorts that can get wet) and the steady current will take you gently down the river. The mile-long trip takes about an hour and a half and takes you through a beautiful stretch of the river where you catch glimpses of fish, very large and colorful dragonflies, indian paintbrush plants, herons, osprey, and other plants and animals I can’t name. On a hot day, its just about perfect! We do try to avoid the weekend river rush-hour and usually have a very relaxing experience.
If you are looking for a more lively adventure with lots of people and action, check out Tube the River from the City of Ann Arbor for info on trips through the Argo Cascades.

My work in the environmental field makes me familiar with the many things we can do at home to protect the environment. But it takes money and time to act on these tips. This past year we were finally able to work on a few “greening” home improvements, shared here for inspiration . . .
Last year we reached out to the Washtenaw County Water Resource Commissioner’s Office to help develop a plan to capture and infiltrate more of the runoff from our roof. Years ago we installed a rain barrel but it is limited to 50 gallons per rain, with use in between rains. I live in Ann Arbor on a pretty small parcel and there is not much room for rain storage and infiltration…or a garden. But we were able to identify 2 different rain garden locations—one a swale along one side of the house and another in the front of the house.
After choosing plants and a design we installed the rain garden last spring—digging, mulching, and placing rocks and native plants strategically for rain water capture and aesthetics.
At first it didn’t look like much but as the summer and fall wore on the plants blossomed and grew. We enjoyed running outside when it was raining to see the water gushing out of the gutter/downspout and in to the rain garden where it soaked in to the ground. We found out that we have pretty sandy soils, unusual for this area, so the water soaked in quickly. If anything, we can divert more runoff to this garden it was so “thirsty”. I also learned, through trial and error, what was a weed and what wasn’t. Staying on top of the weeding is the biggest challenge now that the rain garden is in.
Last summer we also decided to install solar panels. Since we had last looked in to solar panels the cost has come down substantially. There are also substantial tax incentives in place this year that help with the price of the panels. We got quotes, talked with colleagues and friends who had installed panels and chose an installer, Homeland. It took over 4 months until the system was up and running but in early November we were generating electricity! We’re still getting familiar with how it all works but we have a nice looking box in the basement that hums when we are generating energy and a website to track our power generation. We’re looking forward to the summer when the sun really shines to see how much energy we can generate and reduce our carbon.
If you are considering home improvements, or even smaller actions that help protect the environment, HRWC promotes many of them at our Take Action pages. Our booth at the Home, Garden & Lifestyle Show, March 18-20, will feature two sustainable landscaping experts providing free information on rain gardens and native plants: Susan Bryan leader of Washtenaw County’s Rain Garden Program (Saturday) and Drew Laithin of Creating Sustainable Landscapes (Friday/Sunday).
Susan also wrote the cover story for the Spring 2016 Huron River Report, sharing success installing private rain gardens in our Swift Run Project and offering some great tips for those considering DIY rain gardens. Take a look, its a good read and will inspire you to start a rain garden movement in your neighborhood.
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.

Streams ranked from best to worst: Where does your favorite fall?
On October 3, HRWC volunteers spread across Oakland, Livingston, Washtenaw, and Wayne Counties and looked for the aquatic insects and crustaceans that indicate the water and habitat quality of our river and creeks.
Using this and other environmental data collected by HRWC volunteers over the past 20 years, I have developed a ranking of the various streams in the Huron River Watershed. Streams listed at the top of this list have the best aquatic life and habitat in the Huron, and streams at the bottom of list are extremely impaired with little aquatic life and highly disturbed habitat.
Volunteer-collected data directly contributes to our knowledge of the conditions of the watershed and is a key component in directing management and restoration activities.
If you want more details on the ranking below, HRWC will present it and other data findings on January 12, 2016, 6 pm at our office (1100 N Main Street, Ann Arbor). All are welcome and no registration is required.

HRWC recently hosted the first Michigan Aquatic Restoration Conference (MARC) with partners at the U.S. Fish and Wildlife Service, Forest Service, Michigan Departments of Environmental Quality and Natural Resources, as well as business sponsors Stantec, North State Environmental, Inter-Fluve, and Spicer Group. Located at the retreat setting of the Kettunen Center, the MARC brought together over 120 agency and academic scientists and engineers and industry professionals from all over Michigan as well as several other Great Lakes states. Much of the conference focused on geomorphology, or the study of the processes that shape a river channel and produce the habitat that exists in its present state.
The MARC was led off with a workshop on “Woody Debris Management” by one of the founding fathers of geomorphology, Dr. David Rosgen from Wildland Hydrology. He also provided a keynote presentation on lessons he has learned from more than two decades of stream restoration work. National restoration expert Will Harman from Stream Mechanics discussed a popular conceptual framework he developed — the “Functional Pyramid” — and discussed how restoration practitioners should seek to provide rivers and streams with “functional lift.”
Other presentations and discussions focused on the various and sundry nuances of stream restoration in practice throughout Michigan, the Great Lakes region, and parts south and west. There was a genuine excitement in the air throughout the conference as participants engaged in vibrant discussion about how to apply principles (some theoretical at this point) to stream restoration, in what is a relatively new applied science.
If you missed the conference this year, check out the MARC website for a sampling of the presentations and discussions, and keep your eye out for an announcement of the next iteration.
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.
On June 3, generic 2015, the Huron River Watershed Council started sampling at 10 sites on Norton Creek, located in Oakland County. In addition to water quality monitoring, volunteers and interns are also assessing the area by looking at the road/stream crossings, creek walking and paddling on the creek, and conducting neighborhood assessments.
Norton Creek, a tributary to the Huron River, drains 24.2 square miles and is located in portions of Commerce, Lyon and Milford Townships, and the cities of Novi, Walled Lake, Wixom and Wolverine Lake in Oakland County.
The Michigan Department of Environmental Quality designated Norton Creek as impaired due to excess sediments and low dissolved oxygen. Dissolved oxygen refers to the amount of oxygen that is available in water, and it is essential for aquatic life and good water quality. The cause for low dissolved oxygen in Norton Creek is attributed to high biological and sediment oxygen demand — meaning that algae and bacteria are consuming all available oxygen, leaving none for bugs and fish.
HRWC was awarded a SAW grant (Stormwater, Asset Management, and Wastewater Program) to fund the Norton Creek project. Based upon the data collected from our monitoring efforts, a watershed management plan will be developed to address and fix the impairment.
The extent of impairments and the likely source contributions will be evaluated, along with the development of a realistic prescription of remediation, restoration, and protection actions. HRWC has been and will continue to work with key stakeholders and concerned citizens in the Norton Creek communities in a collaborative effort to help restore this at-risk creek.
We want to thank the volunteers and interns who are helping HRWC with the data collection effort! It is because of your help that we are able to quickly and efficiently gather the data we need to develop an effective watershed management plan to improve Norton Creek!
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/.
