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.

PHOTOS and STORY: Get a sense of what this event is like from a HRWC volunteer here.
One of the perks of my job as a co-director of the Adopt-a-Stream program at HRWC is that I get to see places that many others miss out on. And so while I love the main branch of the Huron River and spend many hours at our metroparks, I decided to focus on a small creek in Webster township– Arms Creek.
Arms Creek at the intersection of Walsh Road is known internally here at HRWC as “Adopt-a-Stream Site Number 1″, meaning that it was the first site to be picked as a part of the program way back in 1992. The watershed council and our many volunteers have been visiting this location and collecting information on this creek for 23 years! The creek contains many insect families that are sensitive to pollution and their presence tells us that the creek has good water quality. In fact, the insect population has been getting better over time, so conditions here have improved over the past 20 years. A thick riparian zone of trees and shrubs provides ample shade for the creek and plentiful groundwater inputs keep the water quite cold. Many decades ago, the DNR actually stocked Arms Creek with trout, which is very rare for the Huron Watershed, but not enough fisherman utilized the creek to make this worth the cost. Last year HRWC staff wrote a creekshed report for Arms Creek, which can be found here along with a clickable and zoomable map.
The Arms creekshed also contains Independence Lake, a beautiful county park located only a few miles from my
house and a spot that my family visits many times during the year. In the summer it is our go-to spot for swimming and waterslides, and in the other seasons we play on the playground and take walks through wetlands and fields. Winter is a great time to visit as the park is all but deserted. Last winter we spent a long time throwing rocks onto the lake and listening to the musical “plunk-plink-plunk-pppppppp” of the rocks echoing and reverberating against the ice.
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/.
HRWC staff frequently presents our work at conferences and convenings both locally and farther afield. We don’t always get around to sharing that information with our followers, but May has been particularly full with such opportunities to share Huron River programs while learning from colleagues and making new connections. Here’s a snapshot of those appearances . . .
RiverUp! @ River Rally
Some river people say that if you can attend only one conference each year, then it should be River Rally. More than 400 members of the river and watershed conservation community gathered in early May at Santa Ana Pueblo, New Mexico, and I was happy to be among them. My session titled “Transforming Your River into Main Street” showcased our RiverUp! efforts to restore and revitalize the river corridor through diverse partnerships, creative financing, and community engagement. Terrific reactions and conversations ensued with attendees from around the country such as Connecticut, Ohio, and California. Rally is hosted by River Network, a network of more than 2,000 state, regional and local grassroots organizations whose primary mission is protecting water resources.
Lakes Monitoring @ Boyne
Paul Steen reprised his trainer role at the annual Cooperative Lakes Monitoring training hosted by the Michigan Lakes and Streams Association at Boyne Mountain Resort, Michigan. The 50 participants, from all over Michigan, attend to improve their skills in various water quality measurements for lakes. The training attracts registered participants in the Cooperative Lakes Monitoring Program (CLMP) and other interested people about how to make water quality measurements and nearshore habitat assessments on their lakes. CLMP is the second oldest lake volunteer monitoring program beginning in 1974 by the state natural resource agency. Check out the inaugural webinar training co-hosted by Paul from earlier this month for details on the CLMP.
Climate Preparedness @ National Adaptation Forum
Rebecca Esselman represented HRWC at the 2nd National Adaptation Forum in St. Louis. While in the Show-Me-State, she participated in a day-long workshop on “Collaborating for Climate Preparedness” where a local non-profit pairs with a local municipality partner to learn about various examples for collaborating. Matt Naud, City of Ann Arbor Environmental Coordinator, joined Rebecca. The National Adaptation Forum, hosted by the Urban Sustainability Directors Network, gathers adaptation practitioners from around the country to foster knowledge exchange, innovation, and mutual support for a better tomorrow in face of climate extremes.

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!
Join a small team led by a Stonefly Hunter who goes in the river so you don’t have to. You will be amazed at the lively creatures living under the ice.
Help HRWC collect data for a long-term study of our watershed. Aquatic insects are sensitive to their surroundings and can tell us about problems in the river and its streams.
Reserve your place at www.hrwc.org/volunteer/stonefly/ No prior experience needed.
This event lasts roughly 5 hours, is FREE and the activities are suitable for all ages, from responsible children to seniors.
Have you ever found yourself in the shower or washing the dishes thinking to yourself, “Self, I wish I knew more about geomorphology.” Well, you are not alone! In fact, HRWC’s geomorphology support group meets in just a few weeks and it’s likely a good idea that you attend.
HRWC’s Measuring and Mapping project teams up all sorts of cool people (like you!) to quantify (really – we’re using this word per it’s definition, not it’s typical public use as of late) how the GEOMORPHOLOGY of our bug collection sites is changing over time.
Now, you’re going to have to trust us that this “data” is “useful” and simply attend the “
training” support group. Well, or you could read Tony, “the volunteer extraordinaire,” Pitts’ writeup on the matter, here.

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.

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.
