Help us find some special winter stoneflies!

This winter stonefly is one type of insect that you will most likely find!

These underwater creatures elude most predators by growing during the winter months when most fish are more sluggish. They live only in good quality streams so searching for them tells us about problems in the river and its streams.  HRWC does stonefly searches to gauge the health of our streams.

When you sign up to volunteer, you will join a small group of other volunteers to search a selected stretch of stream or river for stoneflies. You will be working with experienced researchers to collect stoneflies. They will also teach you how we determine the health of the stream or river you are visiting. Here’s a personal account with nice photos and a video from the 2021 event below.

Children are welcome to join the search as long as each one is attended by an adult.

DATE The next event will be in January 2023. To get notified for future events, please fill out our Volunteer Signup form here.
TIME There are two starting times: 9:00am or 10:30am. This event takes about 4 hours; approximately half of that is outside.
WHERE Volunteers start HRWC’s office in Ann Arbor, and then go out to stream sites in Livingston, Oakland, or Washtenaw Counties.

January 2021 and 2022- Staying Safe

By collecting stoneflies every year, we gather data to detect trends in water quality health. To keep this effort going during the pandemic, we only invited experienced volunteers to participate in order to avoid a group training event. Check out results from the 2021 search in Kate’s blog here.
