Volunteers braved the snow and cold to search local streams for winter stoneflies on January, 21st as part of CRWC’s annual Stonefly Search.
The stonefly is an aquatic insect that lives in streams and rivers during its juvenile life-stages. The insect is very sensitive to disturbance in the stream or changes in water quality, and their presence in a river indicates good water quality.
There are a variety of different stoneflies that can inhabit a river, but two unique types of stoneflies have adapted to be more active and emerge as adults during colder months:

Below are locations and results of the winter stonefly search. CRWC aims to sample more locations each year to increase the amount of data and information collected on these unique organisms. More information will help us further understand the conditions of our streams throughout the watershed.
