StreamWatch began in 1995 as a comprehensive monitoring program designed to assess the health of Lower Merion’s waterways. Individuals and groups known as StreamKeepers adopt certain sites along Lower Merion’s streams and routinely test the water. In addition to water sampling, each spring we collect aquatic insect larvae to analyze the biodiversity of Mill Creek and publish our findings in the Mill Creek Report.

StreamBank Stabilization Projects
In addition to our monitoring program, we maintain a stream restoration program for township parks like Ashbridge Memorial Park in Rosemont and West Mill Creek Park in Gladwyne. Healthier streambanks mean healthier streams. The vegetated areas along streams, formally called riparian buffers, serve a variety of functions. The plants and trees along riparian buffers not only provide shade to allow for healthier water temperatures, but they also help to stabilize streambanks to prevent erosion. Riparian buffers reduce the amount of stormwater runoff entering the stream and serve as crucial habitat for birds and other streamside wildlife. By restoring and stabilizing streambanks, we can improve the water quality of our streams and allow for more habitat for wildlife.
