StreamWatch began in 1995 as a comprehensive monitoring program designed to assess the health of the waterways in and around Lower Merion. Individuals known as StreamKeepers visit specific sites along local streams each month to make observations and track changes. Conservancy staff use a collect quarterly water samples to further assess stream health. In addition to chemical testing, we collect aquatic insect larvae each spring to analyze the biodiversity of Mill Creek. A summary of our findings is published in our 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 lead to healthier streams. The vegetated areas along streams reduce the amount of polluted stormwater entering the stream, provide shade to allow for healthier water temperatures, stabilize streambanks to slow soil erosion, and serve as crucial habitat for wildlife. If you live along a stream or volunteer in a park with a stream running through it, you can create or improve your riparian buffer by planting trees and other native vegetation within 50 feet of the stream banks.
