Calling All Scientists!


The Conservancy needs your help this coming spring to monitor and protect our local streams.  We have both one-time and monthly volunteer opportunities available.  Our volunteer StreamKeepers collect data each month at pre-assigned locations through the Mill and Cobbs Creeks Watersheds.  StreamKeepers are our eyes and ears on the stream to monitor improvements or declines water quality.  If you love the outdoors and are drawn to water, this is a great way to make a difference in your own backyard.

Sign-up today for one of our spring one-time sampling dates, or consider becoming one of our StreamKeepers.
