Re: Cleaning up Streams
In our area (Centre County) there is a massive stream cleanup every April. This was originated by Trout Unlimited, but in recent years it involves all sorts of community groups, the Scouts, service organizations, local townships,etc. It's now coordinated by Clearwater Conservancy.
There are similar community stream cleanups in many areas in PA, usually once a year, usually in the spring.
One important note about stream cleanups. Remove trash, that's the whole idea. But do NOT remove downed trees, logjams etc. in the streams. That "large woody debris" or "coarse woody debris" as the scientists call it, is very important in creating pool and overhead cover habitat for fish.
In the past, it has been the custom in many areas to remove large woody debris, to great harm to the stream habitat and trout populations.
