I have access to a tiny ice cold creek on private property. About 6 or7 years ago my uncle found that it was loaded with tiny brookies and built some nice habitat for them. there are two holes dug out with a bucket loader that hold the majority of the fish through the winter and summer. the fish are growing much larger some into the 10 to 11 inch range. the man made pools are starting to get choked with leaves and i want to try to clean them out with out hurting the population currently in the creek. when the original work was done it took a couple seasons for a noticable population to return. I was wondering if anyone has any knowledge or experience with this sort of situation.
