Pay attention to what you are taking out help a flowing stream, and don't remove every thing. Shady pools form around logs and rocks. A dumped tree stump may be the per- fect perch for a river otter. The bedsprings may provide a hiding place for some unseen creatures. It might be more destructive to disturb the stream bottom than it would be m. to leave old junk in place. out how deep you the"garbage" you want to remove is buried. e If it is more than 50 percent buried, consider it part of the stream habitat.
