Stream Stewardship: Instream

The purpose of this page is to discuss common practices that people undertake in streams and their effects on the stream system. Please view our Principles of Stream Stewardship to read about the concepts we recommend keeping in mind prior to undertaking a stream project. Additionally, you will also find alternative stream restoration solutions to traditional bank hardening techniques, contact information for assistance and brief information about what people can and can’t do in Catskill streams.
