This layer shows the quality of habitat surveyed by Delia Malone on selected reaches in the Roaring Fork Watershed. This data is intended as a reference for future research and planning, site specific conditions may vary. Strahler Steam Order numbers are also given for each river reach.

River Watch Sites

This layer was digitized in 2015 for the HRS Board using data from the Roaring Fork Conservancy.
