NWPS Wilderness Areas Impaired Water Quality: Streams

The graphic on this page shows a summary of inventoried streams on NWPS wilderness areas. Each wilderness area has a row of cells representing each reporting cycle, with each cell shaded to represent the number of assessment units in the wilderness. If inventoried streams are present, miles of inventoried streams is shown in red text inside that cell.

Wilderness areas with no inventoried catchment assessment units are initially hidden, but the table can show all areas or hide empty rows. Click a wilderness name to see inventoried and impaired waters on that wilderness.

Impaired waters are available for wilderness areas managed by the Forest Service, Bureau of Land Management, National Park Service, and Fish and Wildlife Service.
