Multiple Years of Monitoring Before and After BMP Implementation

In the Rock Creek (Idaho) RCWP project, irrigated cropland and streambank erosion were causing high sediment loads in Rock Creek, impairing salmomid spawning, contact recreation, and fishing. Ten-year monitoring encompassed pre-, during-, and post-BMP implementation periods in multiple subwatersheds and on Rock Creek.

Through its water quality monitoring program, the Taylor Creek - Nubbin Slough (Florida) RCWP project documented a greater than 50% reduction in total phosphorus concentration leaving the watershed. At least five years of biweekly water quality monitoring was collected for both the pre- and post-BMP periods.
