Description Monitoring was performed in the Johnson Creek watershed in 1988/89 to assess water quality as related to Class A standards, and to compare conditions to a 1980/81 pre-Best Management Practice study. Water quality in 1988/89 was found to violate Class A standards for dissolved oxygen, fecal coliform, and pH. Fecal coliform, nitrate and total phosphorus concentrations increased significantly between thepre and post-BMP implementation studies, but turbidity decreased. It appears that manure continues to reach creeks in the watershed regardless of the BMPs; this may be predominately due to improper management techniques and/or non-participating farms.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
