Short 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 the pre 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.
