Changes to receiving water bodies following Best Management Practices project (BMP) implementation were evaluated using the Environmental Integrity Index (EII). Data from five wet ponds and one channel restoration project were used. Changes in the six EII sub-indices (water quality, sediment quality, contact recreation, non-contact recreation, habitat quality and aquatic life support) were generally positive except for habitat quality, which declined initially but tended to recover. Water quality through wet pond sites improved by an average of 7%, and the channel erosion site improved water by 18%. Additional data collection is needed to strengthen conclusions.


This report mentions how the water quality of upstream Waller Creek can affect downstream sites.
