The GBP monitoring plan is intended to provide the data necessary to evaluate the degree to which the commitments of the UA, EA, Supplemental EA, FONSI and consensus letter have been accomplished. To this end, flow, water quality, sediment, biota, toxicity and bioaccumulation monitoring have been identified as the tools for assessing the impacts of using a portion of the SLD to convey agricultural drainage water around the North and South Grasslands wetland areas.
