The purpose of the Upper Scioto Watershed Pilot Project is to test our ability, working in partnership with the Ohio EPA and other partners, to manage and document environmental improvements at the 8 digit HUC level. The traditional water quality management approach consisting of a number of pollution reduction efforts will not restore water quality in the Upper Scioto Watershed. The passive in channel restoration associated with the planned and ongoing pollution reduction efforts is insufficient to provide for full biological recovery and met water quality standards. The pollution control efforts must be augmented to provide for full biological recovery or a TMDL will be required. Integrating watershed management with dam removal will provide the critical aquatic restoration needed for full biological recovery. This project will focus intensive efforts in the Olentangy sub watershed, within the Upper Scioto 8 digit HUC watershed. In order to document environmental improvements at the 8 digit HUC level a hierarch monitoring approach for the Upper Scioto Watershed is being implemented. This effectiveness monitoring is to document the impact of the Olentangy activites at the 8 digit level by employing a nested pre/post design with multiple samples in between to determine if water quality changes are going in the right direction. This effectiveness monitoring design allows us to answer; "What is the change in conditions and direction of the trend in water quality at the 8 digit HUC. level?" The Olentangy watershed was selected based on the probability of rapid results, potential leveraging of a variety of restoration and protection resources, and for the strategic significance within the larger 8 digit HUC watershed.
