RESTORING STREAM INTEGRITY THROUGH WATERSHED SCALE STORMWATER MANAGEMENT.
A leading cause of degraded stream integrity (chemical, physical and biological) comes from poorly mitigated, or completely un-mitigated, storm water runoff. These altered flow regimes have accelerated stream bed mobilization and bank erosion rates, leading to losses of biodiversity and shifts in aquatic community structure, as well as damage to nearby infrastructure (roads, utilities, etc.) and private property. Recognizing these impacts, SD1 of Northern Kentucky, the regional stormwater management utility, embarked on a nearly decade long assessment that identified relevant flow thresholds (Qcritical) to local receiving streams. Using this information, pilot studies are currently underway that attempt to restore natural hydrology through the retrofitting of existing storm water management facilities (e.g. detention ponds). Through relatively simple optimization of the outlet control structures associated with these facilities, flow rates can be controlled to reduce the destabilizing impacts to receiving streams, as well as the potential restoration of base flows. This presentation will highlight the progress made to date, as well as discuss the preliminary in-stream results.
