A typical candidate watershed site for rehabilitation was constructed between the late 1950's to the middle 1960's. When the projects were planned the majority were in a rural setting. Many dams originally constructed as low hazard are now classified as high hazard as a result of downstream urbanization. These dams must now be upgraded to meet high hazard criteria.
WRAT is participating in the planning of the rehabilitation of some sites by using a calibrated SWAT model to determine sedimentation from the watershed with projected land use changes.
