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.
