For over 50 years, the NRCS has assisted in the construction of over 11,000 small
watershed dams. These dams provide millions of dollars in benefits each year by providing flood
control, wildlife habitat, recreation, irrigation and livestock water, and municipal and rural water
supplies. While many of these dams continue to adequately provide these benefits, it is currently
estimated that nearly half of the NRCS dams will surpass their planned service life in the next 10
years. For these structures to continue to function properly and safely, rehabilitation is required. If
ignored, these dams could place life and property at risk.
