General Information

Delaware Lake is part of a system of dams that reduce flood stages in the Olentangy, Scioto, and Ohio River Basins; benefiting communities and agricultural lands between Delaware and the Gulf of Mexico. Delaware Dam and Reservoir is located 32 miles above the mouth of the scenic Olentangy River, a tributary of the Scioto River, near Delaware Ohio. Authorized by the Flood Control Act of 1938 for the purposes of flood reduction, low-flow control for pollution reduction and water supply, recreation and fish and wildlife management, the project was constructed between 1947 and 1951 at a cost of $ 4,307,000. The project was constructed and is operated by the U.S. Army Corps of Engineers, Huntington District. The Dam is a rolled earth fill type with a concrete gated spillway section. At a length of 3 ½ miles and a height of 92 feet, Delaware Dam controls a drainage area of 386 square miles through the use of five gated sluices and six 25 foot by 32 foot tainter/radial gates. Golden Age and Golden Access passports may be used for a 50% discount at all Federally operated areas where a fee is charged.
