The Olentangy River’s water level is controlled by the Delaware Dam which the Huntington (West Virginia) District of the U.S. Army Corps of Engineers oversees. The construction of the dam was completed in July of 1948. The amount of water released (in cubic feet per second (CFS)) varies year round, based on recent rainfall and the season. The Delaware Lake is maintained for a summer pool and winter pool, seasonally, for recreation purposes and flood control. More information on the Delaware Lake can be found here. Always check the current river levels using the USGS data before entering the Olentangy.

Central Ohio Blueways
The Mid-Ohio Regional Planning Commission (MORPC), in partnership with local communities, parks districts, and grassroots organizations — provides residents and visitors with information on where they can safely and legally access the water for paddle sports in Central Ohio’s neighborhoods.
