The Water Control Manual, or WCM, provides operational parameters defining how and when water is stored and released. These include a schedule of releases, conservation pool levels to be maintained during non-flood or drought conditions, and downstream water level constraints. Lake Ashtabula is authorized for flood control and water supply. It is also authorized for the additional purposes of pollution abatement and recreation and fish and wildlife management.
The US Army Corps of Engineers has reviewed the existing WCM and is proposing to revise operating parameters to better serve the project purposes. This review resulted in the creation of a draft Decision Document with an Integrated Environmental Assessment. The selected plan does not involve any modifications to the dam structures, but rather is evaluating how to best manage water using the existing project infrastructure.
