What is an off-channel reservoir?

An off-channel reservoir is a water supply lake built next to or near a river.  Off-channel reservoirs are considered by some to be environmentally friendly, lessening the impact on fish and other wildlife by avoiding the need to place a large dam directly on the main stem of the river.

An example of an off-channel reservoir is the Brazos River Authority’s planned and permitted Allens Creek Reservoir, near Houston. For more information about Allens Creek, click here.
