Gathright Dam release to increase water flow

NORFOLK, Va. (AP) -- The U.S. Army Corps of Engineers plans a controlled release from the Gathright Dam on Tuesday to increase the Jackson River's water flow.

The corps wants to determine whether controlled releases effectively remove algae and improve water quality in the lower Jackson River.

Beginning around 6 a.m. Tuesday, water gradually will be released until the flow peaks at 3,500 cubic feet per second. Normally, releases at this time of year are at a constant flow and height.

The corps says in a news release that the maximum surge will last two hours. Then the flow will gradually fall to 250 cubic feet per second.

Controlled releases also are planned in August, September and October.
