LINCOLN, Neb. (AP) — Nebraska state troopers are planning to patrol Lancaster County lakes to help reduce alcohol-related accidents.

The special enforcement will take place primarily on weekends. The effort will begin Friday and run through Aug. 14.

The troopers will set up high visibility patrols and DUI checkpoints at county recreational areas.

The effort follows Sheriff Terry Wagner’s calls to ban alcohol at a county lake. Authorities say about 700 partiers converged at Branched Oak Lake during the Memorial Day weekend and trashed the beach.

Wagner says he welcomes the increased police presence.

The patrol will pay for the special enforcement with a $3,000 grant from the Nebraska Office of Highway Safety.
