Deputies stepped up enforcement Sunday to stop nudity at a Lake Tahoe beach after Washoe County Sheriff’s Office deputies saw alleged lewd acts Saturday at the beach.  A Washoe County deputy on Saturday from a boat told people at Secret Cove that indecent exposure is a sex crime and nude sun bathing is not allowed in public places by Nevada law. A video of part of the interaction was posted to Facebook. When asked about the lewd acts, Washoe County Sheriff’s Office spokesman Bob Harmon said men were seen sunbathing nude and making inappropriate and lewd gestures.
