Ater more than five years, Turlock Lake State Recreation Area will once again be open to the public. Stanislaus County, Turlock Irrigation District and California State Parks announced this week the approval of an agreement to re-open and operate Turlock Lake thanks to nearly $8.2 million in funding from the state of California for facility improvements and one-time start-up costs. … Turlock Lake, with 26 miles of shoreline, is owned by Turlock Irrigation District and sits on the south side of the Tuolumne River, along the rolling foothills of eastern Stanislaus County, about 25 miles northeast of Turlock.
