Directions: Beardsley Reservoir is about 33 miles east of Sonora on Highway 108. Take Beardsley Road (5N02) about 7 miles west to the lake.
Beardsley Lake contains both Browns and Rainbows. It is within a steep canyon of the Middle Fork of the Stanislaus River at 3,400 feet. The lake was created by a rock-filled dam in 1957 and is subject to numerous drawdowns throughout the year which affects the fishing. The fishing season is open year-round for this lake although the access road is often closed during the winter. About 35,000 rainbows and browns are planted each year in the 12-14 inch class. However, when conditions are right, the lake offers many trophy sized trout, the lake record is 10 lbs. 4 oz for Rainbow. Locals like to float tube this lake during the early Spring and late Fall, especially when the lake levels are low and the boat traffic has reduced. The areas near the dam are favored working the steep shorelines with streamer patterns. Expect strong, windy conditions on a daily basis in the afternoon. The afterbay below the dam also offers excellent fishing with a float tube throughout the year. A 4 mile trail follows the river from the afterbay to Sand Bar Flat. This stretch of water is a classic tailwater with trophy-sized browns and rainbows. The river consists of large boulders and deep pools with scattered pocket waters.
