Lake Clementine features a 155-foot man-made dam, built in 1939 to control mining debris. The area offers a scenic hike with a 4.5-mile round trip trail, passing under the Foresthill Bridge, the tallest in California. The reservoir is part of the Auburn State Recreation Area, known for its natural beauty and recreational opportunities. It is particularly noted for its picturesque waterfall created by the dam, making it a popular spot for photography.
