The area is part of the Eldorado National Forest, which includes the famed gold mining territory of the 1800s. Protected remnants of the days of the California Gold Rush are all around the region. The climate is similar to that of the Mediterranean, with warm, dry summers and cold, wet winters. An abundance of wildlife can be found within the Sierra Nevada Range, including black bears, mule deer, bobcat, gray fox, bighorn sheep, pikas, martens and a variety of squirrels. Several species of reptiles, amphibians and birds also inhabit the area. Recreation The Union Valley Bike Trail spans 4.8 miles with an easy climb of 300 feet. The trail connects campgrounds on the east side of the lake, from Jones Fork Campground to Wench Creek, and is open to hikers and bikers. The Bassi Falls Hiking Trail is also worth exploring. Anglers seek rainbow, brown and mackinaw trout or kokanee salmon. The reservoir also offers opportunities for swimming, water skiing and boating. A boat ramp and boat trailer parking are provided at this campground.
