The Lake Somerville Trailway connects Birch Creek and Nails Creek units via trail around the west end of Lake Somerville. The Trailways 26 miles of interconnected trails and loops let you explore the shoreline.

Those miles of trail cross through yaupon, post oak, hickory, blackjack oak and water oak forests, and pass scenic overlooks and water crossings.

All trails are open to hikers, mountain bikers and horseback riders.

Lake Somerville has over 11,000 acres of water to explore by motorized boat, kayak or canoe. Birch Creek and Nails Creek have boat ramps.

Three main creeks either run through or border the park units, all of which drain into Lake Somerville. Nails Creek flows along the southern border of the Nails Creek Unit. Yegua Creek enters the lake on the north side of Nails Creek Unit. Birch Creek forms the east border of Birch Creek Unit.

Flag Pond and numerous other duck ponds, marshes and bogs are between the two parks, at the western edge of the lake.

The land in the park is gently rolling, with a wide variety of trees and spectacular wildflowers in the spring.

The U.S. Army Corps of Engineers began building Lake Somerville in June 1962. Deliberate impoundment of water began in January 1967.

The dam is located on Yegua Creek, 20 miles upstream of where it joins the Brazos River, and about two miles south of Somerville. The lake covers 11,630 acres and has an 85-mile shoreline. Its main purposes are flood control, municipal water supply and recreation.

TPWD leased the complex from the federal government in 1969 and opened it in 1970. TPWD manages the Somerville Public Hunting Land under a license agreement and in cooperation with the U.S. Army Corps of Engineers.

Flag Pond is a 350-acre impoundment in the Yegua Creek watershed along the Trailway. A private hunting club originally developed the pond in 1926.

Enjoy, but do not disturb historical places. If you find an artifact, leave it in place and let park staff know.
