Lake D’Arbonne, reservoir in Union Parish, Louisiana

Lake D'Arbonne is a man-made reservoir near Farmerville in Union Parish, northern Louisiana, with a combined estimated area of 15,250 acres (62 km²). A 2,450-foot-long, 54-foot-tall concrete dam built by the Louisiana Department of Public Works in 1961 impounds it, and the lake began to fill by 1963. The larger lower main section is fed by Stowe, Bear and Hurricane Creeks, while the smaller section above the bridge is fed by Corney and Little D'Arbonne Creeks. Louisiana Highway 33 crosses the lake on a bridge named for James Peyton Smith, and Louisiana Highway 2 crosses the northern part on two bridges.

Lake D'Arbonne was first planned in 1957. In 1961 the Louisiana Department of Public Works built a concrete dam 2,450 feet long and 54 feet tall, and the reservoir began to fill by 1963. The Louisiana State Highway 33 bridge over the lake is named for James Peyton Smith, state representative from Union and Morehouse parishes from 1964 to 1972.

The lake takes its name from Bayou D'Arbonne, and the Highway 33 crossing is named for James Peyton Smith, the state representative for Union and Morehouse parishes from 1964 to 1972. The surrounding land is rural and isolated, and the lake is used as a fishing ground, with the adjoining Lake D'Arbonne State Park run by the state of Louisiana as a camping and recreation area.

The lake is open year-round, with warmer months best for swimming and water activities. Visitors should be aware of water level changes and check conditions before boating trips.

The lake's two sections are divided by the Louisiana Highway 33 bridge, named for James Peyton Smith, state representative for Union and Morehouse parishes from 1964 to 1972. The larger main section below the bridge is fed by Stowe, Bear and Hurricane creeks, while the smaller upper section takes in the Corney and Little D'Arbonne creeks.
