Black Lake, reservoir in Louisiana, United States

Black Lake is a large reservoir in Natchitoches Parish that serves fishing and recreation. The water features natural shorelines with trees leaning over the surface and open views where local fish populations thrive, making it accessible for both shore and boat-based activities.

Black Lake is a dammed reservoir, not a natural lake: the Alan Chiverly Dam, built in 1934, holds its water between Black Lake and Saline Lake before it drains toward the Saline bayou. Its name dates from the French Louisiana period, when the lake and its bayou were called lac Noir; the toponym was anglicised to Black Lake during the 20th century.

Louisiana Highway 9 crosses the lake, with Black Lake on the west side and Clear Lake on the east; Road 1226 also runs between the lakes. Boat launches and campgrounds serve fishing and boating, and Bell's Camp, founded in 1936, is still run by the founders' daughter. Boats should stay in the dredged channels or risk grounding on tree stumps.

The lake undergoes controlled water level reductions that expose large shore areas and reduce invasive plant growth, mimicking natural lake cycles. This intentional management approach supports healthier fish populations and improves access for visitors.
