The State of Maryland purchased the lake in 1955 from the Smithville Farm Machinery Company. Because of its long narrow shape, Smithville Lake does not appear as large as the 43 surface acres it measures. Maximum depth 8ft, and the average is roughly 3ft. The lower two-thirds of Smithville Lake consists of outstanding fish habitat. A severe ice storm in the early 1990's snapped off tree tops which fell into the lake, providing excellent fish habitat.
Fish also inhabit the rooted aquatic vegetation.
Quality fishing for both of these species exists within the lake. Restrictions - Gas motors over 10 horsepower are not permitted for use. Electric trolling motors are preferred. Camping and swimming are not permitted.
