Conowingo Reservoir is a 9,000-acre lake on the lower Susquehanna River behind Conowingo Dam, the largest dam in Maryland, on the line between Harford and Cecil counties.
We rent MasterCraft wakesurf boats, Sea-Doo jet skis and water toys on Conowingo Reservoir, and everything is ready for you at the lake. Add a captained charter with lessons for every level.
From the dam, the lake stretches north past the Pennsylvania line toward Holtwood Dam, and it's known for some of the best smallmouth bass fishing in Maryland.
