The Ocklawaha River originates at the north end of Lake Griffin in Lake County. The upper reach is largely channelized but is in a natural condition for most of its length. Rodman Reservoir is a 16 mile impoundment lying between Highway 316 near Ft. McCoy to Highway 19 near Palatka. The river is again natural from the Rodman Dam to its confluence with the St. Johns River near Welaka.
Public boat ramps are at Moss Bluff off Highway 464, Ray-Davidson Park at Highway 40, Gores Landing off CR 415, Eureka East and West on Highway 316, Orange Springs, Kenwood Landing and Hog Valley on Rodman Reservoir, Rodman Dam off Highway 19 and Highway 19 south of the barge canal.
