Lakes Smokehouse and Keene are among a cluster of small lakes in southeastern Lake County. The physiography is described by Brooks and Merrit (1981) as The Gap (see Fig. 8, Regional Geology), an area of lower elevation, about 25 to 37 m (85 to 120 ft) between the Sugarloaf Mountain region and No Name Ridge. The lower elevation is a result of increased erosion of the underlying limestone. The Gap and the flanking highlands are part of the Lake Wales Ridge, which is the topographic crest of Central Florida (Brooks and Merrit, 1981). The Ridge is characterized by residual sand hills, relic beach ridges and paleo dune fields. The topography on either side of the ridge has been reduced to the water table, forming Green Swamp about 5 km (3 mi) to the southwest and Sawgrass Bays to the southeast. Lake levels for Lakes Keene and Smokehouse, 3 km (2 mi) in December of 1995 were approximately 34 m (110 ft) and 35 m (114 ft) NGVD, respectively. Lake Keene, the larger of the two, is oblong, with a perimeter of 2.4 km (1.5 mi) and a surface area of about 0.2 km2. Smokehouse Lake is roughly circular (roundness of 0.92) with an area of 0.1 km2 and a perimeter of about 1 km (0.6 mi). The lake is connected by surface drainage to other small lakes which drain into Sawgrass Lake to the northeast.
