Pleasant Hill Lake (Richland County)
eBird Bar Charts by Season
The western section of Pleasant Hill Lake is in Richland County. The eastern section of Pleasant Hill Lake is in Ashland County.
The Muskingum Watershed Conservancy District (MWCD) owns Pleasant Hill Lake. The lake was constructed in 1938 by damming the Clear Fork Branch of the Mohican River. The lake was originally constructed primarily for flood control in the Muskingum River watershed. Today, recreation is one of the biggest public benefits. The ODNR Division of Wildlife manages the lake under an agreement to provide public fishing and hunting.
The Clear Fork River empties into the western end of the lake. This western end of the lake is shallow with most of the area under less than 10 feet of water. The middle section of the lake gradually slopes to a depth of 20 feet. At that point, the lake makes a sharp bend to the south and the basin changes to a steep-sided, deep, gorge-shape with a maximum depth of 35 feet.
The portion of the lake that runs from west to east is shallower and warmer. The bottom of that part of the lake is composed of mud (clay and silt), except along the shorelines where wave action has exposed sand and small gravel. The lower portion of the lake, running north to the south, is deeper, slightly cooler, and has larger boulders along the shoreline. Vegetation is confined to the shoreline of the western end of the impoundment and is controlled by water clarity. The transparency of the water varies from about 6 inches in the springtime to 4 feet later in the season, when the sediment has settled.
