The Mapping Network created a hydrographic and sediment survey for a property owners association in Cleveland, Ohio. The main lake inlet has shallow water because sediment settles out at the mouth of the stream, creating deltas. These deltas impede fish migration, act as bedding areas for nuisance aquatic species, hinder recreational activities such as swimming and boating, and force property owners to extend their docks.
The POA installed two sediment basins to capture sediment coming from the north but as you can see from the watershed map, much more sediment is arriving from the east (this includes residential areas and a golf course). The Mapping Network sampled the sediment structure and mapped the sludge thickness to help the client in the dredging bid process. Part of the report included understanding sources of sediment and how activity within the watershed will ultimately affect the lake. Below are maps showing the current water depth, sediment thickness, and total watershed.
