Measure the size of watershed to help understand sediment in lake?
The Mapping Network created a hydrographic and sediment survey for a property owners association (POA). The main lake inlet has shallow water because sediment settles at the mouth of the stream, creating deltas. The POA installed two sediment basins to capture sediment flowing from the north. However, as shown on the watershed map, much more sediment is flowing from the east (this includes residential areas and a golf course). The POA needed to quantify sediment build-up in their sediment…
