Unlike suspended sediment in stormwater, the removal of visible pollutants is not regulated by state code. However, aesthetics of a waterbody from the shoreline can be an important part of public perception of water quality. A waterbody may be considered to have "good" water quality, based on nutrient levels and other consituents, but if there is trash and weeds along the shoreline, the majority of the public will have a negative perception.

Since 2008, the City of Madison has had a contract to collect trash along the Monona Bay shoreline on a regular, monthly basis and after each major (1.2+ inches) rain event. The contract runs from April through November. Trash collected is 1-inch or larger.
