In the Stormwater Management section of the site, you learned about how some of the specific watersheds and their inflows could contribute to the degradation of lake water quality.
Stormwater and the Watershed Homeowner
While the 15 inflow channels identified in the Stormwater Survey drain a significant acreage of the total watershed (400.2 acres – 50.7% combined) and the lake itself represents about 1/3 of the watershed (261 acres), there is still significant area (129 acres – 16.3%) with no appreciable channels but an important contribution of stormwater. On the map in the image to left (click image to enlarge) the shaded red areas represents areas that drain into the lake without major inflows, and primarily through the waterfront properties.
As mentioned earlier, development reduces the amount of permeable soils available to retain stormwater. The wooded areas of Camp Sequassen, Camp Workcoeman and Brodie Park may contribute very little to lake degradation. What does contribute to degradation however are the developed properties along the shoreline. Here it up to the homeowner to do all he or she can to keep storm water on the property for as long as possible and assure that when the water ultimately reaches the lake it is as clear of debris as possible. So there are strategies to reverse the impacts of development. These are so called Best Management Practices.
Here are a few best management practices you could research further to minimize your properties contributions to stormwater runoff.
- Rain Barrels
- Dry wells
- Drainage Swales
- Riparian Buffers (a vegetated planting strip along the shoreline)
- Restoration of native plantings
- Rain Gardens
- Pervious pavement choices
- Proper location of impervious surfaces and reduction where feasible
We’re collecting links to various resources in the section below on Homeowner Best Management Practices you can refer to for more education. But also reach out to me directly and I can refer you to landscape professionals and local residents that can share information on how you can become a stakeholder in implementation of best management practices for your property.

Homeowner Best Management Practices
There are lots of resources on ways to retain stormwater. There are subsurface retention structures (drywells) and surface gardens which can replace lawns (low retention structures) and also collect rain from roofs or driveways. There is also a fair amount of research going into permeable driveways. All of these can and should be considered either with new development plans, or as upgrades to existing developed properties.
