Drop off used motor oil at gas stations or garages that recycle. Motor oil is extremely toxic. Never pour used motor oil, leaves, lawn clippings or any other waste material into storm drains. Not all plants are bad. Vegetation along stormwater ponds, including weeds, helps absorb nutrients and pollutants that might drain into the Bay.
Good plants make water bodies a better place for fishing.
Add swales and berms to your pondside yard. A swale is a small dip in the slope of your yard. It catches storm water and filters it through the ground before draining into the pond. A berm is a small hump next to the swale. A berm helps hold water in a swale until it seeps into the ground.
