- Lake Waterford
- Lake Waterford
- Sediemnt Fertilizer
- No Oxygen from plants becuase no sunlight for the Photosynthesis process.
- There are heavy rainstorms at Lake Waterford mid March 2010. There was three inches rain and additional water from the rapid melting snow.
- Dieing Algae decomposing leaving no oxygen for the fish
- The water from the rain went into the lake through run off from the impervious surfaces such as roads and streets. The water carried sediments such was rocks, nutrients such as fertilizer, and other contaminants into the lake.
- Not enough dissolved oxygen for the fish
- The sediment clouds up the water leaving no sunlight for the fish, which is essential for plants that produce oxygen, which is then dissolved into the river. The fish use this oxygen, but without it, the fish won't survive.
- The excess nutrients from the fertilizer in the run off cause algae blooms, which when they die, take up lots of dissolved oxygen in the water for the decomposition process. This leaves even less oxygen for the fish.
- All these contaminiats taking up dissolved oxygen in the water leaves a very low amount for the fish in Lake Waterford. The fish in this lake require 5 mg/L of dissolved oxygen to survive, but with these conraminants affecting that, the fish die.
