During the spring, summer and fall of 2004, a limnological survey of Silver Lake was conducted. The purpose of the survey was to update the status of Silver Lake. Some of the questions being asked were as follows. Was the lake highly productive? Were the bottom layers of the lake devoid of oxygen? Was phosphorus being released from the sediments into the water column? Were there algal blooms? What might be the cause of them? Were there blue-green algae present? Were algal toxins present? When? Monitoring was designed to take samples only during the summer period with depth to minimize cost. We decided to sample an extra week in the fall because of the blue-green algae bloom that was observed during September of 2004
