| Following Hurricane Katrina, parishes to the north of Lake Maurepas experience significant population growth, particularly in rural areas with limited water treatment capacity. Nine sites were selected to examine nutrient and algal levels. These sites include three sites where water enters the lake from parishes north and east of the lake and a fouth where water enters from the south. Three sites near the center of the lake where significant mixing of incoming water would have been achieved and two sites where water exit the lake were also monitored. Nutrient monitoring includes phosphate and silicate and nitrate and ammonia levels are being added.Routinely, the pH and temperature are monitored as well. The level of phospahte and pH are somewhat variable where water enters the lake but is relatively consistent at other sites and, compared to historical data available from USGS has not changed since the hurricane. On the other hand, levels of phosphate have increased by 5 - 10 times over historical levels. |
