Kissimmee Watershed Environmental Conditions – 07/15/08:

·        Over the last seven days, the upper Kissimmee Basin received 1.70 inches of rainfall to bring the 30 day total to 7.37 inches (104% of average), and the lower basin received 1.54 inches to bring the 30 day total to 9.81 inches (147% of average) (Daily Rainfall Report 7/14/08).

·        All upper basin lakes remain below regulation schedule except for Lakes Hart and Mary Jane which are at regulation schedule stage.

·        In the upper basin, snail kites continue to nest on East Lake Toho, Lake Toho, and Lake Kissimmee.  

·        Flow is approximately 200 cfs at S65 and 800 cfs at S65C.

·        Water levels within the Kissimmee River Restoration Project area have been rising and falling in response to rainfall events.  Last week’s rainfall and lack thereof caused water levels to fluctuate by approximately 1.5 feet within the restoration project area.   

·        Over the past week, dissolved oxygen concentrations in the river channel of the Kissimmee River fell below thresholds of concern (2.0 mg/L).  Concentrations ranged from 0.8 mg/L to 2.1 mg/L and averaged 1.4 mg/L.  Low DO levels are thought to be a result of high water temperatures and biochemical oxygen demand from local inflows.
