Kissimmee Watershed Environmental Conditions – 09/25/07

 

·        The upper Kissimmee Basin received 2.18 inches of rainfall over the last 7 days to bring the September total to 4.31 inches (88% of average) and the lower basin received 1.64 inches to bring the September total to 5.38 inches (112% of average) (Daily Rainfall Report for 09/25/07).

·        Stages in most of the upper basin lakes have been stable over the last seven days.

·        Snail kites continue to nest on Lake Tohopekaliga but activity has slowed.  There are 11 active nests including one that is in the early stages.  Many non-nesting snail kites are still using the area (USFWS September 21, 2007). 

·        Flow has been reestablished to the Kissimmee River for 69 days (S-65 re-opened on 07/18/07).  Discharge at S-65 continues at approximately 500 cfs

·        Increased discharge at S-65C indicates increased basin runoff.

·        The concentration of dissolved oxygen in the river channel has remained above thresholds of concern for most of the last week with mean daily values ranging between 1.3 mg/L and 4.2 mg/L.  On one day the mean value fell below 2 mg/L.  on another day, the minimum fell below 1 mg/L for approximately 1 hour but the average for that day was above 2 mg/L.  The lower values are likely due to cloudy days and local runoff causing increased organic loading.
