Kissimmee Watershed Environmental Conditions – 04/15/08

 

·        Over the last seven days, the upper Kissimmee Basin received 0.01 inches of rainfall to bring the 30 day total to 4.03 inches (142% of average), and the lower basin received 0.03 inches to bring the 30 day total to 4.20 inches (163% of average) (Daily Rainfall Report 4/14/08).

·        The large rainfall reported last week resulted in stage reversals in several lakes in the upper basin.  The largest reversal was 0.75 ft in Lake Toho, which has the potential to impact on apple snail reproduction and nesting by wading birds and snail kites. 

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

·        A whooping crane continues to nest on Lake Kissimmee.

·        The discharge from Lake Kissimmee (S-65) continues at approximately 1500 cfs to provide flow to the Kissimmee River and to allow a gradual water level recession on the floodplain.  No other releases are being made in the upper basin.

·        Flow has been reestablished to the Kissimmee River for 265 days (S-65 re-opened on 07/18/07).

·        The inflow from the upper basin continues to inundate a portion of the floodplain in the Phase I area of the Kissimmee River Restoration Project. 

·        Dissolved oxygen concentrations in the river channel of the Kissimmee River ranged from 1.8 mg/L to 4.7 mg/L with an average of 3 mg/L.

  • Hydrilla treatment began in Lake Cypress last week and continues this week.  It is anticipated that releases from Lake Toho will resume on Thursday (April 17).
