Kissimmee Watershed Environmental Conditions – 1/27/09:

 

  • Over the last seven days, the upper Kissimmee Basin received 0.09 inches of rainfall to bring the 30 day total to 0.42 inches (18% of average) and the lower Kissimmee Basin received 0.05 inches of rain to bring the 30 day total to 0.31inches (17% of average) (Daily Rainfall Report 1/26/09).
  • Stage in Lakes Kissimmee, Hatchineha and Cypress is 1.8 ft below regulation schedule and stage in Lakes Tohopekaliga and East Tohopekaliga is 0.6 ft below regulation schedule.
  • On January 27, 2009 the South Florida Water Management District in collaboration with the Florida Fish and Wildlife Conservation Commission treated the final 200 acres of a targeted 7,181 acres of hydrilla in Lake Toho. This treatment started on December 15, 2008, and after a break for the holidays, resumed in early January.  The herbicide used for this treatment was applied aerially due to the massive areas of the lake that had to be covered. Aquathol, a widely used aquatic herbicide was used in liquid and pellet formulations to maximize its effectiveness on hydrilla.   Prior to December 15, 2008, approximately 14,000 acres of hydrilla was present in the lake.
  • Snail kite courtship and nesting behaviors are beginning to be observed around Lake Toho.
  • Discharge from Lake Kissimmee is approximately 324 cfs and discharge at S65C is 362 cfs.
  • The dry season drawdown of the Pool B/C area is on track to reach a low stage target of 33 feet on or around May 15th 2009.
  • Dissolved oxygen concentrations in the Kissimmee River are well above levels of concern.
