Kissimmee Watershed Environmental Conditions – 11/18/08:

  

·        Over the last seven days, the upper Kissimmee Basin received 0.50 inches of rainfall to bring the 30 day total to 1.35 inches (53% of average) and the lower basin received approximately 0.10 inches to bring the 30 day total to 0.80 inches (33% of average). (Daily Rainfall Report 11/17/08).

·        Stage in Lakes Kissimmee, Hatchineha and Cypress is now 1 ft below regulation schedule and stage in Lakes Tohopekaliga and East Tohopekaliga is approximately 0.5 ft below regulation schedule.

·        Discharge from Lake Kissimmee remained at approximately 300 cfs and discharge at S65C increased from 180cfs to approximately 400 cfs.

·        Water depths on the floodplain currently range from 0.5 to 1.0 ft in the south end of the restoration area and in low-lying areas see graphic

·        Stage in C-38 north of the current backfilling project is approximately 7-8 ft higher than south of the backfilling due to water being conveyed onto the floodplain around the active backfilling in an effort to control turbidity.  The contractor expects to widen/clean out the flow-way around the construction area and decrease the head difference soon (see Contract 13b.jpg attached).

·        The post-Tropical Storm Fay recession rate on the floodplain is approximately 2.2 ft/30 days, about twice as fast as our target rate.

·        From 11/4/08 to 11/18/08 dissolved oxygen concentrations in the Kissimmee River ranged from 5.0 mg/L to 7.9 mg/L and averaged 6.4 mg/L.
