WCA - Everglades Conditions Update (August 7, 2007)

 

 

Rainfall:

Total precipitation (in inches) for the week, starting in the North, was WCA1=1.7; WCA2A=1.0; WCA2B=0.6; WCA3A=1.7; WCA3B=0.4; ENP=1.0 inches (see attached Raindar.gif). The regions with the lowest rates of re-hydration were WCA-3B (-0.06’) and ENP (-0.12’) (see attached WCA Stages.xls).

 

Water Conservation Areas:

Rainfall exceeded evaporation (see SRS.pdf) for most regions and this resulted in net increases in water depth for all regions with the exception of WCA-3B (-0.06’).  Marsh depths now range between 0.62 ft (6-3 gage) and 1.56 ft. (6-5 gage) (Note: Gage 99 is not considered a marsh gauge.), and continued increases are seen a good thing for the environment.  In terms of the Regulations Schedules; WCA-1 is at Regulation, WCA-2A is above Regulation, and WCA-3A is below regulation (see WCA Regulation Stages.doc).

 

Everglades National Park:

No data was received from ENP since last Tuesday.  We are using USGS & SFWMD data to provide an update for conditions in this area and will try to resolve data issues from Park by next week.  Overall the Park experienced a net loss of water depth of -0.12’.  Salinity continues to remain seasonably low & stable across FL Bay.  Trout Ck. represented the 1 exception, having experienced a mid-week flow reversal that pushed FL Bay water northward and increased salinity concentration in the creek upwards of 20 psu before dropping to a seasonal level (~ 5 psu) over the weekend.  Salinity at the mouth of Taylor River was generally remained below 10 psu for another week.  Salinity concentrations in the Taylor River ponds held very low all week (close to 1 psu in Pond 5).  In the north-central Bay area of McCormick Ck. salinity rose briefly mid-week into the mid-20s before dropping back towards 20 psu by the weekend.
