WCA -
Rainfall:
Most
of the Water Conservation Areas received between 1.2 and 1.5 of rain, though
WCA-2A had only 0.7 recorded. This amount of rainfall was offset by the
weeks evapotranspiration of 1.5, producing very little change in water levels
for the
Water Conservation Areas:
Water
depths are similar to last weeks (see WCA
stages spreadsheet), ranging from 0.41 in WCA-3A to 2.77 in WCA-2B.
Most water depths are 1 to 1.6 in the WCAs, which are 0.5 to 1 below
last years at this time.
Stages
(WCA Stages spreadsheet) rose somewhat in WCA-1, decreased slightly in WCA-2A
and 2B, and remained overall about the same in WCA-3A. They dropped a
steep -0.24 in WCA-3B (Site 76) but rose 0.11 in Northeast Shark River
Slough. WCA-1 is still within Zone A2, WCA-2 is just below regulation,
and WCA-3A is approximately 1 below regulation (see WCA regulation stages).
Water levels across ENP wetlands
(see ENP Stages pdf) were generally up
again last week. Water levels rose impressively in Shark River Slough
(station P33) after 3.5 inches of rain produced just over a 2 rise. A
similar increase at
Salinity (see ENP salinity pdf) either changed little
or declined slightly across Florida Bay last week. Trout Creek salinity
decreased throughout the week to just below 10 psu at the end of the
weekend. At the platform at the mouth of Little Madeira Bay, salinity
remained near 20 psu. It was very low at the
