WCA – Greater
Everglades Conditions
Weekly Update – October 27, 2009
Rainfall:
Rainfall
increased again last week in the Greater Everglades (see Raindar image and
below). It was generally under an
inch except in WCAs -2A (1.03”) and -2B (1.46”), with heavier distributions to
the east.
Rain:
WCA-1: 0.78
in
WCA-3A: 0.74 in
WCA-2A: 1.03
in
WCA-3B: 0.94 in
WCA-2B: 1.46
in
ENP:
0.66 in
Water Conservation Areas:
This week’s pan evaporation of
1.24” (see srs pdf)
exceeded rainfall in most conservation areas (see WCA Stages spreadsheet and
below), but the stage declines were much lower than last week and stages rose in
other locations. Stages declined in WCA-1, -2A, and
-3A, but rose in WCA-2B, -3B, and northeast Shark River Slough.
Stage Change:
WCA-1: -0.03
ft
WCA-3A: -0.08 ft
WCA-2A: -0.11
ft
WCA-3B: 0.05 ft
WCA-2B: 0.21
ft
NESRS: 0.10 ft
Water depth changes are mixed
across the region (see WCA Stages spreadsheet). They are continuing to
drop at gage 65 in southern -3B, the only gage where
tree islands occur and stages exceed 2.5 ft. Marsh water stages in WCA-1
are 0.5 ft below regulation in zone B and have remained steady over the
week. Stages in WCA-2A remain 0.5 ft above regulation and are rising.
In WCA-3A, stages have declined rapidly and are now slightly below regulation
(see Reg schedule).
Water depths in the conservation
areas show overall declines relative to a month ago (see Water depths
map). Greater Everglades depths are lower now
than they were both a month ago and a year ago (see SFWDAT Depth Diffs map).
No fires were reported this week
in the Greater Everglades.
Everglades National Park (ENP) and Florida Bay:
Rainfall was light across ENP wetlands and Florida Bay last week. Basin-wide amounts were 0.66” for the ENP and 0.58” for the C-111 basins (see Raindar).
There is no report for the Park and for Florida Bay this week.
