...Drought Improvements Across South Texas...

SYNOPSIS...

The Labor Day weekend brought additional heavy rain to South
Texas, with widespread amounts of 1 to 3 inches. Locations across
Webb County, Victoria County, and counties along the coast
received nearly 4 to 6 inches of rain. All this rain in addition
to past rains has led to great improvements in the drought status
across South Texas. The September 6th Drought Monitor shows the
majority of South Texas in either no drought or Abnormally Dry
(D0). What is left of the drought is Moderate Drought (D1) across
the far northern portion of Victoria County, as well as areas
generally near and west of US Highway 83. Severe Drought (D2) also
exists across the western tip of Webb County, generally near and
west of Las Tiendas.

SUMMARY OF IMPACTS...


WATER RESTRICTIONS

Best practices for Water Conservation:
1. Only water landscapes to maintain adequate soil moisture.
2. Only water lawn if rainfall has not fallen in 1-2 weeks.
3. Use a sprinkler which makes larger water droplets.
4. Turn sprinklers toward the lawn and not the pavement.
5. Avoid watering on windy days.
6. Turn soaker hoses holes downward, facing the grass.


CORPUS CHRISTI –  Stage 1 Drought Restrictions.


http://www.cctexas.com/conservation
http://portlandtx.com
http://inglesidetx.gov
www.nueces-ra.org

The city of Corpus Christi draws its water from both Lake Corpus
Christi and Choke Canyon Reservoir. When the combined water
capacity of both of these reservoirs falls below 40%, Stage 1 in
water restrictions begin. The current combination capacity as of
September 8, 2022 is 47.6%.


VICTORIA – Stage 1 - Voluntary Water Conservation

www.victoriatx.org
www.waterwatch.usgs.gov/?m=real&r=tx

The city of Victoria draws its water from the Guadalupe River as
well as Canyon Lake upstream along the Guadalupe River. When the
Victoria USGS (United States Geological Survey) river gauge on the
Guadalupe falls below normal, Stage 1 in water restrictions
begin. As of September 8, 2022, the Guadalupe River is at below
normal flow.


LAREDO – Stage 2 - Mandatory Water Conservation

http://www.cityoflaredo.com/utilities/water-conservation.html
www.waterdatafortexas.org/ reservoirs/individual/amistad

The city of Laredo draws its water from the Amistad Reservoir
located along the Rio Grande. The current capacity as of
September 8, 2022 is 39.8%.


For other public water systems (PWS) which may have water use
limits for the locals:
www.tceq.texas.gov/drinkingwater/trot/droughtw.html


Locations that do not currently have mandatory restrictions
continue to strongly promote year-round water conservation.

SOIL MOISTURE IMPACTS.

As of September 1, the Climate Prediction Center (CPC) analyzes
the percent of available soil moisture as near to slightly below
normal across South Texas. The available soil moisture ranges from
20 to 30% across the northern Coastal Plains and the Victoria
Crossroads while the Coastal Bend, southern Coastal Bend, and the
Brush Country hover around 50%.

AGRICULTURAL IMPACTS


Texas Crop and Weather Report from Texas A&M AgriLife as of:
September 7, 2022


Coastal Bend Region
- Scattered rainfall improved rangeland and pasture conditions
  slightly
- Soggy fields halted most fieldwork, except for the rice harvest
- Cotton harvest was mostly complete
- Producers anticipated a good hay cutting when conditions dry
  out
- Fresh growth was at a high risk of fall armyworm damage
- Some hay producers had already sprayed for armyworms at
  treatment threshold
- Livestock were in good conditions with prices steady to higher

South Region
- Soil moisture levels were short to adequate
- Many areas received rainfall over recent weeks with average
  amounts ranging from 1-2 inches and some isolated areas
  receiving up to 10 inches
- Cotton harvest was underway in some areas and complete in
  others, while some fields around the district ranged from
  flowering to the boll-opening stage
- Cotton stalk clearing was underway in some fields
- Pastures and rangeland were greening up and forage conditions
  were improving in some areas
- There were reports of mealy bugs and armyworms in pastures
- Bermuda grass pastures looked good with some fields ready for
  cutting and baling but too wet for harvesting
- Hay producers were replanting hay grazer
- Livestock conditions were improving, and cattle prices were
  consistent as sale volume decreased
- Ranchers were still providing supplemental feed to livestock
  and deer
- Producers were preparing fields for cool-season small-grain
  planting


FIRE DANGER HAZARDS.

Fire Danger Map – September 7, 2022
According to the latest Observed Fire Danger Map from the Texas
Interagency Coordination Center (TICC), LOW fire ranger conditions
are currently in place across all of South Texas.

Keetch-Bryam Drought Index (KBDI)
KBDI is an index used to determine forest fire potential, which
is based on a daily water balance considering precipitation and
soil moisture. The KBDI can range from 0 to 800, where a value of
0 represents no moisture depletion, and 800 would be
representative of absolutely dry conditions. A KBDI between 600
and 800 is often associated with severe drought and increased
wildfire potential.


The following table lists the KDBI for counties across the region
as of September 8, 2022.

0-200: Aransas, Bee, Calhoun, Duval, Kleberg, La Salle, Live Oak,
McMullen, Nueces, Refugio, San Patricio, Webb
200-300: Goliad, Jim Wells, Victoria
300-400: None
400-500: None
500:600: None
600:700: None
700:800: None

According to the Climate Prediction Center (CPC), La Nina remains
present and is favored to continue through Northern Hemisphere
winter 2022-23, with a 91% chance in September- November,
decreasing to a 54% chance in January-March 2023.


The following table through the month of August shows:
1. Monthly rainfall totals (deficits/surplus) in inches
2. Year-to-date rainfall totals (deficits/surplus) for 2022 in inches
3. Average monthly temperatures (departure from normal) in degrees F

PRECIPITATION/TEMPERATURE OUTLOOK...

Local forecast through the next 7 days (SEP 10 – SEP 17):
Drier conditions are in store for the next several days, although
a rogue shower/thunderstorm or two will remain possible at times.
A weak frontal boundary will move through on September 11 or
September 12, but moisture will be lacking and the most South
Texas could see is a wind shift. Chances for rain do increase by
September 15 as moisture increases over the region.

CPC outlook for days 8-14 (SEP 16 – SEP 22):
Above normal temperatures and near normal rainfall.

CPC outlook for 1 month (SEP):
Chances for above normal temperatures. Equal chances of above,
below, or near normal rainfall.

CPC outlook for 3 months (JUN – SEP):
Chances for above normal temperatures. Equal chances of above,
below, or near normal rainfall.

Monthly Drought Outlook (SEP):
Drought remains but improvements are expected, with likely
removal.

Seasonal Drought Outlook (SEP 1 – NOV 30):
Drought remains but improvements are expected, with likely
removal.


HYDROLOGIC SUMMARY AND OUTLOOK...

USGS Streamflow Map – September 10, 2022.

Heavy rains has led to great improvements in local creeks and
rivers. Most of the creeks and rivers are running from normal to
much above normal. The only sites at below normal flow are the San
Fernando Creek at Alice, and the Guadalupe River at Victoria.


The following table shows the current reservoir levels as of:
September 1, 2022

Reservoir            Normal Pool    Current Pool    % of Capacity
Choke Canyon          220.5 FT      198.0 FT          34.4%
