...Update for Drought Conditions...

Synopsis...
Drought conditions continue to persist across much of southeast
Texas with degradation continuing along the coast. With that
said, there has been some slight improvements in a few of our
northern counties thanks to recent rainfall. A detailed analysis
of the drought conditions and impacts is provided below.

Summary of Impacts...
Some rice farmers in SE TX have had to flush fields to germinate
seeds in areas that missed recent rainfall. These areas include
parts of Brazoria, Brazos, Burleson, Chambers, Fort Bend,
Galveston, Grimes, Harris, Liberty, Madison, Montgomery, San
Jacinto, Walker and Waller counties. Some farmers in Austin,
Colorado, Jackson, Matagorda, Washington and Wharton counties
continue to wait for rain before planting due to low soil
moisture. Had there been enough soil moisture all cotton planting
would have been finished by now. Previously noted impacts... On
March 3, 2020, Governor Abbott updated the counties within the
disaster declaration for drought. The counties include Burleson,
Colorado, Jackson, Wharton counties. Fire danger is becoming a
greater worry; however, these counties have not yet implemented
burn bans. Soil moisture remains low for planting in Texas`
Coastal Bend and growers have been opting to delay planting in
Austin, Colorado, Jackson, Matagorda, Washington, and Wharton
counties. Supplemental feeding for livestock continues. In Austin,
Colorado, Jackson, Matagorda, Washington and Wharton counties,
livestock producers continue to feed supplemental protein and hay,
although hay supplies have been tighter than normal. Recent
rainfall has stimulated pasture growth in parts of these areas,
but the lack of soaking rains has delayed early spring planting as
well as fertilizer application for additional growth of winter
forage crops. Impacts will continue to be updated as additional
information becomes available.

Fire Impacts...
As of April 2nd, no counties are under Burn Bans.

The Keetch-Byram Drought Index...
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 KBDI for counties across the region
as of April 1st that are experiencing drought conditions.
KBDI 0-200... Houston, Trinity, Madison, Walker
KBDI 200-300... Polk, San Jacinto, Montgomery, Grimes, Waller,
Brazos, Washington
KBDI 300-400... Galveston, Chambers, Austin, Liberty, Harris,
Burleson
KBDI 400-500...Wharton, Fort Bend, Matagorda, Brazoria, Colorado
KBDI 500-600... Jackson

Climate Summary...
The month of April is starting with near normal temperatures and
near normal rainfall across the region. Average temperatures near
College Station are running about 1 degree below normal and the
average rainfall is roughly 0.09 inches below normal. Below is a
list of the counties with their highest classification as
designated by the U.S. Drought Monitor as of April 2rd.

None Houston, Trinity
D-0... Polk, San Jacinto, Walker, Madison, Montgomery
D-1... Chambers, Liberty, Grimes, Washington, Brazos, Burleson
D-2... Galveston, Brazoria, Harris, Matagorda, Fort Bend, Waller
D-3... Jackson, Colorado, Wharton, Austin

A brief description of the U.S. Drought Monitor classifications currently
ongoing in southeast Texas can be found below:
D3...Extreme Drought - Soil has large cracks and soil moisture is
very low.
D2...Severe Drought - Crop or pasture losses likely.
Some water shortages common and some water restrictions imposed.
D1...Moderate Drought - Some damage to crops and pastures.
Reservoirs or wells low. Voluntary water restrictions imposed.
D0...Abnormally Dry - Short term dryness. Plant growth slows.
Minor water deficits.

Precipitation/Temperature Outlook...
The local forecast over the next week...An active pattern is
expected through the middle of next week. There is the potential
for heavy rainfall starting tomorrow going into Saturday, with
rain chances continuing Sunday as the cold front lingers over the
area as a few weak disturbances come and go. Models suggest a wet
pattern continuing Monday through Wednesday, but it will depend on
where the upper ridge sets up over the area. For the month of
April, the Climate Prediction Center (CPC) is calling for a 56%
chance of above normal temperatures, 33% chance for near normal
temperatures, and 11% chance for below normal temperatures. CPC is
also forecasting 53% chance of above normal precipitation, 33%
chance of near normal precipitation, and 14% chance of below
normal precipitation amounts for the month of April across most of
southeast Texas. The three-month outlook (for April through June)
from CPC shows southeast Texas with a 58% chance of above normal
temperatures, 33% chance for near normal temperatures, and 9%
chance for below normal temperatures. With regards to rainfall,
the three-month outlook from CPC shows southeast Texas with an
equal chance of above, below, and near normal rainfall amounts.

Hydrologic Summary...
Southeast Texas streamflows as of April 2nd... Streamflows across southeast Texas are near normal to much above normal along the Trinity and Brazos River basins, near normal to below normal along the San Jacinto, San Bernard and Colorado River basins, and much below normal on the Lavaca and Navidad River basins.
Lake Name                 Date       Level Percent Full (%)
Houston County Lake      4/2               100.0
Lake Livingston           4/2               100.0
Lake Conroe 4/2  97.1
Lake Houston 4/2  94.5
Lake Somerville 4/2100.0
Lake Texana       4/2  68.9

provided at an earlier date.
