On the Cusp of Drought Heading into Summer 2018

No Drought (Preparing for it, so please conserve!)
Lovelady well height: 487. ft-msl (166.4 ft-Depth to Water)
Barton Springs: approximately 56 cfs 10-day average

The BSEACD drought outlook valid from May 10, 2018, to May 24, 2018 remains in “NO DROUGHT” as aquifer levels at the Lovelady well were helped out with a 3 inch rain event in early May that stabilized water levels to stay above Alarm Stage level and Barton Springs flow was also helped by the rains that boosted flow up to 66 cubic feet per second

Lovelady water levels are stable just after an early May shower of 3”. All area creeks saw a rise in stage and Onion creek went from dry to 4’ feet of stage in Buda with flow peaking at 28 cfs. Antioch cave valves were open and taking plenty of needed recharge. Onion creek has returned to dry as we have received only 1 inch since early May.

Barton Springs flow has also been on the rise since the rain, raising flow to a peak 66 cfs (up from 57 cfs just days before). The recent rain has postponed the BSEACD prediction of falling below Alarm Stage (below 38 cfs) from mid April to late June if we are not to get additional rain. This prediction seems to be staying on cource with such little rain.

A declaration of drought for the aquifers will be made by the District based on which of the two drought indicators enters drought condition first. Because of the 7 “ rain so far this spring, aquifer levels and Barton Springs flow have increased. This holds off drought for a bit longer and postpones the BSEACD prediction of  drought conditions between April and June of this year to late June to early July. With The development of La Nina conditions, which is a tendency for hotter and drier conditions, may exacerbate the advance of drought.

Desalination and ASR Feasibility Assessment

No Drought
Lovelady well height: 487.6 ft-msl (165.7 ft-Depth to Water)
Barton Springs: approximately 62 cfs 10-day average

The Edwards Aquifer has been considered a vast source of inexpensive, high-quality drinking water for many years. However, restrictions have been placed on production from the Edwards in recent years, and rising demands have increased faster than the provision of other additional sources. With the past significant reliance on the Edwards Aquifer, other potential sources warrant further consideration. Potential sources within the boundaries of the BSEACD that are being minimally used, if at all, include the Middle and Lower Trinity aquifers, and the brackish portion of the Edwards. One prospective new water supply source is the large quantity of brackish groundwater in the eastern portion of the District. Texas Disposal Systems is located on this “donut hole” which is outside the jurisdiction of the BSEACD. Multi-port wells installed here have provided data necessary to analyze the feasibility of desalination of the brackish
groundwater; management of desalination treatment residuals; and using the treated water for aquifer storage and recovery (ASR).

This year's Well Water Checkup will be on Wednesday, April 25, 2018 from 9am till 2pm.  Screening is available to the first 50 well owners in the District to come in, pre-register and pick up sampling supplies and instructions.  Sample supplies must be picked up by Tuesday, April 24.  Come in to get supplies at the District office, 1124 Regal Row, Austin, TX 78748.



The USEPA recommends that private water wells should be tested annually for contaminants that can jeopardize the health of its users, especially vulnerable populations like children, the elderly, or those with compromised immune systems.  Samples from private water wells will be screened for common contaminants, including fecal coliform bacteria, nitrates, and salinity.

You'll be able to bring in your water sample for analysis on April 25 between 9am-2pm.  Samples need to be less than 24 hours old for best results.  District staff will screen for salinity and nitrates while you wait.  Bacteria samples will be processed by an off-site lab.  Results will be mailed the following week.  There will be an after-hours drop-off available starting at 5:00pm on Tuesday, April 24.

2017 Aquifer Status in Review

No Drought
Lovelady well height: 501.8 ft-msl (151.5 ft-Depth to Water)
Barton Springs: approximately 61 cfs 10-day average

2017 began in a status of No Drought following a trend which began back in 2014. In September ‘14, water levels began to rise after above-average rainfall. Steady recharge throughout 2015 and ‘16 continued to increase aquifer water levels as well as Barton Springs flow. In January 2015, the Board updated the drought status from Stage II Alarm Drought to No Drought. While measurements began to decline in October 2016, and have steadily continued down, they remain above drought warning levels. As of December 2017, we maintain a status of No Drought.

Austin has received 39" of rain which is just above our average rainfall (32" - 36") in 2017, which has produced little recharge and resulted in aquifer water level decline. While levels are going down, the benefits of previous wet years have provided a bolster against this drop at the Lovelady Monitor Well, which has recorded data since 1949.

The rejuvenating effects of above-average rainfall in 2015 and ‘16 (59” & 55” respectively) well-prepared the region for a somewhat dryer 2017. La Niña conditions (see previous blog entry) in the Pacific are likely to result in continued dry weather through the winter and beginning of 2018.

Happy New Year from BSEACD!!!

La Nina Climate Impacts and Outlook for Texas in 2018

In addition to November’s blog post on  weak La Nina conditions developing in the tropical Pacific, below are some climate forecasts from the Climate Assessment for the Southwest (CLIMAS) team on La Nina’s potential impacts on Central and South Texas. As of early-November, the tropical Pacific and atmosphere were exhibiting weak La Nina conditions. Forecasts favor above-average temperatures and below-average precipitation through approximately February-April 2018.


Drought
Abnormally dry conditions developed in areas of Central and western Texas between August and October while moderate drought conditions remained in southern Texas. Drought conditions in these areas are predicted to persist through February, according to the U.S. Seasonal Drought Outlook.



Temperature
The three-month NOAA temperature outlook (December-February)
favors chances for above-average temperatures for all of Texas through February.


Precipitation
The NOAA three-month precipitation outlook predicts chances for below-average
precipitation for all Texas, except for the northernmost point of the
state (December-February). La Niña conditions tend to lead to below-average
precipitation in the Southwest U.S. and northern Mexico.


Fire
According to the National Interagency Fire Center (NIFC), fire risk is normal for
New Mexico and Texas through December (Figure 9).
However, La Niña conditions, projected to continue through the winter, are
predicted to bring dry and warm conditions to the Southern Plains, including
Central Texas, by January, making grasses and brush
more receptive to fire.

Move over El Nino, La Nina may be on the way

No Drought
Lovelady well height: 516.3 ft-msl (137.2 ft-Depth to Water)
Barton Springs: approxamately 75 cfs 10-day average

Forecasts from the National Oceanic and Atmospheric Administration (NOAA) indicate that a La Nina may make an appearance (55-65% chance) this fall and winter.

La Nina is the opposite of El Nino, a cooling of the equatorial east-central Pacific Ocean. If La Nina does develop, the strength of it (weak, moderate or strong) will determine what impacts it may have on the weather this fall and winter. Typically, the southern tier of the U.S. sees drier than average conditions and temperatures that are above average, while much of the Pacific Northwest and Ohio Valley are wetter than normal and see below average temperatures.(Weather Channel).


What does this mean for Central Texas?
As the La Nina effects suggest, "the latest outlooks for this fall and winter call for rainfall to average near to slightly below normal across our area. Along with that, temperatures should be a little bit milder than normal from October all the way through the end of winter." -Bob Rose, LCRA Chief Meteorologist

Hurricane Harvey and Central Texas

Hurricane Harvey and Central Texas

Hurricane Harvey made landfall on the Texas Gulf Coast late Friday, bringing with it one of the most disastrous floods in the state’s history. From Corpus Christi and Rockport to Houston and La Grange, wind and rainfall from the storm caused damage and displacement on a catastrophic scale. Houston alone received over 51” as of August 31st. That’s the greatest amount ever recorded in the Lower 48 states from a single storm.

The effects of Harvey have extended to Central Texas. Specifically, regarding rainfall:
  • Buda saw 11.7” according to LCRA Hydromet
  • Manchaca received 9.6” according to BSEACD gauges
  • Driftwood recorded 7.4” according to LCRA Hydromet
  • Austin (Mabry: 5.9”, ABIA: 6.2”) got roughly 6” (KXAN weather diary)
  • Wimberley took 5.3” according to LCRA Hydromet

While rain was nearly constant in the region beginning Friday evening and continuing into early Monday, the effects on the stage level of local creeks and rivers might seem unexpectedly subtle. Although all saw a rise in stage and flow, none achieved flood status as a result of the downpour.

Springflow at Barton Springs
saw a slight increase of five cubic feet per second (cfs) while Jacob’s Well Spring measured a 40 cfs increase.
 

Water levels in the Barton Springs Edwards Aquifer Conservation District
(BSEACD) Lovelady monitor well were declining until the rain event brought stabilization. 

Onion Creek at Driftwood saw a quick climb to around 210 cfs late Sunday (8/27) night, though the peak was short-lived and never reached flood stage status.


The LCRA reports rainfall totals near the Highland Lakes ranged from less than an inch near Lake Buchanan to widespread totals of 2-4 inches near Lake Travis. This was not enough rain to make a significant difference in lake levels.
As Harvey drifted back toward the gulf late Sunday, rainfall decreased and stage levels began to quickly decline. After the deluge, the area received 9 inches in August, 7 inches above the average for the month.
