playa lake recharge

Topographic surveys and satellite data were used to develop flood histories for 72 playas. Recharge occurs both through playa basins and along the perimeter (or annual rings) of playas. Artificial Recharge in the Southern Ogallala—Experiences with Playa Lake Water and Filter Underdrains. Who We Are; Contact; Media Contact; Job Opportunities; Annual Reports and Information; Bureau Directions and Maps; Area Hotels; Sign up for Bureau Announcements The Playa Lake Tour and Workshop is free for landowners and land managers with playa on their land and includes lunch both days and tour transportation. The Texas Playa Conservation Initiative (TxPCI) was founded in January 2015 to address playa resource concerns for the benefit of the Ogallala Aquifer, wildlife, and residents and producers in Texas’ playa region. Playas on the Great Plains On the western Great Plains of the United States, the term "playa" is used to describe the tens of thousands of small, shallow intermittent lakes that form in topographic deprressions. If covered with salt, it is known as a salt flat. The amount and rate of recharge is not precisely known, and the impact of the land use surrounding each playa lake on the amount of runoff has not been quantified. A majority of playa landowners (74%) were willing (28% ‘highly’ and 46% ‘moderately’) to plant native grass buffers around playas if given an incentive. Diagram showing construction of recharge well, observation wells, and test holes, Dunlap site 17 15. Five years of Phase 1 monitoring has been completed. On our farm, we have probably the largest playa lake in the county, and it’s 125 acres. The mission of Playa Lakes Joint Venture (PLJV) is to conserve the playas, prairies and landscapes of the western Great Plains — including portions of Colorado, Kansas, Nebraska, New Mexico, Oklahoma and Texas — through partnerships for the benefit of birds, other wildlife, and people. Environmental Protection Agency.] Playa-lake basins on the Southern High Plains of Texas and New Mexico: Part II. Click to enlarge. Although landowners are concerned about the future of the Ogallala Aquifer, not all understand playas’ crucial role in groundwater recharge. Research shows that water reaching the aquifer through playas is of higher quality than that going through other pathways. Playa lake recharge rates are approximately 3 cm/year, ten times the High Plains average. https://lubbockagain.blogspot.com/2014/11/the-playa-lakes-of-south-plains.html groundwater recharge and attempt to quantify recharge rates. The 200,000 acre feet of water collected annually by Texas playas represents less than four percent of the 5.6 million acre-feet of 2010 irrigation demand for Regions A and O. Hemphill County Underground Water Conservation District, Mesa Underground Water Conservation District. The projects are typically 24 month projects that are considered complete after a … Once the subject of much debate, mounting evidence points to playa lakes as a critical recharge source for the Ogallala aquifer. Playa Lake Recharge - EPA Wetland Grant FY2014-17 Final Report. Research has shown that these shallow, temporary wetlands are a primary source of recharge for the Ogallala Aquifer, contributing up to 95 percent of the water flowing to the aquifer and also improving the quality of that water. The amount and rate of recharge is not precisely known, and the impact of the land use surrounding each playa lake on the amount of runoff has not been quantified. Registration is required. Playa lake restoration and enhancement is a key area of focus in Texas as playa lakes are a key resource for wildlife, people, and the recharge of the Ogallala aquifer. These cracks eventually swell shut as the clay absorbs water making the basin impermeable. AQUIFER RECHARGE UTILIZING PLAYA LAKE WATER AND FILTER UNDERDRAINS PHASE IV by Lloyd V.Urban B. J. Claborn R. H. Ramsey January 1988 Texas Tech University WATER RESOURCES CENTER Lubbock, Texas . Historically playa lakes have been farmed through, grazed out, or modified for various agriculture production purposes. The following photos show the 2010 playa after the rains. For others who would like to attend, there is a $50 fee which also covers lunch. Long-term trends of increasing evaporation and observed declines in playa water volume between 1996 and 2014 suggest that less water may be available from playas in the future. Potential pollution of the Ogallala by recharging Playa Lake water--pesticides. Recharge is often discussed as dominant within one of the following basin locations: mountain block, diffuse, moun- tain front, stream channel, and playa lake. The remaining 15% are part of natural grasslands, with the average size of a playa being 3.7 acres. It is true that a hotter climate pumps more moisture into the atmosphere, and does bring more rain. Large, infrequent flood events produce most of the recharge. The Texas Playa Conservation Initiative (TxPCI) was founded in January 2015 to address playa resource concerns for the benefit of the Ogallala Aquifer, wildlife, and residents and producers in Texas’ playa region. Pleistocene climatic record and a playa lake genesis model of Bowler and Teller (1986) as a guide, it was estimated that the playa lake would have achieved a maximum discharge of approximately 700 m. 3 /yr (0.03 mm/yr of recharge). Once filled, rainwater and runoff can reach the large cracks in a dry playa—which is essential for recharge to occur—rather than collecting in the pit. Intensive field monitoring will be discontinued at most sites in early 2016. PARTNERSHIP INFORMATION: The Playa Lakes Joint Venture (PLJV) supports this project because it has the potential to catalyze Playa conservation work in Kansas by providing a better understand of the recharge contribution of the Playas as well as the economic considerations for Playas in production.

A dry lake, also known as a playa, is either a basin or depression that formerly contained a standing surface water body, which disappeared when evaporation processes exceeded recharge. These desert playas are formed in basins with internal drainage and the term playa is roughly synonymous with a dry lake bed or, in some cases, an alkali flat. Rapid infiltration from small floods on dry, cracked soil is typically held in the top 10 feet of the soil and can be transpired by plants during dry spells between floods. Enhanced playa recharge may provide a sustainable local water resource but won't substantially change the overall water budget for the Ogallala. Water level monitoring will continue at all sites pending Phase 2 approval. If covered with salt, it is known as a salt flat. In fact, water reaching the aquifer today started its journey during our parents and grandparents lifetimes; and the water recharging now will be available for today’s children and future generations. A healthy playa lake with native grass buffer can offer many benefits, including groundwater filtering, recharge, and is a lifeline for biodiversity. This study, based on analysis of excavations and 63 hollow-stem auger cores taken from 10 lake basins in the study area around the Pantex Plant northeast of Amarillo, Texas, resolves longstanding controversies regarding origin, evolution, and recharge behavior of playa lakes. Playa Lake Restoration & Enhancement. Mountain block recharge occurs directly into the underlying bedrock with- out runoff and is widely distributed in areas of higher moun- tainous terrain particularly where there is permeable Recharge is often discussed as dominant within one of the following basin locations: mountain block, diffuse, moun- tain front, stream channel, and playa lake. These studies have also focused on understanding detailed hydrologic characteristics of playa lakes and the role of sedimentation in changing the natural hydro-periodicity of playa lakes. Healthy Playas Improve Groundwater Quality. This happens in two ways: first, as rainfall and runoff travel toward the playa, the surrounding grasses trap sediments, which can carry contaminants into the playa; then, as the water moves through the clay floor of the playa, a second ‘cleaning’ process occurs as the soils beneath the playa remove nitrates and other dissolved contaminants. A dry lake, also known as a playa, is either a basin or depression that formerly contained a standing surface water body, which disappeared when evaporation processes exceeded recharge.If the floor of a dry lake is covered by deposits of alkaline compounds, it is known as an alkali flat. She believes that, "the future of playa lake research does not lie in the investigation of individual playas and that recharge values that are representative of a "type area" will come from comprehensive studies of the Ogallala aquifer that will combine all of the critical data that affects recharge on … Playa Lakes Joint Venture held a Playa Recharge Summit with scientists and researchers who study various aspects of playas to determine what is known about groundwater recharge through playas. Monitoring equipment was installed in 38 playas in 13 counties across the Panhandle. As communities struggle to deal with drought and declining aquifers, playas—a major yet relatively unknown natural resource—are playing a role in replenishing and improving the quality of the region’s water supply. 3) that are likely areas of recharge (Wood and Osterkamp, 1987). The picture was taken in 2007.. Plains, however, it is the floors of playa-lake basins (fig. In our eight years of living here we have had the playa fill with surface water four times. Fifteen percent of the playas receive an average of more than a foot of water per year. AQUIFER RECHARGE UTILIZING PLAYA LAKE … Click on a photo below to read what they had to say. They are an important source of groundwater recharge for the Ogallala aquifer. Recharge rates in playa basins are 10 to 1,000 times higher than under other areas, and groundwater recharge may exceed three inches per year in unaltered playas. In the Southern High Plains of Texas, it is accepted that focused recharge to the High Plains Aquifer (locally known as the Ogallala) occurs through over 20,000 playa lakes, which are local depressions that collect storm runoff. About. Contact your local Natural Resources Conservation Service Center for more information. In fact, there are more than 19,000 shallow, ephemeral lakes that dot the Texas High Plains, making the region home to the highest density of playa lakes in North America. Attempts to recharge playa water in the past have failed due to the clogging of pits or wells by the fine playa bottom material suspended in the water. Click on a photo below to read what they had to say. ... Playa basins expand laterally as recharge is concentrated at the edge of the playa floor Playa lakes are a critical source of water in a region that receives less than 20 inches of rainfall on average every year. Sedimentation in playas is the result of soil erosion from adjacent tilled croplands (TPWD, 2003). “A fast turnaround in western Kansas would be three years. Abe Lollar 620-214-2693 Click on a photo below to read what they had to say. She believes that, "the future of playa lake research does not lie in the investigation of individual playas and that recharge values that are representative of a "type area" will come from comprehensive studies of the Ogallala aquifer that will combine all of the critical data that affects recharge on … If the floor of a dry lake is covered by deposits of alkaline compounds, it is known as an alkali flat. Healthy, functioning playas are areas of focused recharge and improve the quality of water flowing into the Ogallala Aquifer. Playa Lakes Joint Venture held a Playa Recharge Summit with scientists and researchers who study various aspects of playas to determine what is known about groundwater recharge through playas. Wood and others (1997) have shown that 95 per­ cent of the total ground-water recharge to the Southern High Plains aquifer occurs in the 5 percent of the area oc­ cupied by playa … 1, Panhandle Groundwater Conservation District, North Plains Groundwater Conservation District, Sandy Land Underground Water Conservation District, Llano Estacado Underground Water District, Texas Natural Resources Information System (TNRIS), Texas Water Infrastructure Coordination Committee (TWICC), Overall Goal: Increase recharge to the Ogallala Aquifer from the 20,000 Texas playa lakes, Phase 1—Initial three years of monitoring completed: Quantify volume of water in playas and measure current recharge rates from selected playas, Phase 2—Pending $1 million additional funding: Playa modifications to assess potential for increasing recharge to the Ogallala Aquifer.
