The TWDB Groundwater Availability Model for the Southern High Plains estimated total recharge at 1,032,905 acre-feet in 2000; recharge enhancements at the 3000 wettest playas might gain 40,000 to 80,000 acre feet per year. The volume of water collected in playas from 1996 to 2014 averages 200,000 acre-feet per year, significantly less than estimated by previous studies. Contact your local Natural Resources Conservation Service Center for more information. Aquifer recharge occurs through playa basins and along the perimeter of playas. groundwater recharge and attempt to quantify recharge rates. Enhanced playa recharge may provide a sustainable local water resource but won't substantially change the overall water budget for the Ogallala. 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 . 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. It is true that a hotter climate pumps more moisture into the atmosphere, and does bring more rain. If the floor of a dry lake is covered by deposits of alkaline compounds, it is known as an alkali flat. Environmental Protection Agency.] 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 Filling in pits is one of the easiest ways to restore a playa. 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. Fifteen percent of the playas receive an average of more than a foot of water per year. Historically playa lakes have been farmed through, grazed out, or modified for various agriculture production purposes. 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. Artificial Recharge in the Southern Ogallala—Experiences with Playa Lake Water and Filter Underdrains. recharge of playa-lake water, Hufstedler site 15 13. Click on a photo below to read what they had to say. 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. 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 … Properly functioning playas have intact clay basins, are encompassed by grassy buffer strips or prairie, and collect runoff from the surrounding area after large rain events. Playa Lake Field Tour Tuesday January 14, 9 a.m. to 5 p.m.Haskell, Seward and Meade counties. Recharge is often discussed as dominant within one of the following basin locations: mountain block, diffuse, moun- tain front, stream channel, and playa lake. Playas also provide the main recharge to the Ogallala Aquifer, and are vital to local ecosystems and economies. Exceptional flooding in 2015 produced more recharge than the previous four years together. 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. 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. Healthy, functioning playas are areas of focused recharge and improve the quality of water flowing into the Ogallala Aquifer. [Dan M Wells; Ellis W Huddleston; Robert G Rekers; United States. Playa lakes are a critical source of water in a region that receives less than 20 inches of rainfall on average every year. Playa Lake Recharge - EPA Wetland Grant FY2014-17 Final Report. https://lubbockagain.blogspot.com/2014/11/the-playa-lakes-of-south-plains.html “There’s a lot of different factors in how long it takes to restore a playa,” Lollar said. Once the subject of much debate, mounting evidence points to playa lakes as a critical recharge source for the Ogallala aquifer. 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. There are more than 22,000 playa lakes in Kansas, with 85% of that playa acreage in cropland. 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. 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. 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. Drawing of recharge system, Dunlap site 18 16. A playa lake is an ephemeral wetland found across the High Plains. Playas are the most numerous wetlands in the region, with more than 80,000 scattered across the western Great Plains. It is true that a hotter climate pumps more moisture into the atmosphere, and does bring more rain. About. In our eight years of living here we have had the playa fill with surface water four times. This recharge through playas is a continuous process. Healthy, functioning playas are areas of focused recharge and improve the quality of water flowing into the Ogallala Aquifer. The importance of playa lakes in the western Great Plains environment has become abundantly clear over the last 25 years. This picture shows our home reflected in our playa. 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. Plains, however, it is the floors of playa-lake basins (fig. AQUIFER RECHARGE UTILIZING PLAYA LAKE … Monitoring the aquifer’s recharge in this area would be similar in approach to other efforts that study groundwater infiltration if it weren’t for all the playa lakes that dot the panhandle. Enhanced playa recharge may provide a sustainable local water resource but won't substantially change the overall water budget for the Ogallala. Registration is required. A Thousand Points of Recharge: Can alternative management strategies increase recharge from the playa lakes of the Southern High Plains to the Ogallala Aquifer? Get this from a library!
