Information about the Management team at the Harris-Galveston Subsidence District. Datasets of water-level changes and altitudes in the Chicot, Evangeline, and Jasper aquifers. #Hiring adopted as an effective alternative to manual contour interpolation. The reduction in pumpage has resulted in the increase of water- level in the aquifer system in those areas and a reduction in subsidence rates. Land subsidence is sinking of the land surface, caused by compressing the many layers of clay beneath the surface. Harris County MUD 501 is within the boundaries of the Harris Galveston Subsidence District (the Subsidence District) which regulates groundwater withdrawal. Land subsidence occurs when large amounts of groundwater have been excessively withdrawn from an aquifer. This report documents the impact of groundwater use on aquifer water levels and subsidence within the District and was prepared in accordance with an Inter-local Agreement between the District and the Harris-Galveston Subsidence District (HGSD). For detailed information on the processing methodology, please refer to https://ascelibrary.org/doi/10.1061/%28ASCE%29SU.1943-5428.0000399. When we pump large amounts of water from the aquifers beneath us, we pull water out of the many layers of clay, which causes the clay to compact, lowering the elevation of the land above.

This effort has published aquifer levels and subsidence data since 1975 and is a great example of what can be accomplished through sustained collaboration between, city, county, regional, and federal partners.

PDF Water-Level Altitudes 2016 and Water-Level Changes in the Chicot - USGS These efforts have identified and documented the susceptibility of land surface subsidence due to the production of groundwater in the Chicot and Evangeline aquifers. The District provides for the regulation of groundwater withdrawal throughout Harris and Galveston counties for the purpose of preventing land subsidence, which leads to increased flooding.

The public hearing fulfills the requirements of the Districts enabling legislation, which states that the Board of Directors shall hold a public hearing to take testimony concerning the effects of groundwater withdrawals on the subsidence of land within the District during the preceding year. While some areas in Houston have significantly reduced their groundwater pumping (particularly with the creation of subsidence and groundwater districts, whose purpose is to regulate groundwater pumping), subsidence still remains a threat for the region. Alters the flow of creeks and bayous which may increase the frequency and severity of flooding.

From USGS well monitoring over decades they are able to show that once subsidence districts are created, groundwater levels rise significantly, thereby decreasing subsidence issues in their districts. The RGUP originally started in 2010 as the Harris-Galveston Subsidence District (HGSD) 1999 Regulatory Plan Update, but due to its benefits to other regional groundwater regulatory agencies, the Fort Bend Subsidence District (FBSD) and the Lone Star Groundwater Conservation District (LSGCD) joined the collaborative effort in 2010.The primary benefit of collaboration between these three entities is that each of them could use the RGUP to vet their existing regulatory plans using updated population/water demand data and groundwater modeling capability, and in the case of HGSD and FBSD, investigate the physical effects of changing their existing regulatory plans to accommodate the practical realities facing their stakeholders while successfully completing the Districts mission objectives.

Last week, some of our Board of Directors and District Staff visited areas that have historically been affected by subsidence and toured important projects that have been implemented to prevent further subsidence in the Houston area.

The RGUP was jointly supported by the Harris-Galveston Subsidence District, the Fort Bend Subsidence District, and the Lone Star Groundwater Conservation District. On the first stop, we visited the Texas City Rainwater Pump Station, where Texas Citys Emergency Management team takes runoff rainwater from ditches in the area and pumps it into Moses Lake. The RGUP was jointly supported by the Harris-Galveston Subsidence District, the Fort Bend Subsidence District, and the Lone Star Groundwater Conservation District. While some of the duties and goals are similar to those of groundwater conservation districts, Harris-Galveston Subsidence District (HGSD) is not governed by Chapter 36 of the Texas Water Code. Created by the Texas Legislature in 1975 to stop further subsidence in the Houston-Galveston region. The Authority has developed a groundwater reduction plan (GRP) and obtained Subsidence District approval of its GRP. Search form lists all water wells with a HGSD permit in a given area.
