Hydrogeologic Investigations of the Trinity Aquifers in Western Travis County along a Portion of Lake Travis and a Transect from Northern Hays County to Bell County, Central Texas

The Barton Springs/Edwards Aquifer Conservation District (BSEACD), in cooperation with Travis County, compiled existing and new hydrogeologic data to evaluate groundwater resources in central Texas. Analysis and interpretation of these data provide the foundation for hydrogeologic evaluations presented in the Hydrogeologic Atlas of Southwest Travis County, Central Texas (Hunt et al., 2020). The Atlas describes the hydrogeologic framework, aquifer conditions, and conceptual model of the Middle and Lower Trinity Aquifers in Hays and southwestern Travis County (SWTC). This report presents the continuation of the hydrogeologic studies in cooperation with Travis County. The studies described in this report help characterize two important hydrogeologic aspects identified in the Atlas of Hunt et al. (2020) that warranted additional investigation. This was accomplished through two focused studies: Study 1: Hydrogeologic Investigations of the Trinity Aquifers in Western Travis County Along a Portion of Lake Travis; Study 2: Hydrogeologic Investigations of the Trinity Aquifers along a Transect from Northern Hays County to Northern Bell County, Central Texas

巴顿斯普林斯/爱德华兹含水层保护区（Barton Springs/Edwards Aquifer Conservation District, BSEACD）与特拉维斯县（Travis County）合作，整合现有及新增水文地质数据，以评估德克萨斯州中部的地下水资源。对上述数据的分析与解读，为《德克萨斯州中部特拉维斯县西南部水文地质图集》（Hunt等，2020）中呈现的水文地质评价工作提供了核心依据。该图集阐述了海斯县及特拉维斯县西南部中、下三一含水层（Trinity Aquifers）的水文地质框架、含水层赋存状态与概念模型。本报告延续了与特拉维斯县合作开展的水文地质研究工作，所载研究旨在厘清亨特等（2020）所编图集明确识别出的、亟需开展补充调研的两项关键水文地质议题。此项研究通过两项针对性专题研究完成：专题研究1：特拉维斯湖沿岸特拉维斯县西部三一含水层水文地质调查；专题研究2：德克萨斯州中部海斯县北部至贝尔县北部断面沿线三一含水层水文地质调查
