That data is included in the National Aquatic Resource Surveys, a national overview of water quality. The IDEM Watersheds programs - Nonpoint Source and Total Maximum Daily Load (TMDL), contribute data and information about pollutant loads that staff and watershed groups use when collaborating on planning and implementation activities that will improve water quality.当前可用数据如下： 活跃站点（Active Sites）：https://gisdata.in.gov/portal/home/item.html?id=854bd57c7d5a4938bc3b78abf6cd97e7 非活跃站点（Inactive Sites）：https://gisdata.in.gov/portal/home/item.html?id=a5d9d66bff7d400bb5c13da3f0d2ccab 印第安纳州的部分地表水每年会接受采样工作，采样由印第安纳州环境管理部（IDEM）开展，或在美国环境保护署（U.S. EPA）的支持下完成。此类数据已纳入《国家水生资源调查（National Aquatic Resource Surveys）》这一全国性水质概览项目。 印第安纳州环境管理部的流域项目——涵盖非点源污染（Nonpoint Source）与最大日负荷总量（Total Maximum Daily Load, TMDL）项目——会提供与污染物负荷相关的数据及信息，供工作人员与流域团队在协作开展水质改善相关的规划与实施活动时使用。
