Wells

This data set provides information about wells in the State of Missouri. The parent data set is the Wellhead Information Management System (WIMS) database that is maintained by the Missouri Department of Natural Resources (DNR), Missouri Geological Survey (MGS), Geological Survey Program (GSP), Wellhead Protection Section (WHP). The WIMS database resulted from implementation of the Water Well Drillers Law of 1985. The information about well location, well ownership, well completion date, well construction, well yield, static water level, and borehole stratigraphy was provided by well drillers as required by state statute RSMo 256.600-256.640. Wells drilled prior to July of 1987 are not included in this data set.

This data was collected from the Missouri Spatial Data Information Service (MSDIS).

Losing / Gaining Streams

This data set depicts stream segments classified as either losing or gaining by the Missouri Department of Natural Resources (DNR), Missouri Geological Survey (MGS). Classification is dependent on the change in flow rate over a set distance at the time of the site visit. Stream classification is intended to depict sections of streams which are either losing water flow to the subsurface or gaining water flow from the subsurface. Stream classification is required for certain site evaluations under Missouri Code of State Regulation (CSR), 10 CSR 20-8.

This data was collected from the Missouri Spatial Data Information Service (MSDIS).

303d Lakes

This data set contains Missouri’s 2016 Section 303(d) Listed Waters – Rivers and Streams and is a list of certain impaired waters in the State of Missouri. The list is a requirement of the Federal Clean Water Act and is developed biennially by the Missouri Department of Natural Resources. The list contains the names of impaired waters, their unique identification number and identification of specific pollutants and pollutant sources if they are known. This list has been modified by a state-wide public participation process and by review of the United States Environmental Protection Agency (EPA). Waters on the final EPA list must be the subject of a Total Maximum Daily Load (TMDL) study that stipulated the allowable amount of specific pollutants allowed in these waters. All waters are listed for their full size as given in 10 CSR 20-7.031 Water Quality Standards, Tables H.Section 303(d) of the Federal Water Pollution Control Act requires states to list impaired waters for which adequate water pollution control requirements have not been put in place and for which a TMDL study has not been completed.The metadata content associated with this data set was reviewed by Barb Ruppel on 20150127. The metadata content review is intended to ensure that all of the required content is present. The components comprising the metadata document were reviewed by Barb Ruppel on 20150127. The metadata component review is intended to ensure that required metadata components are consistent and understandable to data consumers.en20141201Most current available data was used to reflect waters identified in Missouri’s 2014 Section 303(d) List.

Dams

This data set contains the locations of regulated and non-regulated dams in Missouri. This data is collected and maintained by the Missouri Department of Natural Resources (DNR), Missouri Geological Survey, Water Resources Center (WRC). One of the missions of the Water Resources Center is to ensure that dams in the state are constructed, maintained and operated in a safe manner. This is accomplished by regulation of all non-agricultural, non-federal dams 35 feet or more in height and by providing technical assistance and informational resources to all dam owners.

This data was collected from the Missouri Spatial Data Information Service (MSDIS).

305b Impaired Lakes

The data set contains the names of impaired waters, their unique identification numbers and locations, and identifies specific pollutants and pollutant sources if they are known. This data set is created in conjunction with the Missouri Water Quality Report, which is produced biennially as required by Section 305(b) of the Federal Clean Water Act, and correlates to Tables 14-15 of that report.
