The observation well network consists of 1,556 state-owned wells used to measure ground water levels throughout South Dakota. The data provides geologic and hydrologic information which is used to evaluate the effects of climatic conditions, effects of water use from the state's aquifers, and availability of water for ground water users. Information regarding the well construction and subsurface formations encountered during the well construction is also available. If you have any questions about interpreting the data, please call the Water Rights Program at 605.773.3352.
The "Observation Wells" layer identifies wells observed by South Dakota Department of Environment and Natural Resources (DANR).
This layer contains each well's name, aquifer it is located in, total depth, total casing, USGS ID (If also observed by USGS), the legal description, and the latitude and longitude of the well, and the current run it is on.
There are several search options. You can search by one or any combination of the following: observation well name, county, PLSS legal description, and aquifer.
Other options include "And" and "Or"
The Streets or sometimes 'Imagery with Labels' button changes the basemap for the map.
A basemap is the background map that provides reference information for the other layers. It allows you to easily identify where points are located. You may want to change the basemap. For example, you may prefer to use a street map vs. an imagery map so you can easily find your house.
Clicking on this button will switch between a street and imagery basemap.
