Search for Observation Well Measurements in South Dakota
The observation well network consists of over 1,500 wells which are used to collect water level and water quality data. The data provides geologic and hydrologic information which is used to evaluate the effects of climatic conditions and the effects of water use from the state's aquifers.
You may search using one or any combination of all the following search options or by using the map provided below:
The dots on the map represent observations wells that are actively being measured. To zoom in use the toolbar on the map or double click the map to zoom in and recenter the map. You can also move around on the map using the toolbar or by clicking and dragging with your mouse. The dots on the map can be clicked to view the well name and access a link for details about the well and for measurements.
You may search using one or more of the search options. Leaving search options blank or at their default value will NOT affect the results of your search. However, using more than one search option helps narrow down your search results. For example, searching for section "28" returns records found in all sections numbered 28 throughout South Dakota -- including a township and range number limits section 28 to that specific township/range. If you don't know the township/range, then including the county in your search will help narrow down the results as well.
