General Information

Instructions for Use

If you know the Obwell number or the MDH Unique number for a well select the appropriate dropdown box and chose the well you are interested in. Another window will open which will show the hydrograph, the well construction details, and the specific water level readings for that obwell. (See below for methods to copy, print and save this information.)

If you know the general area for which you are seeking information, but do not know the Obwell number or Unique number, use the map to zoom into the area of interest.

On the map, the symbols represent the well locations. As you zoom into an area, the number of wells may increase or decrease depending on the wells in the area of interest. When you click on a well symbol another window will open and you will get a summary of the information about that well and a link that will provide you with a hydrograph of water levels from that well, well construction details, and the actual water level measurements. (See below for methods to copy, print and save this information.)

You can zoom into an area using the zoom bar on the left side of the map or you can click the Drag Zoom box, which will allow you to outline an area and zoom in on it.

If the wells are close together (less than 5 feet apart), you may not be able to zoom in far enough to see the separate wells. To get the information for the wells you can use one of the dropdown boxes or you can contact the Groundwater Monitoring Coordinator ( and get the information.

To save the data or the obwell descriptive text:

Water level readings saved in the above manner as text files can be easily opened and formatted with most spreadsheet programs. This allows custom creation of hydrographs.
