Groundwater Maps

The links to the maps below provide landowners and water users a unique “inside” look into the District’s groundwater and aquifer patters.

In aquifers, groundwater behaves much like surface water in its patterns of flow. For instance, the water table surface, in porous ground such as sand and gravel, generally follows the topography of the land. Similar to surface water flowing from the top of a hill down into a stream valley, groundwater flows from the groundwater divide to the lower groundwater elevations. The difference between the flow of water from high to low in the underground is that it is measured in terms of years. 

The data is compiled from measurements of more than 200 wells throughout the District taken in the Fall of 2012. The measurements are then converted into the contour maps which are provided as links below.

Depth to Water In Wells - This map indicates the depth to groundwater in the various wells throughout the District. It provides a good estimate of pumping depths and associated costs.

Water Surface Elevation - This maps provides the level of the water surface in the wells as it compares to elevation above sea level. This map provides a more accurate depiction of how the groundwater will move throughout the District as the higher water will seek a natural level, flowing into the lower basin areas.

Water Surface Elevation 3D - This map takes the water surface elevation and converts it into a three-dimensional look, depicting the District’s groundwater in a topographical manner and showing how the higher levels (dark blue) will flow down into the valleys (brown).

The District updates this information annually and uses the data for long-term planning. If you have any questions, or would like copies of the data, please contact the office.
