WLCI: Groundwater Streamgages in the upper Green River Basin

Science Center Objects

Real-time groundwater streamgages are created at existing streamgages by adding streambank wells (piezometers) to expand the understanding of groundwater/surface-water interaction. The object of this project is to:

  • Identify interactions between the stream and near-surface groundwater
  • Evaluate data to determine annual patterns and changes over time

In order to create a groundwater streamgage, it is necessary to collect four real-time parameters: stream and groundwater elevation, and stream and groundwater temperature. (A generalized schematic is the design is shown at right.) These parameters on their own define the gradients between the two resources, but when using the heat as a tracer method of analysis, data can be modeled to quantify the movement of water between the stream and groundwater.

Groundwater streamgages were established at two sites in the upper Green River Basin: the New Fork River near Big Piney and the Green River near LaBarge.

Currently, real-time data are available showing the current conditions of the river and one streambank well at the two sites: 

New Fork River near Big Piney (streamgage 0920500) stream and groundwater elevation, and stream and groundwater temperature.

Green River near LaBarge (streamgage 09209400) stream and groundwater elevation, and stream and groundwater temperature.
