Accurately Estimating Evapotranspiration: The Third Colorado ET Workshop
Learn about new technologies to determine evapotranspiration (ET) and the advantages and disadvantages compared to current methods at the Third Colorado ET Workshop. The workshop will present ET estimation methods and the information required to use them, including weather and satellite data. Presenters will also describe the latest research in ET estimation for both well-irrigated and deficit-irrigated crops. They will discuss how these methods could be used for more accurate and standardized consumptive use calculations for both permanent water transfers and alternative temporary transfers.

South Platte High Groundwater Analysis in the Gilcrest-LaSalle and Sterling Areas -- Final Report
There have been increased occurrences of high groundwater issues since about 2008 in several areas in the lower South Platte Basin, primarily in the Gilcrest-LaSalle area and in two subdivisions on the west side of Sterling. In collaboration with CWCB, the Colorado Division of Water Resources (DWR) initiated detailed data collection and monitoring of the hydrologic conditions and drivers in the Sterling and Gilcrest-LaSalle areas in spring 2012 with the intent of hiring a third-party consultant to analyze the data, quantify the drivers of water table change, and identify relationships among the drivers. The overall goal of the project described in this report was to create a water budget that can help describe the hydrologic and hydrogeologic influences that may be causing high groundwater in the Sterling and Gilcrest/LaSalle areas.

House Bill 15-1013 authorizes the CWCB, in consultation with the State Engineer, to select and administer two pilot projects for the purpose of providing the CWCB and State Engineer with sufficient data to evaluate two alternative methods of lowering the water table in the Gilcrest and Sterling areas along the South Platte River that are experiencing damaging high groundwater levels.
