Beginning in 2008, the Basalt Water Conservancy District (District), together with the Colorado Water Conservation Board (CWCB), sponsored Phase II of a groundwater investigation of the Missouri Heights region, a broad plateau located in the Roaring Fork River basin approximately 5 miles northeast of Carbondale, Colorado. The investigation was designed to evaluate the effect, if any, that increased residential development and changing land use patterns have had on the water levels of the local aquifers. The Phase II study involved the establishment of continuous groundwater recorders, development of a new, regional weather station, quantification of land use changes, and review of the region’s general water balance. This report documents the study methods, assumptions, results and conclusions regarding groundwater development in the Missouri Heights region.  The Phase II study was initially completed in 2014; however, the study was extended to gather more data and to confirm the trends and conclusions established in 2014.


The update to the study is available here:

The Basalt Water Conservancy District was formed in 1964 to conserve, develop and stabilize supplies of water for domestic, irrigation, manufacturing, and other beneficial uses within those parts of Eagle, Garfield, and Pitkin counties included within its boundaries. In furtherance of these goals, it filed an application for change of water rights and for approval of plan for augmentation, including appropriative right of exchange, in 2002 in Case No. 02CW77. The District received its final decree from the Water Court in this case in 2012 (“Decree”).

This Decree approved a plan for augmentation (“Plan”) which permits the District to directly include certain water users into the Plan, so long as those users meet certain criteria. In order to be included in the Plan, however, the District must provide notice of applications, including all application materials, on this website at least forty days prior to consideration at the District’s meeting. The District’s Board of Directors typically meet on the second Tuesday of every month. Specific meeting dates are posted below. Interested parties may file comments with the Division Engineer within thirty days of the posting of notice on this website. Comments may be mailed to the Division Engineer at:
