North Platte service station
No full textColor slide of a blue painted gas station built to resemble a small cottage with a stylized pitched roof and chimney on the front of the building. A simple two stall garage stands to the left of the building with a white sign that reads "The House of Lindsay Soft Water" in blue capital letters" above the garage doors. Handwritten caption by Chester H. Liebs reads "North Platte NB"

OPPORTUNITY COSTS OF WATER LEASING: IRRIGATION, INSTREAM FLOW, AND WETLAND CONSIDERATIONS IN THE LARAMIE BASIN, WYOMING
No full textFlood irrigation in the Laramie Basin of southeast Wyoming has created many wetlands that rely directly on irrigation inputs for water. The Laramie Basin is a proposed water source for enhancing Platte River instream flows, to the benefit of endangered cranes, terns, plovers, and sturgeons. Increasing irrigation efficiency, or retiring irrigated lands would transform Laramie Basin agriculture and cause a high fraction of the Basins wetlands to be lost. This study explores the limitations of traditional water transfer tools when regional instream-flow requirements compete for water with local irrigation-dependent wetlands. A rotating short-term water lease program is proposed. The program would allow Laramie Basin producers to contribute to instream flow without causing permanent wetland damage or loss. Short-term water leasing programs could allow agricultural communities to contribute to regional environmental water needs without sacrificing local, agriculturally-based ecological resources. An estimate of minimum water costs, advantages and disadvantages of short-term water leasing are discussed.Resource /Energy Economics and Policy,

No full textEvaluation of SAMSON for use in a South Platte decision support system
No full textDecember 1996.The South Platte River basin is a tributary of the Missouri River. Three states share the basin (Colorado, Nebraska, and Wyoming), with most of the basin in Colorado (79 percent). Colorado's population has been growing rapidly, especially in Front-Range cities, increasing the demand on water resources in the basin. Highly productive plains agriculture is also a substantial user of water resources and new uses also can be expected for wildlife and recreation. A decision support system (DSS) is being planned by the State of Colorado for water management in South Platte River Basin. Anticipated needs of the system include data development and some model development specific to the South Platte. Due to the unique characteristics of the South Platte River Basin, the implementation of this framework is expected to be slightly different from other basins in Colorado. The SAMSON (Stream-Aquifer Model for Management by SimulatiON) Model, developed in the 1980s specifically for the South Platte River Basin, has been recommended by past studies for use in a South Platte DSS. This report provides and analysis of the current SAMSON model. The conclusions of this report recommend that SAMSON in its present form not be used as part of a DSS, largely due to recent developments in modeling philosophy, application, and use. SAMSON proved the entire South Platte River Basin system could be effectively modeled, and pointed to the priorities for data collection and development. Components of SAMSON could be part of future DSS systems, but they should be separated into individual modules and evaluated individually against existing models. In summary, the analysis of SAMSON clearly show the need for a modular and data-centered approach for a South Platte DSS.Grant no. 14-08-0001-G2008/5 Project no. 09; financed in part by the Department of the Interior, U.S. Geological Survey, through the Colorado Water Resources Research Institute
