Item Open Access An environmental inventory of a portion of Piceance Basin in Rio Blanco County, Colorado(Colorado State University. Libraries, 1971) Colorado State University. Environmental Resources Center, author; Cameron Engineers, authorItem Open Access Irrigation development potential in Colorado(Colorado State University. Libraries, 1977) Whittlesey, Norman K., author; Colorado State University. Environmental Resources Center, publisherThe primary purpose of this report is to project potential crop production levels for irrigated agriculture in Colorado. This report estimates the gains in water supply that could be achieved by improving the efficiency of water use on currently irrigated lands. For this purpose, improved irrigation management, ditch lining, and new irrigation systems were considered as means of increasing water use efficiency in agriculture. The state of Colorado was divided into eight regions for purposes of this study. These regions correspond to river subbasins within the state.Item Open Access A guide to Colorado water law(Colorado State University. Libraries, 1978) Fischer, Ward H., author; Ray, Steven B., author; Colorado Water Resources Research Institute, Colorado State University, publisherItem Open Access Network analysis of raw water supplies under complex water rights and exchanges: documentation for program MODSIM3(Colorado State University. Libraries, 1984) Labadie, John W., author; Pineda, Andrew M., author; Bode, Dennis A., author; Colorado Water Resources Research Institute, publisherThe increasing complexity of water supply planning and management for municipalities such as Fort Collins requires use of computer models as an aid for City Staff and Water Board members. a generalized model called MODSIM3 is documented herein which allows a wide variety of water supply evaluations in a complex water rights structure that includes direct flow rights, storage rights, and water exchange possibilities with other users. MODSIM3 includes certain improvements over two earlier versions of MONSIM in being able to include both physical and accounting transfers of water for exchange purposes.Item Open Access Colorado's water: climate, supply and drought(Colorado State University. Libraries, 1990) Colorado Water Resources Research Institute, authorItem Open Access 1990 floods in the U.S.: a descriptive report of flooding in the Southern States(Colorado State University. Libraries, 1990) Clark, John R., author; Colorado Water Resources Research Institute, publisherThe year of 1990 will be remembered by many in the southern United States as a record year for extreme rainfall and disastrous flooding events. People in Alabama and Georgia recall the floods of 1929 and 1961 as almost as significant. Residents in Oklahoma, Arkansas and Texas will speak of 1927, 1945 and 1989 as being memorable. The year 1990 is significant because rarely, if ever, have devastating rainfall and runoff events occupied so many people in so many states across our country for so long a time period. This report is a summary of information of these events, bringing together the causes, responses, first-hand impressions and commentary of the widespread flooding of 1990. It will introduce relationships observed between hydrologic and social influences apparent in these memorable and significant events. Data sources are made available in the library of the Colorado Water Resources Research Institute for in-depth review and further study.Item Open Access Delph Carpenter, father of Colorado River treaties: text of Governor Ralph L. Carr's 1943 salute to Delph Carpenter(Colorado State University. Libraries, 1991) Carr, Ralph L. (Ralph Lawrence), 1887-1950, author; Carpenter, Delph, author; Grigg, Neil S., author; Colorado Water Resources Research Institute, publisherThe rulebook for the Colorado River is the 1922 Colorado River Compact, a document now nearly 70 years old. Time said, "This critical document facilitated both the astonishing development of the West and the problems that followed as a result." The centerpiece of Delph Carpenter's career was the Colorado River Compact and the acknowledgement of his role came from no less a person than President Herbert Hoover. Hoover's admiration for the work of Carpenter is evident from the two letters included in the booklet. Not only was Delph Carpenter an institution in the field of western water law; he left a legacy through his son Donald, who became an attorney and accompanied his father to many water meetings including trips to see President Hoover. When Delph Carpenter became disabled with Parkinson's Disease but struggled to continue his work, his son Donald took care of his father's personal needs while he continued to work on the interstate water treaties. At the time that Governor Ralph Carr delivered the speech which is reprinted here, Donald was on the East Coast awaiting shipment to Europe in World War II. Ex-President Hoover arranged for Donald to attend the banquet. Donald Carpenter went on to a distinguished career as a district judge in Greeley, including presiding over the water court. Today's students of water resources management will benefit from the study of this speech and the vision held by Delph Carpenter and his peers about Western water management.Item Open Access Water research in the Rockies: a historical retrospect: Rocky Mountain Hydraulic Laboratory and the Rocky Mountain Hydrologic Research Center, Allenspark, Colorado(Colorado State University. Libraries, 1996) Marsh, Jill, author; Flug, Marshall, author; Colorado Water Resources Research Institute, publisherThis report provides a history of the Rocky Mountain Hydraulic Laboratory (RMHL), its founder, purpose, formation, early research conducted, and recent developments.Item Open Access Organizing for endangered and threatened species habitat in the Platte River Basin(Colorado State University. Libraries, 2003) Freeman, David M., author; Epperson, Annie, author; Lepper, Troy, author; Colorado Water Resources Research Institute, publisherThis study is an attempt to capture the essential shape of multiple sets of negotiations that have been on-going for more that a dozen years in the Platte River basin.Item Open Access Stretching urban water supplies in Colorado: strategies for landscape water conservation(Colorado State University. Libraries, 2004) Barta, Rachel, author; Ward, Robert, author; Waskom, R. M. (Reagan McTier), author; Smith, Dan, author; Colorado Water Resources Research Institute, publisherThe purpose of this study was to enhance the dialogue between municipal water providers and the green industry by identifying strategies for landscape water conservation that are acceptable and reasonable to both industries. Each strategy was explored in depth for purposes of extracting conservation options that may be beneficial in Colorado. A review of price and non-price strategies and an analysis of the advantages, disadvantages, and effectiveness of strategies are provided in the study.Item Open Access Colorado high plains irrigation practices guide: water saving options for irrigators in eastern Colorado(Colorado State University. Libraries, 2004) Schneekloth, Joel, author; Broner, Israel, author; Waskom, R. M. (Reagan McTier), author; Barta, Rachel, author; Colorado Water Resources Research Institute, publisherThis report summarizes irrigation practices that offer potential water savings at the field or farm level, providing a summary of the documented water savings options for irrigators in Colorado. The report provides a significant amount of detail regarding what options are available for water conservation, how these options are used to conserve water, and expected water savings that can be achieved through various irrigation conservation practices. On a field or farm scale, there are a number of water conservation practices that may be employed to reduce the amount of water pumped or diverted. Due to the site specific nature of agricultural operations, no one set of practices is universally appropriate. Irrigators must evaluate their cropping system, management constraints and water supplies to determine the right mix of irrigation practices for their farm or ranch.Item Open Access Irrigation, settlement, and change on the Cache la Poudre River(Colorado State University. Libraries, 2005) Laflin, Rose, author; Colorado Water Resources Research Institute, publisherThe Cache la Poudre River drains 1,890 square miles of land in the Mummy and Never Summer ranges in Colorado and Wyoming. It begins on the Continental Divide, flows through mountain canyons on the eastern side of the Rocky Mountains in Colorado and onto the plains, before joining the South Platte River. American settlers first diverted the Poudre’s water into ditches and canals to facilitate irrigation on the plains in the early 1860s. This examination of the water delivery system of the Cache la Poudre – which includes small ditches, large canals, and reservoirs – documents the use of the water for agriculture, municipal, industrial and recreational use. A synthesis of information from public sources such as university libraries, local history archives, the Colorado State Archives, the Colorado State University Water Resources Archive, and the Denver Public Library’s Western History Department, this “environmental history” addresses the development of the water delivery system; the impact of the delivery system on society, economy, laws, technology, hydrology, and the environment; and some attention to Colorado Water law.Item Open Access Agricultural chemicals & groundwater protection in Colorado, 1990-2006(Colorado State University. Libraries, 2006) Bauder, Troy Allen, author; Waskom, Reagan, author; Wawrzynski, Rob, author; Mauch, Karl, author; Naugle, Greg, author; Colorado State University, Cooperative Extension, publisherItem Open Access Meeting Colorado's future water supply needs: opportunities and challenges associated with potential agricultural water conservation measures(Colorado State University.

Libraries, 2013) Wawrzynski, Rob, author; Waskom, Reagan, author; Bauder, Troy, author; Ross, Andrew, author; Wardle, Erik, author; Mauch, Karl, author; Colorado Water Institute, publisherThe Agricultural Chemicals and Groundwater Protection Program was created during the 1990 legislative session and took effect on July 1, 1990. The Program's purpose is to reduce negative impacts agricultural chemicals have on groundwater and the environment by preventing groundwater contamination before it occurs through improved agricultural chemical management. Agricultural chemicals covered under this legislation include commercial fertilizers and all pesticides. This report summarizes the efforts of the Agricultural Chemicals and Groundwater Protection Program since inception and provides an overview of activities and monitoring data.
