A single series of water flow measurements were conducted in the Arkansas River Basin. Measurement were made of water flow from the confluence of Lake Creek and the Arkansas River to the headgate of the Bessemer Canal. Investigation of seepage and conveyance losses tended to confirm previous estimates of a 12% conveyance charge from the Twin Lakes.

Aluminum irrigation pipes are commonly used in agriculture in the arid West. The lightweight pipes are thirty to forty feet in length and are designed to be connected, moved, and reconnected by hand in irrigated areas during growing seasons. High voltage lines (7200 or 7620 volts) supply power to the irrigation pumps, and are typically suspended twenty to thirty feet above ground. Electrocutions usually occur around the periphery of irrigated fields...

The purpose of this task is to identify a consumptive use methodology suitable for estimates of crop evapotranspiration in southwest Colorado. It includes a review and discussion of the more common predictive equations and sample calculations using measured and derived climatic data at a weather station in the project area. Mean data are used for all calculations except precipitation in which a 60 percent recurrence interval is used in effective...

This Watershed Plan Environmental Assessment is to improve the surface and groundwater quality by reducing the agricultural contribution of heavy metals salts sediment, and nitrate contamination This will be accomplished through accelerated technical and financial assistance for the installation of on farm land treatment measures. The measures are to reduce contaminants in the groundwater surface water and the Arkansas River to an acceptable level...

Publisher's description: It is no coincidence that human civilization sprang from river valleys and floodplains. Access to water has been crucial to our food security and to the growth of cities and industries. In recent times, the fortunate have come to take water for granted: endless supplies seem to flow from dams, reservoirs, wells, and diversion projects. But for decades now we have wasted and mismanaged the world's water. Engineering projects,...

"Our global economy is outgrowing the capacity of the earth to support it, moving us ever closer to decline and possible collapse. We have lost sight of how vast the human enterprise has become. A century ago, annual growth in the world economy was measured in billions of dollars. Today it is measured in trillions. As a result, we are consuming renewable resources faster than they can regenerate. Forests are shrinking, water tables are falling, and...
