The restored <br />cross-drainage interceptions. provided by the Big Sandy Creek Diversion <br />Structure. and reduced water losses. from other project improvements, <br />will add 6,740 acre-feet to the average year water supply. This water <br />will irrigate an additional 2,620 acres for a project total of 24,000 <br />acres, <br /> <br />WATER QUALITY <br /> <br />Water quality of the Arkansas River near Caddoa has been analyzed since <br />1942 and. during the irrigation season. the quality has remained much <br />the same, The quality of the river water for irrigation can be classed <br />as excellent as far as sodium and boron concentrations are concerned; <br />however, the salinity content can be classed as high. These high sali- <br />nity waters have been used for irrigation by the Amity System for near- <br />ly 100 years with the result that the existing irrigated soils have <br />adequate permeability and subsurface drainage to maintain crop yields, <br /> <br />Water quality data is available in "Water Resource Data for Colorado". <br />Part 2, Water Quality Records, published annually by the Department of <br />Interior. Geological Survey. <br /> <br />The rehabilitation of the existing system will not change the water qua- <br />lity of the Arkansas River nor of the groundwater underlying the system, <br /> <br />3-3 <br />
