<br />. <br /> <br />. <br /> <br />. <br /> <br />agencies for establishing flood fight and emergency operations, including traffic re-routing <br />during flood events. The CWCB plans to negotiate a contract with one or more aerial <br />photogramatic firms who will operate on a standby basis. A total of $1 0,000 is requested for this <br />purpose. <br /> <br />CSU Lower Arkansas Cooperative Extension Unit - Lower Arkansas River Water Quality Study <br /> <br />Runoff from certain agricultural areas in the lower Arkansas River valley has a high salt <br />concentration that contributes to the salinity of the Arkansas River at the state line. Working with <br />the local CSU Cooperative Extension Unit, the CWCB has planned to provide up to $45,000 in <br />FY99 funds for phase I of a potentially 3 year project. The project is intended to demonstrate Best <br />Management Practices (BMPs) to improve crop yield and water quality in a demonstration area in <br />the Northeast Prowers Soil Conservation District area near Holly. The object of the study is to <br />demonstrate the economic benefits of using more effective irrigation management practices through <br />improved technology such as cropping patterns, low energy precision application, and other Best <br />Management Practices. <br /> <br />CSU has requested an additional $45,000 in FY 2000 to enlarge the demonstration area and <br />collect data from a wider range of conditions. The expanded project will continue to demonstrate <br />the use ofBMPs to irrigators in the lower reaches of the Arkansas River in Colorado. These BMPs <br />include the use of surge irrigation and center pivot irrigation with drop type drag hoses. Installation <br />of drain tiles and cleaning of existing drainage ditches will also continue. The effect of these <br />irrigation methods on soil salinity and on the water tables in the surrounding areas will be monitored. <br /> <br />5 <br />
