<br />~ <br />lot,,",, <br />~ <br /> <br />" <br />., <br /> <br />Extreme low T.crnperatures are possible in February, as shown from <br />1989 through 1991. Fruit trees and grapes succumbed to the cold <br />during that time. In 1991, the temperatureswere.colder than. <br />normal (April/May) in. the spring and delayed corn planting and <br />growth by about two weeks. Harvesting was delayed by several weeks <br />because of a cold and wet fall (refer to climatic summary in <br />Appendix A). In 1992, the months of May, October, and July were <br />wetter than normal; whereas April, June, September, and December <br />were dry. <br /> <br />~~;;:}: <br />'.;:~;. <br /> <br />5. objectives Of ~he M'E Progr~ <br /> <br />The 'objectives of. the .M&E Program are to measure and quantify. the <br />effects of improved on-farm irrigation systems and practices being <br />installed in the Grand Valley to reduce salt loading to the <br />Colorado River. . <br /> <br />The goals of the Irrigation M&E Program are: 1) to'measur~, all <br />irrigations for the entire season on selected fields, 2) qUantify <br />deep percolation reduction resulting from implementing irrigation <br />system and management improvements, 3) evaluate on-farm irrigation <br />system performance and recommend design improvements based on <br />actual system performance, and 4) identify management follow-up <br />needs and directions.' <br /> <br />The'-~aets on wildlife habitat due to the cost-sharing of salinity <br />practices were monitored and evaluated between 1983 to 1988 (Refer <br />to "Wildlife Habitat" portion of the 1986, 1987 a.nd 1988 Annual M&E <br />Reports) as outlined in the 1983 Grand Valley Monitoring and <br />Evaluation Plan, pages 11 to 13. Acres of vildlife habitat <br />developed under the CRSC Program continue to be tracked and <br />recorded. Wildlife habitat acres under the GVSP and GVSP-Long Term <br />Agreement (LTA) programs have been recorded and accepted (see <br />Section III).' ' <br /> <br />~t:'..r.: <br /> <br />Economic impacts, potential salinity reductions and soil salinity <br />levels are being evaluated. The M&E data will help determine <br />program effectiveness in reducing the salt load to the Colorado <br />River and will help direct future salinity program activities. <br />This is contained in Section IV of this report. <br /> <br />This report is divided into three parts dealing with each of the <br />monitoring disciplines: Hydrosalinity, Wildlife, and Economics. <br />Each discipline is at a different level of project implementation <br />and data collection, therefore, each is dealt with separat~ly in <br />this report. <br /> <br />" <br /> <br />4 <br />
