<br />may have to be curtailed, unless corH\ct.ivC' ,actioil is, Lak,'n soon. <br />Similar damages will result to the Forest unless additional facilities, <br />i.e., campgrounds, picnic areas, trails, etc. are providc'd to prevent <br />overcrowding of the existing facilities. <br /> <br />(3) Institutional Issues. Approval of the Federal claims for <br />water rights as of the date withdrawal of the National Forests, and <br />their quantification, will assure the Rio Grande National Forest of <br />an adequate water supply to meet the requirements of the recreation <br />uses. <br /> <br />(4) Financial Issues. Failure to obtain Federal and State funds <br />for improvements and the operation and maintenance of the National <br />Forests and recreational facilities in the Problem Area will result <br />in the adverse effects given in (2) Related Land Issues, above. <br /> <br />Problem Area 3, ASA 1301. <br /> <br />(1) Water Issues. The average annual withdrawal of water for <br />irrigation in the area is 175.9 MGD (197,060 a.f.) short of satisfying <br />the irrigation requirements for a full supply. The value of an acre- <br />foot of supplemental irrigation water is estimated to be $27.80 on- <br />farm, and $195.56 on-farm, direct, induced and stemming from value. <br />(See Problem Effects and Implications for Problem Area 1 in Colorado, <br />ASA 1301 for explanation). Thus, the increased on-farm income would <br />be $5,478,270 in the area, and the on-farm, direct, induced, and <br />stemming from increase would be $38,537,050. An incre,ase in the <br />amount in the economic activities of this economically depressed <br />area would be invaluable. Primarily, it would provide jobs for the <br />large unemployed labor force and bring their incomes above the pov- <br />erty level. The health and welfare of the area and region would be <br />materially benefited. <br /> <br />Maintenance of higher stream flows on the Rio Grande from above <br />Monte Vista to the Colorado-New Mexico State line, a distance of <br />about 60 miles, would provide many benefits. It would greatly im- <br />prove the fish and wildlife habitat and dilute the salts in the <br />river from domestic and agricultural wastes. About 20-25 miles of <br />mountain streams would be returned to near pristine condition by <br />elimination of the contamination of the tributary stream on Alamosa <br />River and in the Platoro region by mine waters. <br /> <br />(2) Related Land Issues. MCC has reported that the annual <br />upstream and downstream flood damages in 1975 for ASA 1301 were <br />urban, $77,000; non-ruban (agricultural) $1,269,000; non-urban <br />(other) $262,000. Most of these damages occur in Problem Area 3 <br />with much of the non-urban (agricultural) resulting from floods <br />on the Rio Grande and major tributaries. Floods are a health <br />hazard, especially in rural areas where domestic wells are <br />frequently contaminated by flood waters. <br /> <br />73 <br /> <br />, : ,r "< <br />\...' ....' (,.... .
