<br />O~1564 <br /> <br />Trinidad Lake provides over 200,000 recreation days annually <br />to the area. The quality of big game hunting in the area is <br />below its potential in that the big game population is also below <br />its potential. The quality of the hiking and cross-country <br />skiing ~xperience is below its potential due to the condition of <br />the forage plant community. <br /> <br />The roads in the project area incur $41,300 in damages <br />annually due to erosion and sedimentation. The railroad is also <br />ueing damaged by flooding and sedimentation. <br /> <br />Ground cover plays an important part in preserving soil <br />moisture. The reduced ground cover is allowing premature <br />depletion of soil moisture. <br /> <br />Information for this project was collected in the field by <br />Soil Conservation Service (SCS) personnel. Seventy-eight percent <br />of the land area within the watershed was inventoried. <br /> <br />Forecasting Conditions <br /> <br />The total erosion per year will probably continue to be at <br />least 170 Ac. Ft. (333,400 tons), which is the current rate. <br />Sheet and rill erosion will contribute an estimated 69 Ac. Ft. <br />(134,400 tons) per year. Gully erosion is expected to be 68 Ac. <br />Ft. (134,200 tons) or greater per year without project action. <br />Erosion from roads will be at a minimum 33 Ac. Ft. (64,700 tons) <br />per year. <br /> <br />The storage capacity of Trinidad lake, which is a multiple- <br />use reservoir, is. and will continue to be reduced at a rate of <br />166 Ac. Ft. per year by sedimentation from the project area. <br />This will reduce recreational and irrigation water supplies. <br />Existing stock water and erosion control structures will also <br />have their expected life decreased due to sedimentation. The <br />accelerated sedimentation from the project area will continue to <br />damage irrigation structures in the future. <br /> <br />The water quality of Trinidad Lake <br />impaired periodically due to sediment. <br />quality of the fish habitat is reduced. <br />recreational value of the lake. <br /> <br />is expected to be <br />During this period <br />This also reduces <br /> <br />the <br />the <br /> <br />The wetlands within the area are being damaged by erosion <br />and sedimentation. Because of the instability of these areas, <br />the natural establishment of high quality wetlands is not <br />anticipated in the future. <br /> <br />The numbers and species of wildlife supported by the area <br />will decrease due to an expected deterioration of habitat. An <br />endangered or threatened species population is not expected to <br />establish itself or be re-established in the future. <br /> <br />21 <br /> <br />
