evaluation process. The US Fish and Wildlife Service (F &WS), US Geological Survey <br />(USGS), the Colorado State Historic Preservation Officer (SHPO), and the Colorado <br />Division of Wildlife (DOW) have been and will continue to be contacted. <br />Purposes to be served by the project are agricultural water management and watershed <br />protection. Specifically, this project has been formulated to improve both surface and <br />groundwater quality, reduce irrigation induced erosion to acceptable levels, and more <br />effectively conserve and use available water supplies by improving on farm irrigation <br />water management thus reducing irrigation runoff. Irrigation induced erosion will be <br />reduced in the treatment area on 1,000 acres now eroding above "T ", the maximum <br />rate acceptable when attempting to maintain the productive capacity of the soil <br />resource. Poor water quality from selenium, sediment, heavy metals, and salts in wells <br />and drains will be improved in the watershed as well as in Cheraw Lake, Horse Creek, <br />and the Arkansas River. Better on farm irrigation water application will occur on 9,000 <br />acres. These efforts will help move irrigated agriculture closer to being able to achieve <br />the irrigation effectiveness, which existed in the 1950's. <br />The Recommended Plan (RP) includes concrete ditch lining, underground pipe, gated <br />surface pipe, land leveling, underground drainage, polyacrylamide, and wetland multi- <br />use ponds, wetland creation, wetland enhancement, irrigation water management, <br />nutrient and pest management, and conservation tillage. The estimated cost of the <br />recommended plan alternative is $2,386,200 with $1,597,900 in PL -566 costs. <br />20 <br />
