Cultural Resources:
Sites*
1. Lake Canal /Holbrook Ditch Eligible for NRHP
2. Sandhill Site Eligible for NRHP
3. Prairie Dog Site Eligible for NRHP
* None of these sites are located in an area to be affected by the project
Problem Identification:
Major problems identified in the watershed during scoping are:
1. Selenium, Uranium and salt loading is occurring throughout the majority of
. the watershed, impairing offsite water bodies such as the Arkansas River and
Horse Creek.
2. Selenium, Uranium and salt loading is impairing the surface and ground
water within the watershed thereby effecting livestock water as well as fish
and wildlife habitat.
3. Irrigation induced seeps are widely distributed throughout the watershed.
The net effect being reduced production potential of the irrigated cropland.
4. Irrigation water quantity shortfalls.
