"This report consists of engineering details, statistics, individual borehole histories, and logistics for the 27 boreholes drilled in the project. Geophysical logs are included." (from Introduction)

From purpose and scope: The primary purpose of the study was to aid in evaluating the waste-load assimilative capacity of the study reach for a minimum mean 7-day low flow and 10-year recurrence interval. The results of this analysis will provide planners and managers in Routt County with information for determining the waste-load capacities of the study reach for possible design and operational alternatives of future wastewater-treatment plants.

From abstract: Large increases in coal mining currently (1979) taking place in the Yampa River basin are expected to continue during the 1980's and may adversely impact both the ground-water and surface-water quality in the basin. One potential source of adverse impact is the dissolution of soluble minerals contained in the overburden material disturbed during the mining. This potential impact was investigated using digital ground-water transport-modeling techniques.

This report studies the geology of mineral deposits in Mount Harris, Pilot Knob, Elkhead Creek, and Daton Peek quadrangles in northwestern Colorado.
