and aquatic habitat loss, and water pollutant discharges. The resulting

ecosystem impacts on organisms and their life cycles. on rare and endan-

gered species. and on the existing food chains noted in the table suggest

a framework for research needs which relates activities to ecosystem ef-

fects in specific regions of the Upper Colorado Basin. At present. ura-

nium mining and milling. hydroelectric power generation, and fossil

fuels production are already well developed in certain areas. As needs

for new energy sources become more immediate, the effort will turn to-

ward the less easily developed fossil fuels such as deeper coal seams,

tar sands and oil shales in geographical areas located by Flaming Gorge

Darn, in the Uintah-White River basins and the San Juan River Basin, and

in the high plateau areas neaT Lake Powell. As indicated by table 8, the

consequences of such development on life cycle and fish populations can

be expected to be widespread in the upper basin.

In broad basin-wide terms, then, general categories of research needs

are associated with environmental problems arising from energy and relat-

ed development. While more specific research needs are included in subse-

quent chapters. table 9 presents a range of general research areas that

are important for understanding the consequences to fish and wildlife of

man's intervention in the Upper Colorado River Basin to develop energy

resources. These research needs range from effects on stream nutrient

loading and aquatic food chains to effects on stream quantity and qual-

ity.

The mineral, energy, and agricultural activities in the basin are

all dependent on the availability of water of sufficient quantity and

quality. Yet this same water is also vital to sustaining the natural
