Alternative C Pro's
o Infringement on State water law or interstate compacts would be
eliminated.
Alternative C Con's
o As discussed in Alternative A, the need far any replacement water at
all is arguable. _.
o Cost of available water will increase. Cost will be borne by people.
LONG-TERM IMPLEMENTATION OF ESA SEGTI4N 7
Common to any alternative for long-term implementation is the Head for further
study. More field data are required to develop the necessary tools to define
impact and conservation measures.
Alternative A
One approach would be continuation of the current practice of requiring "Windy
Gap" payments and defining conservation measures on a case basis for each
Section 7 review.
Alternative A Pro's
The discussion for Short-Term Alternative A applies.
Alternative A Con's
The discussion for Short-Term Alternative A applies.
Alternative B
Develop a plan_to implement the recovery of the listed fishes. This could
involve definition of locations in the river System where fish populations
should be established and then taking steps to establish such populations.
Such steps could include:
o Purchase of specific storage for release for instream needs.
o Construction of reregulatory dams to control flows at optimum levels.
o Construction of temperature-modification structures on reservoirs to
increase habitat suitability (such as Glen Ganyon). .
