Have opportunity costs of foregone recreation benefits and hydro- <br /> <br />generation been incorporated in the most curretn benefit-cost <br /> <br />ratio calculations? Yes: Recreation benefits claimed by the project <br /> <br />are the ihcrease in 'opportunities or benefits over those evaluated <br /> <br />" <br /> <br />in the "without project situation," except for minor uses in the reser- <br /> <br />voir basin. Hydroelectric generation at storage units ot Colorado <br /> <br />River Storage Project has been based and projected on flows of the <br /> <br />Colorado River and tributaries depleted over time consistent with <br /> <br />allocations under compacts governing the use of water. The benefit- <br /> <br />cost ratios of this project include cost assignments of mainstem <br /> <br />reservoirs equal to the proportionate use of such reservoir essential <br /> <br />to maintaining compact flows at Lee Ferry. <br /> <br />10.
