DECIDING THE FATE OF RESERVOIRS: THE ROLE OF DOWNSTREAM RIVER RESTORATION OBJECTIVES
 
The multiple objectives of reservoir management must now be broadened to include the requirements for maintenance of the downstream river environment. Downstream river management is not a self-evident objective, however. One goal might be to consider the reservoir and the downstream river as an integrated ecosystem in which reservoir operations are used to maintain a wide range of downstream river resources including tailwater fisheries and other ecosystem components that may flourish because of a dam's existence. A very different goal might be to focus downstream river management on restoration of those ecosystem components that were distinctive of the river's condition prior to dam closure. The former goal implies that maintenance of a reservoir's ecological integrity is a societal value, but the latter goal does not. Thus, the decision to pursue active managment and study of reservoir limnology partly depends on the management goal for the downstream river. In some cases, the ultimate decision of society may be the elimination of the reservoir. These decisions, and the resources trade-offs that they imply, are under active consideration in the Colorado River basin.
