All four species are not present throughout the basin. Nevertheless, water projects that require federal permits or involve federal actions are required to comply with the ESA. In the Colorado Basin, a "programmatic approach" is being taken. In general terms, this means that certain management and research actions are being implemented at a programmatic coordinated level to provide benefits to the species. These actions are done to (1) offset the effects of historic water uses, and (2) to allow for future water use and development. Following is a summary of some of the key elements of the Colorado River Endangered Species Recovery Program. r~ S:\REPORIIWORD PROCESSING\REPORllS6 11-8-04.DOC 6-33
