Distribution of bed sediment on Clear Creek after removal of Saeltzer Dam Saeltzer Dam was removed from Clear Creek in October 2000 to restore ten miles of upstream habitat access to spring run chinook salmon and steelhead trout. Since the dam removal, an estimated 50,000 cubic yards of sediment has eroded from the banks and channel at the former dam site. Some of the eroded sediment has been deposited downstream on Renshaw’s Riffle, a stretch formerly known for its spawning habitat, aggrading the bed up to 2.5 ft. To evaluate characteristics of the sediment deposition, we performed roughly 60 pebble counts and created a facies map for a 1.43 mi stretch downstream of the former dam site. We created maps in ArcMap GIS using the data to depict changes in gravel bar location, the d50 (the... Categories: Publication; Types: Citation The removal of Saeltzer Dam on Clear Creek : an update In October 2000, Secretary of the Interior Bruce Babbitt and California Secretary of Resources Mary Nichols joined in a symbolic ceremony to begin the removal of the 90-year old Saeltzer Dam on Clear Creek in northwestern California, a long-known barrier to fish migration. The removal of Saeltzer Dam was intended to benefit populations of federally listed spring-run chinook salmon and steelhead trout by providing access to approximately 10 miles of upstream habitat. In April of 2003, we visited the former site of Saeltzer Dam. Through surveys, sketch maps, and photographs of the area immediately upstream of the former dam site, we identified a number of changes to creek morphology since removal of the dam and a...

The explicit focus is the development of First Nation sovereignty, authority, and economic self-sufficiency within Canadian federalism. These arrangements have developed in a few situations but the overall pattern is towards diminished intergovernmental cooperation, undermining the extent to which treaties are actually achieving the presumed intentions. Why is this so? The reasons arise in the comprehensive forces within and upon the Canadian federation. Opportunities for First Nation self-determination formed at a time of...
