Lower baker dam seepage reduction project
WebThe most likely cause of seepage reduction is considered to be migration of fracture infill material gradually sealing seepage exit points. Investigation of the seepage problem in 2001 indicated that an open zone was present under the dam and nontronite clay infill in the same fracture was eroding. If erosion were to WebJun 23, 2014 · The Lower Baker Dam, completed in 1927, and the construction of the Upper Baker Dam in 1958 blocked salmon and steelhead from reaching vital freshwater habitats. Downstream passage, in particular, severely impacted the survival of these fish runs, and by 1985, a mere 99 adult sockeye salmon returned to the Baker River.
