The legislature recognizes that, if funding for planning, design, evaluation, construction, and operating expenses is provided by a public utility that diverts water for beneficial public use, and if the performance of the spawning channel meets the production goals described in RCW
77.100.120, the spawning channel project will serve, at a minimum, as compensation for lost sockeye salmon spawning habitat upstream of the Landsburg diversion. The amount of funding to be supplied by the utility will fully fund the total cost of planning, design, evaluation, and construction of the spawning channel.
