Stream of Dreams in British Columbia thinks so, and a lot of wooden fish and some , school kids later, they have some intriguing results to show for their effort. Recent interest in flood control and restoration strategies in the Chehalis River Basin has increased the need to understand the current status and ecology of spring Chinook salmon. Based on the extended period between freshwater entry and spawn timing, spring Chinook salmon have the longest exposure of all adult Chinook salmon life histories to the low-flow and high water temperature.
