The “Surviving Against the Odds” Interpretive Field Station at Wenatchee Confluence State Park
The interpretive sign reads,
Surviving Against the Odds
Millions of young salmon migrate from the tributaries of the Columbia River to the Pacific Ocean. Only a small fraction mature and return to their native stream to spawn. Most perish from natural predation, fishing, and loss of habitat caused by human activities.
Even under pristine natural conditions, only a few more adults return than are needed to replace their parents and sustain the population. Human activities have upset this delicate balance, so that salmon population have declined.
Chelan County Public Utility District No. 1 funds research and hatchery programs to increase fish populations. The goal of research is to produce vigorous, healthy fish. Hatcheries provide safe conditions for eggs to hatch and for young fish to feed and mature until they can be released in the wild to begin the migration cycle again.
