Fish Populations: Adopt-A-River Study

ONP Snorkelers in Quinault River

With more than 4,000 miles of rivers and streams, Olympic National Park is home to some of the most extensive runs of wild salmon, trout and char remaining in the Pacific Northwest. By monitoring the fish populations in four of the parks' rivers, researchers hope to provide valuable information to manage one of the last and best habitats for Pacific salmon and other native fish communities.

"The widespread declines of native fish species in western North America highlight the importance and urgency of understanding trends in fish assemblages from undisturbed habitats," said Sam Brenkman, Chief Fisheries Biologist at Olympic National Park.

In 2010, Washington's National Park Fund provided Olympic National Park with a grant to study and monitor the South Fork Hoh, North Fork Skokomish, East Fork Quinault and Elwha Rivers.

National Park Service and U.S. Geological Survey scientists have monitored fish species for several years. The agencies have conducted snorkel and, more recently electrofishing assessments annually from June to September.

Results of the study will allow for specific management actions including: implementation of more appropriate fishing regulations, evaluation of existing hatchery releases, control of non-native fish species, and prioritization of habitat restoration projects.
