Quinault Indian Nation used this funding to develop increased smolt sockeye production and run sizes in Lake Quinault by enhancing primary and secondary productivity through the addition of low-level concentrations of liquid fertilizer containing N and P over a 5-year period. 300,886 pounds of nutrient enrichment/fertilizer were added to the Lake by the end of the project. The Quinault Fisheries Division (QFID) monitored the effects by examining primary and secondary productivity and correlating changes to juvenile sockeye growth. Enhancing lake productivity is just one component of the QFID sockeye restoration strategy. Lake Quinault is an ultra-oligotrophic sockeye nursery lake located on the Olympic Peninsula of Washington State. Since 1950, sockeye run sizes, escapements, and harvests have declined significantly. It is hypothesized that marine-derived nutrient inputs from carcasses decreased and negatively impacted lake biological processes at the trophic level, resulting in reduced run sizes. A two-year QFID limnology program identified limiting factors to lake productivity. The loss of marine derived nutrient contributions to lake biological processes limits trophic level productivity and the numbers of smolt sockeye that can be produced. In essence, the lake acts as a "bottleneck" to smolt sockeye production.
