Age and Growth Characteristics of Trout in Washington High Lakes

Bob Pfeifer

Age and growth characteristics are reported for rainbow trout, cutthroat trout, eastern brook trout, brown trout, and lake trout from high lakes in Washington’s Cascades mountain range. Samples were collected between the mid-1970s and 1999. Samples of known age were available from 117 rainbow trout and 53 cutthroat trout, primarily in the western side of the Alpine Lakes Wilderness Area. Overall, 2,930 samples were collected primarily from counties and areas north of Mount Adams.

High Lakes Fishery Management Program

This is the first comprehensive review and summary of the management of the high lake fishery in Washington State. Its purpose is to document the history, goals, and unique aspects of this program, as well as angler participation in, and economic value of the fishery. It identifies the number and general characteristics of the lakes that are managed for a fishery, as opposed to the many waters that are left in a natural state. The report provides documentation of the Washington Department of Fish and Wildlife’s (WDFW’s) current high lake management practices. WDFW seeks to increase public awareness and understanding of the high lake fishery program; this report documents how WDFW meets the public’s need and desire for this form of recreation, while protecting other wildlife and wilderness values. Finally, the report is the first comprehensive preparation of recommendations on how to improve WDFW’s high lake management program.
