An Underwater Winter

January 14, 2014 Posted by: Masaki Mizushima

As Lake Brooks and Naknek Lake freeze over during the Alaska’s long, cold winter the Brooks River continues to flow. Its currents carrying wind-swept white spruce trees and icy sludge downriver. However, beneath the truculent waters, Brooks River is alive with life.

 

Dynamics of the Brooks River Sockeye

July 27, 2013 Posted by: Michael Fitz

In winter, ice and snow cover much of Katmai’s landscape. Salmon fry bide their time waiting to become smolt and run to sea. Later in the year and soon after the smolt depart, much larger salmon are returning from the ocean. In late June, schools of silvery and energetic fish begin to pulse through the river. During August and September, the Brooks River is dotted with ruby-colored jewels digging nests and fighting for territory. Soon after, the waters of Katmai begin to quiet again. The salmon have spawned and most are dead. Eggs are quietly incubating. These are extreme contrasts, but the Brooks River is a dynamic place. Maybe nothing else better illustrates this than the annual sockeye salmon run--a powerful example of change, adaptation, and instinct.
