The Blowing Preserve

August 26, 2014 Posted by: Mark Kaufman

Brown bears are the consummate omnivores, and Katmai National Park and Preserve provides an untrammeled land for its most dominant inhabitant to travel in search of food of all shapes and sizes.

 

The Katmai Keystone

August 22, 2014 Posted by: Lacey Thomas

The Bristol Bay region is some of the largest runs of Pacific salmon in the world. Salmon are the keystone species of Katmai National Park. The Brooks Camp area and Katmai in general would not be what it is today without sockeye salmon. Everything present has been built on salmon and their annual migration from vast oceans to Katmai.

 

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.

The only bridge in Katmai spans the Brooks River. All other rivers in the park must be crossed on foot or by boat. Be careful as heavy rains or melting snow can quickly cause the rivers to become uncrossable.
