Description

Kokanee (Oncorhynchus nerka) are the landlocked form of sockeye salmon, found in several Wyoming and Colorado lakes and reservoirs. These beautiful fish provide excellent sport fishing opportunities and spectacular fall spawning displays.

Kokanee have a streamlined, silvery body with a bluish-green back. During spawning season (fall), they develop brilliant red coloration with green heads, creating one of nature's most dramatic transformations. Non-spawning fish maintain their silver appearance.

These fish are an important forage species for larger predators and support significant recreational fisheries in many western reservoirs.

Habitat

Kokanee are found in large, cold-water lakes and reservoirs:

Lakes and Reservoirs

Thrive in large reservoirs including Blue Mesa Reservoir, Flaming Gorge, and other deep, cold-water impoundments. They prefer open water areas with access to deep, cold water.

Preferred Conditions

Kokanee require cold water temperatures (45-55°F / 7-13°C) and follow the thermocline during summer. They are pelagic fish that roam open water in search of zooplankton.

Behavior

Kokanee exhibit unique behavioral patterns:

Feeding Behavior

Primarily feed on zooplankton, making them challenging to catch on flies. They also consume small aquatic insects and will occasionally take small flies and lures.

Seasonal Patterns

Spring: Shallow water (10-30 feet) as water warms, good fishing near tributary mouths

Summer: Deep water (40-100 feet), following zooplankton concentrations

Fall: Spawning runs into tributary streams (September-November), brilliant red coloration

Winter: Deep water, reduced feeding

Spawning

Spawn in fall (September-November) in tributary streams or along lake shores with gravel. Like all Pacific salmon, kokanee die after spawning, creating spectacular spawning displays.
