Fish of Pyramid Lake

Lahontan Cutthroat Trout are the largest species of cutthroat in the world. Anglers every year see fish cross the 20 pound mark with 10-15 pound fish being a reality more frequently. Extensive stocking efforts have been made in the past decades to make Pyramid Lake the amazing fishery we know and love today.

In the late 1800’s western expansion saw the extinction of the Lahontan Cutthroat in most of their native range. Estimated numbers as high as 1,000,000 pounds of cutthroat were shipped annually to mining camps and frontier towns across the west between 1860 and 1920, all from the waters of Pyramid Lake and Lake Tahoe.  In 1905, Derby Dam was constructed on the Truckee River, an attempt to revert water to nearby agriculture. With the only spawning tributary cutoff from the Lake, this resulted in a drop in lake levels by 75 feet that year.  In 1938, Nevada FWP (Fish, Wildlife, and Parks) witnessed the final spawn of the prehistoric Lahontan Cutthroat; it was reported that there were over 200 fish averaging 20 pounds. This was the final straw; exploitation and poor water management saw the end of the mythic Lahontan Cutthroat Trout in Pyramid Lake by 1943. Or so they thought…

Reintroduction efforts were made by the Paiute Tribe starting in the early 1970’s, stocking Summit Lake Strain Lahontan Cutthroat or, as we call them, Summits.  These fish come from a nearby lake with a remaining population of their own strain of Lahontan.  While likely bigger than most cutthroat in the world, these fish were not growing to the historical size and their life span was significantly shorter.  By 1990, a Summit of 8 pounds was worth bragging about.

In the late 1970’s, a biologist named Robert Behnke found fish he believed to be the original strain of Lahontan Cutthroat possibly being stocked from Pyramid Lake back in the early 1900’s by homesteaders trying to populate a creek on their property.  These tiny trout were found in a small creek on the Nevada/Utah border in an area known as Pilot Peak. These fish were genetically identical to the prehistoric fish of the Lahontan Sea, but significantly smaller due to their restricted diet and habitat in this small mountain creek. In 2006, US Fish and Wildlife service partnered with the Paiute Tribe to begin stocking the Pilot Peak strain back into its home waters.  Once these genetics were returned to the Lake, the prehistoric Lahonton Cutthroat Trout had returned home. Tribal fish management began to see fish growing to sizes that had not been in the Lake for generations.  This Pilot Peak Cutthroat strain (or as we call them, “Pilots”) began to gorge on the still thriving Cui-Ui and Tui Chub just as they had 10,000 years ago.

Every year, anglers seem to discover the mythical fish that swims in the back of all our minds.  The reality is, these fish are thriving… and growing, every year the envelope is pushed and a new record seems to hit the beach.  This fishery has returned to what can be considered a historical benchmark and anglers get to experience this apex predator in its native waters as it has been for thousands of years.
