During September and October, anglers will receive an additional payment of $300 for each harvested brown trout containing a PIT tag. PIT tags are a small (7 mm) tag that researchers use to uniquely identify each fish and to estimate population size, etc. Pictures of pit tags are located on the brown trout signage at the Lees Ferry Boat Ramp.
Anglers are encouraged to help reduce the growing population of brown trout in the Colorado River below Glen Canyon Dam. Brown trout spawn during fall and winter months when they begin to move into shallow waters. This is a great time to catch brown trout and focus on fishing gear and techniques that enhance the angler’s experience. Although brown trout can be found throughout the river below the dam, most have been harvested from the dam down to approximately 4-miles upstream from the Lees Ferry boat ramp.
Unfortunately, the brown trout population between the dam and Lees Ferry has steadily increased since 2014. As adults, brown trout feed on other fish, threatening downstream native and endangered fish species. The goal of this program is to determine if the Incentivized Harvest by anglers can help manage and reduce the number of brown trout. This management option was highly favored during public review of potential management tools when compared with intensive mechanical removal efforts or disturbance activities during the spawning period.
The Glen Canyon Conservancy is helping administer the Brown Trout Incentivized Harvest Program and will send participating anglers a check at the end of each month.
