Catchable-sized (10-inch) rainbow, and tiger trout have been stocked and should provide fair to good fishing this summer. Splake, cutthroat trout and Arctic grayling are stocked at a small size and won't be catchable until future years. Tiger muskies have been introduced to prey on the chubs, some reports suggest they've grown upwards of 30-inches since they've been stocked. If you catch a tiger muskie, remember that the harvest limit is just one fish and it must be over 40 inches in length. However, we request that you release any tiger muskies you catch in 2025 so that they can keep the chubs in check, while we work on establishing the fishery. Arctic Grayling have not been stocked in Navajo Lake yet, due to hatchery production limits. 

New Management Plan: Navajo Lake was treated with rotenone in October 2021 to reduce a dense population of Utah chubs that had been significantly impacting trout survival. A new management plan for Navajo Lake was developed during early 2022 with the help of local anglers and officials. The plan intends to provide fishing opportunities for both family and trophy fishing interests, while also addressing the issues of chub competition and overwinter survival. Fish species that will be stocked in the future will include Rainbow Trout, tiger trout, Cutthroat Trout, splake trout, Arctic Grayling, and tiger muskie. It is hoped that multiple predators (tiger trout, splake trout, cutthroat trout and tiger muskie) will help keep chubs from becoming too abundant. Arctic Grayling generally show better overwinter survival in low oxygen conditions and may compete with chubs. Rainbow trout are intended to provide high catch rates, along with tiger trout and grayling. Splake, large tiger trout, and tiger muskie should provide trophy fishing opportunities, with lower catch rates.
