Yes there are still musky in the crow lake and a few in the river but you will be hard pressed to get into one unless you find a way around the pike.
story is the ministry ( accidentally) dropped 20thousand pike into the river instead of musky. Truth is the closing of the musky hatchery just west at what was deer lake but is now cordova made a huge impact on how musky were managed and the ministry may have been responsible for the severe decline in musky populations all over Ontario by replacing with a more invasive pike population anglers have unfortunately become accustomed to this new smaller slimmy stinky version . A new musky hatchery was opened at codrington but never lasted long. Bottom line ministry is responsible for Ontarios declined musky population.
