Re: musky in nepa and guides
If a water has been stocked long enough, and is currently still on the list, the PFBC has probably determined the fingerlings are surviving to adulthood, there is interest in the fishery, and there is a fishable population. Otherwise, the water likely would have been removed from the list.
Whether or not you will catch any fish there, and it will meet your own classification of good, only you can decide that. What I mean is, one group of experienced musky fishermen may fish a water body for the first time and not see a fish, while another group may fish it for the first time and catch 9. If they are experienced musky fishermen, neither group is likely to rate the water body based solely on that trip. They probably look at the weather conditions, moon phase, water temps, water clarity, time of year, what they saw on their electronics, what depths they focused on, whether they trolled or casted, and a number of other variables to help them evaluate the water, and why or why not they had success. Subsequent trips under various conditions, may lead them to consider the water body "a favorite," "fishable under good conditions" or "a dud." And even that report from someone else is only worth so much....I'm sure I have favorites that others might consider duds and vice versa.
Good luck in your quest! My recommendation would be if you haven't musky fished much, hook up with a guide, even if its on a different water....then take that experience closer to home.
There is always a season!
