In a way this is a passionate topic for me, as my goal is share my passion and help others become successful, helping them meet their own angling endeavors. Pretty hard to do that if they cannot find out where the fish even are they want to target.
The majority of the lakes I fish, and film on, are public waters, State Parks, very heavily fished and used recreationally. There is nothing secret about where the fish are, what fish are in there.
A quick "google" search will tell a prospective angler what fish are available at a certain venue. 95% of the time, someone, somewhere, is going to have posted something related to that species and a particular body of water.
A search on Banner Lakes, Colorado, Northern Pike, provides 10 posts, first page, with details on these fish at this location, again, not a huge secret there. I didn't even bother looking at page-2 results.
I got a few emails about my videos last year featuring Adams County Fairgrounds, the carping episodes, on the topic of "burning" secret carp spots. C'mon guys, the locals called the spot I fished, "carp point", it's not a secret.
I even was flattered when another angler posted his own short video, a few days later, fishing that exact same spot... Fins-Up to him for getting out there, sweet corn on a hook and trying to bank some monsters for himself.
I agree that it would be great if more anglers would share their knowledge and tips to success, you can do this without providing a GPS map and coordinates to where you catch your fish from.
That's what FishExplorer is about, sharing the passion and helping others - obviously, with plenty of self promotion and display of captures!
Yes there are some venues I fish for my own pleasure, do not film or if I do, don't advertise in an obvious manner the location.
Hey, we all have our secret honey holes.
