Thanks Jay.
As an FYI, I contacted the Quantico Marine Corps Base and was advised that there is NO lake on base that is stocked with snakeheads. Also, couldn't seem to locate any guides or individuals who are consistently on Northern Snakeheads at this time, so will likely switch plans and focus on big smallmouth bass in the Midwest.
The text of the Quantico email is as follows:
Steve,
There is no pond on base that is actually stocked with snakeheads, which are still considered an invasive species. That being said, it seems people have had success catching them in the tidal waters of Quantico Creek, Chopawamsic Creek and Aquia Creek. Of those, only the Chopawamsic is actually on base, but the other two are in the immediate vicinity, and there are a few other creeks with tidal waters in the area.
To fish on base, you’ll need a Quantico fishing permit, which you can get at the main Marine Corps Exchange. Sorry it took me a while to get back to you. Good luck!
