Does anyone fish the Gatewood Reservoir in Pulaski?

I have never fished for, or caught, a crappie. Fished most of my 45 years, but 99% of my fishing has been in the North Fork of the Holston River for smallmouth.

Just bought a solo canoe and want to catch some crappie. I understand that Gatewood might give me the best opportunity (although it is 2 hours from me).

The campground at Gatewood opens April, 5th. I'm thinking of going up and staying two nights and trying my luck at crappie.

Is this too early? Too late? Decent time?

Any other options in far SW Virginia (I am in Gate City)?

Thanks,
Trevor
