Like said above alcova is wide open. If it stays cold for the next week it still would only have skim ice.
I'm not sure if pathfinder still has ice but I will look and see if I can find anything.
Goldeneye outside of Casper has good ice still. It's like elevenmile but smaller.
If you could bring the spinning gear or fly gear you should fish the spillways. Alcova, kortez and grey reef.
Near thermop is Boysen and it's spillways. Im pretty sure the ice on Boysen will be fine. The spillway of good fishing also.
Check out Bass lake Also.
Fremont lake has not frozen solid yet this year and may not.
But Pinedale WY is a great town. Check out some of the finger lakes around.
The lakes in and around the national parks are all frozen with good ice.
Keep checking the weather and road conditions.
