Eagle mountain whites?

Finally got a boat and plan on taking my wife and son out this weekend for some fishing. Question is can I still find the sandbass out in the main lake right now. I know of a few spots on the south end of the lake that my buddy and I have had success at, but wasn't sure if they've moved up into the creeks and rivers yet.

Staged up north waiting for water to warm.
