I'll jump in here and try to help with what I know. I saw on fishin.com somewhere a post that showed a link to the IDNR tracking study for lake Monroe.

You might do a quick search on fishin.com for "Monroe" or "Stripers" and see what you can find. It may have been in the Kentucky fishin.com forum.

I don't fish for hybrid stripers so I can't really give you any information.

I do know this. They won't be below the thermocline as there is not much dissolved oxygen below the thermocline at this time of the year.

I looked at the DO levels for Patoka Lake and below 15 ft the was very little dissolved oxygen. Not sure what the DO profile is for lake Monroe.
