Good tutorial on hybrid fishing LC on Youtube. Search "Lake Conroe Hybrid Fishing" and watch Barry Stokes fish with a local guide in 2019.
I hosted that show with Barry Stokes. It was a great time and we smashed the hybrids!
Yes there are still good numbers of hybrids in Lake Conroe and May is a great month to catch them. I do expect a steep decline in big fish numbers 2021 and 2022 due to two years of missed stockings. They were stocked last year and apparently this year as well, so that's good news.
Lake Livingston is our primary lake, but we fish Conroe a lot in the winter and early spring when Livingston gets muddy. Lake Conroe gets extremely crowded with pleasure boaters once the weather gets nice.
We don't troll but it can be very effective. If that's how you wish to fish I'd recommend a deep diving 6XD crankbait for 20' or less and some sort of diver for any water deeper than that. There is a nice structure called the dump on the south end of the lake and a nice ridge line just south of the bridge mid lake that hold hybrids this time of year. I'd recommend trolling those edges.
There is a nice class of 22" hybrids in the lake right now.
