My apologies for not responding sooner... I'd be happy to share some insight...
Beltzville can definitely be a challenge and more times than not, lives up to its reputation as "The Dead Sea." That being said, I've also had great days there. I like fishing the dam, a few select coves, up the no wake zone and finding structure along the shoreline of the main lake. The power line stretch is very popular and shallow. There's also some nice stumps across from the Pine Run launch, Personally, I haven't done great at either spot.
Over the past three years, I've been most successful with a dropshot. Have done decent on cranks and jerkbaits in the Spring. My buddy likes to throw Texas-rigged Paca Craws and has done well with a Bama Rig too. We both started getting into Jigs last year and both caught a few... this will be my primary focus this year.
I hope this helps. Let me know if there's anything else you'd like to know.
I'm still holding out hope that it'll be open by Friday, though that seems to a little too optimistic at this point.
