Centennial is butt, imo. It’s really pressured and crowded, so I wouldn’t bother unless you know some top secret Japanese techniques to fool them. All the lakes in that area are pressured, but Kittamaqundi isn’t too bad; you just need to know how to approach it. Texas rigs and toads will get that job done. Fish Florida for a minute, and Kittamaqundi becomes light work. Granted, I haven’t fished there in a while, but it seems the lake hasn’t changed much.
 
The big three reservoirs are nice if you’re on the bank. Not too experienced with loch raven, but it’s not a bad place at all. You can rent a boat if you need, but launching your own will be difficult because of the regs. Liberty Reservoir is great for bank fishing. There’s trails to take you all over, so long as you’re fine with hiking, and maybe some bushwhacking. The major parking lots can be crowded on weekends, although you can usually walk away from most people. Generally, people don’t walk more than a mile from their put-in point. Regarding the actual fishing, Liberty is wood-oriented. There is some SAV that comes up, but it’s strategically negligible, imo. Loch Raven is more of a grass fishery, but not nearly to the same extent as Kittamaqundi, for instance. Fishing over the grassbeds can be solid, but there’s also wood to fall back on. I have very limited experience with Prettyboy, but iirc it’s similar to Loch Raven, only with a stronger smallmouth population. All three of the main reservoirs are largemouth dominant, however. Piney Run Reservoir is starkly different than the big three. It’s mostly pads, and everyone frogs. If you can flip and punch, you’ll be ahead of the rest. Piney run has an entrance fee and is moderately pressured.
 
Rocky Gorge, Clopper Lake, Lake Elkhorn, Wilde Lake, and Tridelphia are close to Columbia, but I haven’t fished them.
 
On the smallmouth front, the piedmont isn’t that great. The obvious choice for central MD smallies is the Patapsco. Great for numbers, iffy for size. It can get crowded, so be mindful of that. It’s worth the drive to head west for brown fish. The Potomac and all of its tributaries are solid. The Conococheague is good for numbers, with some big ones in the mix. The Monocacy wasn’t good to me in the past, but I hear it’s rebounded significantly; I’ll need to check it out. The main Potomac, especially the lower section, is where you go to target big smallmouth, at least I’ve heard. The Susquehanna is the Potomac’s eastern counterpart. The shad run is over, but you should be able to find plenty of other species to mess with over there. Flatheads, rockfish, snakehead, eels, suckers, and of course the smallmouth. The Susquehanna is touted as being one the of best smallmouth fisheries east of the Appalachians. I don’t have enough experience there to verify that verdict. I will say that wading the Susquehanna with  swim shorts and a pair of old sneakers will probably be difficult. The western rivers are kinder to that sort of fishing. 
 
While you’re in God’s Country, you should check out some of our other offerings, such as snakehead, rockfish, and brook trout. Aside from that, that’s about all I have to offer. If you have any questions, I’ll try to answer them. I’m honestly not that experienced fishing the area, or fishing in general. There are people on this forum that have been getting ‘er done in MD since before I was in diapers, so take their advice over mine. Above all, explore and figure stuff out for yourself. There are opportunities in central Maryland as long as you look for them. Good luck
