Welcome to bass fishing. We all had to start somewhere and today you have the internet to help you with answers to your questions, This site for example has feature articals for the new bass fisherman to read.
You apparently live in Eastern Penn and fishing river and small lakes, to very different environments for bass.
During the warm summer period months, getting out early was a real advantage because the baitfish and crawdads are active close to shore, near or in cover. As the sun comes up both baitfish and crawdads go deeper and become less active.
During the colder water periods of late fall and winter, the baitfish school up and the crawdads stay in deeper water. There isn't a lot of prey for the bass near the shoreline or in cover, so the bass move deeper to be near their food sources.
Bass are cold blooded, meaning their body temperature is the same as the water and the bass slow down and eat less when the water is cold. The bass become less active and will become active for only a short time period, about every 3 to 4 hours.
The short cuts to learning to bass fish is to ask the successful bass fisherman in your area what they are using and how deep they are fishing to catch bass. If you are polite, most fisherman will be very helpful. Don't ask where they catch their fish, few fisherman will tell you about specific locations.
Don't try to learn more than 2 presentations at any one time. The best to start with IMO are; soft plastic worms, use the split shot or slip shot technique and drop shpt with small 5" to 6" finesse worms. Stay with the basic colors; night crawler browns and green with red flake. You can drift these rigs slowly on the bottom, around points on the main lake or anchor and let the current slowly move the rig along the bottom in the river around bridges and deeper holes.
The second lure to use is a crankbait, the lure with the deep diving bill.
Agian I would suggest 2 lures; a Bomber model 7A, that will run about 8 to 10 feet deep and a 200 series Bandit that runs about 6 to 8 feet deep. Colors; fire tiger and crawdad brown.
With your small boat and motor, I suggest you to learn to fish a crankbait by trolling. The speed you troll should be the speed the lure is swimming with the best action, so let a few yards of line out and look at the lure along side your boat, a slow walking speed or 2 mph is about right. Cast the lure about 50 to 75 feet behind the boat and try to stay in about 10 to 12 feet depth, the lure should bump the bottom once in awhile, but not a lot. When you see shallow water ahead, or the lure is bumping the bottom too often, move out to deeper water so the lure doesn't snag, then move back to the 10 to 12 foot depth. make lazy S turns about 10 feet to one side, then back agian about every 100 feet or so the change the lures speed. This will teach you what bass strikes feel like and where the bass are located. Once you catch a few, then go back and try casting the crankbaits and also try the soft plastic worms in the same area.
You may also want to make or buy a lure knocker to retrieve crnakbaits that have snagged into the bottom or whatever.
Stay with these two presentations until you are consistanly catching bass.
These 2 presentations should keep you busy until the spring, then add spinnerbaits and buzzers to you presentations and fish the weed/grass beds, early and late, continue with the soft plastic and crankbaits during the mid day hours. Good luck.
