Keep a good notebook. While I fished the stock ponds of South Dakota for Largemouth Bass, I would cover a lot of water unsuccessfully, using a fan pattern (9:00 to 3:00) casting from the bank. After putting on my waders, I would wade out, and cast parallel (even towards) to the bank, and double my success.
Of course, this was back in the '70s, Largemouth Bass, small tanks (5 to 10 areas, & not deep), and the bass were small.
Find some shallow rocky areas and cast parallel to shore. Bang the crankbait all over the rocks and beat up the front bill. Baitfish colored. Smallmouth love that technique on the Willamette. Good way to cover water and find where fish are. You will get bites and some occasional snags.
