Better to get butter by planting grass along the edge.
Usually ponds are oriented to minimize waves from prevailing wind, this also helps.
I sometimes ride in a brackish lagoon that at lower tides in summer is 12 inches or less in large areas and full of weed.
Great butter spot in most conditions, but in those conditions, it sucks.
Lines can get full of weed, face full of slimy weed, etc.
Also it has a muddy bottom, that also is not nice when shallow.
Nothing like lines full of floating vegetation and mud up to your knees.
With fresh water, some from runoff, and shallow depth, there is also a concern with what kind of micro-organisms will thrive in it in summer heat. Some of them will thrive in your sinuses, ears, GI system etc.
