I know very little about the waters I fish. I know nothing about brackish water. We all fish different waters.
As I said earlier last Winter I was faced with cold muddy water, combined with higher than normal lake levels. I "thought" I needed to go up the creeks, and up one river to find "better" water. I didn't find bass there, but found the few I found in deeper water on the main lake. When people talk I try to be a sponge, and learn all I can. A conversation I had months after the muddy, high water made sense to me.
OK, more information about the body of water I'm talking about. Lake Wylie, in NC/SC. It's fed by the Catawba river, out of Mountain Island Lake. It's also fed by several creeks and the South Fork River. I've read that 1/3 of the water coming into Wylie comes from the South Fork. Wylie is ~13000 acres, and close to 30 miles long. I have read that on average it takes "water" 30 days to get from the Mountain Island dam to the Lake Wylie dam.
OK, back to the conversation I had with a retired BassMaster pro several months after struggling with the muddy high water. I told him I had zero luck up the creeks and up the South Fork river. He said when the creeks and river flooded they took in a bunch of trash, and even stagnated water from pools/puddles near them. He said this would drop oxygen levels causing the fish to flee. (or trigger a fish kill if bad enough). I didn't see fish floating so I don't think there was a major fish kill. I thought the newly flooded areas, and the areas near them would be rich with "new" nutrients.........instead of deprived of Oxygen.
Right now it doesn't look like I'll be fishing flooded waters anytime soon. The power company usually keeps lake levels within a foot of so. Right now the lake is down a good 4 feet. That's not much compared to many lakes, but I suspect it's a shock for bass here. This time of year, with water temps in the low 60's I'd expect to find a bunch of bass, and baitfish up the creeks. I'm only seeing a few baitfish, a few Gar, some Carp and some small (10 inch) Spotted bass. 2 months ago I was catching decent LM's and Spots up the creeks and catching 10 inch Spots on the main lake. Maybe I'm giving the Bass too much credit, but I believe the mature Bass recognized the lowering water levels and went to deeper water in the main channel. (that's where I'm catching them) There's way more bait fish in the main lake also. I also suspect the juvenile bass are following their instincts and going up the creeks because the days have gotten shorter.
I can't find any hint of a thermocline, but the lake it too clear (and too warm IMHO) to be experiencing a normal turnover.
So now I've brought clearer than normal water into a muddy water thread. In warmer muddy water I have really good luck in the mouths of the creeks using flashy lures right up in the middle of heavy cover.
