What we've been observing is that the fish are definitely moving in with the tide (rocket science), and head to any depth on the flats between 10 and 2 to 3 feet. The smallest juvenile flounder are even in the 6 inch to 1 foot deep water. All of the flounder, no matter what age, are not like the gulf flounder of which I've found the most abundant information on the internet. Gulf flounder apparently don't spook and are highly aggressive, but are in deeper (20 ft?) water with murkier conditions. Anyway, what I know of our fish is that they are ghost spooky. The idea of the shadow of the boat crossing their back spooks them. We had first started fishing heavy sink tips but decided that with how shallow the water was, the sink trip dragging across the bottom was probably spooking the fish. We set up in a drift with the tide or the wind (whichever was in our favor), so that we would float back toward the ocean while doing a slow strip or even just a troll almost to cover a large area of water. We actually saw about 20 flounder all together, but obviously didn't have the right presentation. To confess, this was my birthday float, so we enjoyed a bottle of wine from the SILs and pretty much blanket casted our hearts out.
We did see quite a few of these sand lances doing what later research said was a spawning activity. It was definitely cool to see these huge balls of sand lance and the flounder were always right in the vicinity. New flies will be tied.
This photo was taken from the interwebs. I didn't have the means to capture a sand lance at the time.
So again, no flounder to the boat, but I feel like we learned a lot. We learned a lot just in time for some supremely shitty weather, so now I sit searching google for flounder instead of searching the estuary. Soon. On that note, here is my favorite picture found today of the starry eyed flounder. The California Department of Fish and Game has a true artist on their hands...
Yeah, I'm a smart ass, but c'mon. On a cooler note, we dredged the internet for this video today and got some insight into what it actually looks like when a flounder is interested in what you're waggling in his face. When the weather clears, we're going to try this in a more fly fishy kind of way. Rad.
