John theere is a big difference between and extra 5-10 inches and 40ft.
Rick thank you for bringing your knowledge to this board. Your info is extremely informative to me. The invert community would greatly expand with the amount of gravel covered thus providing overtly more food for the food chain. Ie: more crayfish,sculpin,and minnows that the larger fish as well as the smaller fish can feed on. HHMMMMmmmmm kind of like a geometric progression of the food chain eh Rick? Inverted!!???
Is my thinking right on this Rick? Can do nothing but good for the fish and the benthic. (did I use this term correctly)?
John I doubt an extra 10 inches of water will allow boat traffic to navigate up through the state park as most of that water flows through the gravel as opposed to over it. Tried to navigate down it on saturday and the main channel to get up and down it has changed considerably. Impossible to go down without getting out and pushing a boat. Did not used to be that way. I figure that an ex-tra 10 inches of water would only actually cover 4 or5 inches of water over the gravel and it would take a channel of at least 10 inches to navigate up to the C&R area so I figure you are safe from the hordes of bait fishers and boaters. Jet boats would be a different story. (more on motors and size limits at another time)
Dano and X-tra 10 inches of water year-round would move the fish in different ways. It would only confuse the fisherman for a short period of time. it would not take you long to figure it out. It would however cover a little more gravel and allow for more spawning area over existing areas trout use to spawn in. In a lot of areas you would not have to walk as far to get to the fish.
Rick...Your Lumnology explanation I think I got.
It explains why the water flow from the dam is actually warmer at this time of year and probably explains a good bit of why a shad kill happens. (especially in the winter) We are still a little confused as to why we get a minor one in the late summer. Perhaps you have more info on this one as well?
My question Rick is when fisherman talk about a lake turning over how does that actually happen.. I do notice that there is an event on the river Ie: the water in the river takes on a STAINED look to it. During generation it is much more evident. The clairty appears like a weak version of hot tea. This seems to happen every year and this year happened during the later days of nov and through december.... There has to be some physics involved here in a big way. Tannin perhaps? Ie: leaves staining the water or does the metalimnion hold such particles and gravity and heat take such particles towards the bottom. As you can see; am searching for an answer on this one.
Thanks Rick.
