For example: Lake Bardwell was releasing water and we caught hybrids in the tailrace. Did they come out from Lake Bardwell or did they swim up from Richland Chambers ?

It looks like 20+ miles they swam .. wow.

Could be from both. But I would put money on they swam up river from Chambers with the spawn going on. Though they cannot spawn they still try to do the deed.

same thing at Lake Ray Roberts Dam - fish swim up from Lewisville.

I just hope they keep releasing and the hybrids stay up there until Friday .. I am hooked now . hard to go back to sandbass .. and hoping for a "GOOD FRIDAY" of fishing.

I agree with Danny, releasing water will pull fish out of the lake. They will also be swimming up stream to spawn or in Hybrids case the urge to spawn. Even after the spawn is over in the middle of the summer or fall if water is being released, below the dam is a great area to catch fish.

large fish will not make it thru generator turbines in 1 piece.
there are "screens" covering the intakes w/ 4-5" mesh to prevent it. Smaller fish(4-12") that have been "pulled thru" are easily identified as they float downstream, usually always small drums or crappies.
that said, if the flood gates are open, or the spillway is
running, larger fish from the lake will be in the tailrace.
The fish you are catching are either RC fish or resident river fish. the same thing happens @ California Crossing, sandy lake rd, LLELA, etc. when the water runs good.

I would think that sometimes the fish at the spillway are swimming upstream while others have passed through the gates. There is no big lake beneath Livingston, but they catch them beneath the spillway. I think I've heard of reports of stripers now showing up in Trinity Bay as well, all courtesy of Livingston. Just my guess.

same thing at lake buchannon, I do not believe the lake below is stocked with stripers/hybrids but they are there. Interesting more big stripers come from the lake below that dam. Agree they get sucked out through the flood gates.

EAgle Mountain has never been stocked w/ hybrids but are occasionally caught....leading me to believe they were spit out of Bridgeport.

Contrarily, some Hybrids can breed. 3/4 crosses are not altogether uncommon.
Areas where oxygen is rich are almost always good places to fish and often the fish there are much more aggressive than you might find elsewhere.
Some fish do get spilled over and some die but some do survive.

I remember reading about a tagged striper caught at the Galveston jetties that had been originally tagged in Toledo Bend, so it must have gone over the dam and downstream.

Started looking after posting .. here is the link:

I know very little about reservoirs but am pretty familiar with ponds. In the event of a big rain, 99% of the fish will try to go "upstream". Some smaller ones can and will be sucked out of an overflow but it is rare to see a larger one go over the spillway. The only exception is grass carp.

This maybe true, but it seems stripers in particular move away from muddy water which is towards the dam. Who knows.

Scout, it may surprise you to know that striped bass were apparently native to the Galveston Bay system. I remember reading about a commercial striped bass fishery there back in the twenties, which I believe was before they began stocking them in freshwater. They were fished out of existance.
