Yep, bird legs. My wife had a biologist at seaworld, zoo, or some place like that confirm the theory several years ago on a field trip with one of her classes.
I might sound silly but this is what I've been told.
I've never researched it so I guess you can call me correct or gullible* lol
Water gets evaporated with fertilized fish eggs into the clouds.
It rains in ponds and tanks and such and the eggs hatch later.
Sounds plausible,,, that's why I've never really questioned it.
I also heard that's where Sun Perch got there name....
Don't know about that one either....
One more vote for birds. Heron regurgitate what they have previously eaten on the water to attract more fish. This could contain eggs or even small fish.
Ive always been convinced that if you dug a whole filled it with water and came back a week later there would be perch in it. Like the grew out of the dirt or something. But the othe posts make much more sense.
This was once believed to be the case. It was known as "Spontaneous Generation" or the origin of life from inanimate matter. Maggots appeared to "spontaneously generate" from raw meat. People actually believed they came from the meat (or spontaneously from dirt) until someone (I think I remember it was Pasteur) proved it to be wrong.
I did some graduate work in Marine and Aquatic Biology where we seine netted fish from many rain pools on Mustang Island (in the early '70s). The rain pools we seined fish from are temporary collections of rain water in the sand dunes. They are only depressions in the dunes that collect and accumulate rain water. They may or may not dry up depending on the amount and frequency of rain. There is no connection with the ocean or other permanent (or even temporary) water source.
We netted fish out of every one of them. The fish got there because birds sometimes drop them. The birds would catch them somewhere else and drop them accidentally when flying over a pool.
That's the same thing that happened to populate the drilled quarry holes on the original poster's property.
i had a friend who's grandkids fish (and caught) catfish i a neglected swimming pool. neglected for several years.
i believe in the eggs sticking to birds but turtles are puzzling. maybe some of the birds are farmers and stock the turtles on purpose?

After a volcanic eruption and the cooling process, the crater fills with water. And at some undetermined time, someone discovers this new lake. And finds it has fish in it. How did they get there?
I looked for recorded examples and found out that after the eruption of Mt. St. Helen's volcano, the lake below was filled by the avalanche of debris. There is no way any fish could have survived the eruption or the period afterwards when the lake was depleted of oxygen by bacteria. But fish were later found here. It's likely that fish could have survived in the ice covered waters near to the lake and were washed down into the lake to re-colonize it with fish. Perhaps this is how fish end up in volcanic lakes - they are washed in from another area of water. If the lake is fed by a stream then this could be an explanation, but where rain appears to be the only source of water, it is harder to explain. It is also a possibility that the lakes are illegally stocked with fish by keen fishers, although this is unlikely. Who wants to climb a volcano just for a spot of fishing?
A more interesting explanation could be that twisters or whirlwinds pick up fish from one lake and carry them to another. This may seem a little far fetched but there are plenty of examples of where it has literally rained fish. Obviously it would have to be a pretty strong whirlwind to carry a fully grown salmon-sized fish (it would really hurt if one of these dropped out of the sky onto you!) but smaller fish are more easily picked up by the wind. During thunderstorms small whirlwinds and mini-tornados are formed easily and when they move across water they pick up small debris such as fish, fish roe and frogs. The little creatures can be carried for miles before the clouds open and rain brings them back to Earth.
Another method of transportation could be via birds. After a picking up a tasty snack in a lake, Mr Bird proudly carries it home to show his kids but unfortunately is caught in a freak gust of wind and the slippery fishy manages to wriggle out of his beak and falls to Earth to populate a previously uninhabited lake. Or maybe the birds spread the fish roe between lakes. Lets see what Charles Darwin has to say on the matter in his 'Origin of the Species':
"When ducks suddenly emerge from a pond covered with duck-weed, I have twice seen these little plants adhering to their backs; and it has happened to me, in removing a little duck-weed from one aquarium to another, that I have unintentionally stocked the one with fresh-water shells from the other. But another agency is perhaps more effectual: I suspended the feet of a duck in an aquarium, where many ova of fresh-water shells were hatching; and I found that numbers of the extremely minute and just-hatched shells crawled on the feet, and clung to them so firmly that when taken out of the water they could not be jarred off, though at a somewhat more advanced age they would voluntarily drop off. These just-hatched mollusks, though aquatic in their nature, survived on the duck's feet, in damp air, from twelve to twenty hours; and in this length of time a duck or heron might fly at least six or seven hundred miles, and if blown across the sea to an oceanic island, or to any other distant point, would be sure to alight on a pool or rivulet."
So fish's eggs could potentially get stuck to birds who have recently visited one lake and be deposited in the next. Well traveled little fish!

This, the vast amount of ducks that fly all over the world with fish roe in/under their feathers and the vegetation (with the eggs) in their waste.
This is the same way aquatic weeds and plants make it to a distant pond.
