  1. I have seen one pond where trout did reproduce, with no stream feeding it, but the springs in the pond (1/2 acre) produced enough water to keep a three-inch overflow pipe full year around. I wish I had springs like that!

    1. Thanks for the comment, reliable springs are basically just an underground stream entering the pond. They certainly do a lot to improve the water quality. All trout ponds benefit from them.

  2. When I started reading this, it sounded exactly like my situation. I had a 15 acre foot pond on my small ranch SE of Denver. I stocked it with 400 pounds of rainbows in early spring. It was spring fed with aeration. Unfortunately, the aeriater broke down and all the fish died by late summer due to excessive heat and a deadly duckweed bloom that covered the pond.

    1. Sorry about the loss of your rainbows. My feelings are mixed about duckweed. It can be a two edged sword. Yes, it smothers the surface and reduces oxygen level at night. But by covering the surface it does shade the entire pond, which should assist in insulating it against surface temperature. It also blocks so much sunlight, that it prevents algae from blooming.

      Although once it dies, and starts to decompose that will cause the oxygen levels to plummet.

      I feel in ponds where the water temperature is borderline keeping trout alive over summer is always going to be a battle.

    2. I have seen only one very small pond in the wild that supports larger than average brook trout. It’s near a stream in thick woods under a tree canopy. There is no inlet or outlet and the water level remains the same all year. I don’t see any bubbling spring and there is no seaweed of any kind. The bottom is mud. My guess is there is a constant low flow underground spring. Perhaps a deep well with a temperature sensor to add more water when temperatures rise with a pond overflow might copy the natural pond, that and heavy shading with trees such as elderberry as I have seen at another consistent brown trout hole.

    3. Sorry to hear that Tim. I fish a 6 acre pond unfortunately the owner allows sewage from his restaurant in to the water and I don’t think it the water any good or the fish

      1. Eventually, it will cause nutrient levels to raise, increasing the risk of algae bloom. Certainly not good for the long term health of the pond.

        That reminds me, my father use to tell a story. When he was a boy, the best fishing in town was always at the discharge pipes from the slaughterhouse. It was basically a constant feeding frenzy, but that was in a medium size river with steady flow, so could handle abuse somewhat better than any pond.

  3. Don’t do it their natural environment is running water if brown trout. They being in streams and rivers. Rainbow yes but I wouldn’t advise it. It there are any other fish the trout will eat them if you have koya car they will eat their fins. I have seen it before so I wouldn’t bother. They will always look for running water so don’t be surprised if you find one on the ground as they will jump out looking for running water it’s their instinct.

    1. Thanks for the comment, trout are both predators and prey so there will be friction when living with other fish.

      Brown trout are just at home in stillwater as they are in running water. Back in their native Europe, brown trout (Salmo trutta) come in three main morphs (or forms). These are the river-dwelling Fario, the lake-dwelling lacustris, and the anadromous or sea run trutta.

      The first brown trout brought into America (The von Behr brown trout) were from eggs sourced from trout living both in mountain streams (fario) and large lakes (Lacustris) in the black forest area of Germany. A couple of years later in 1885 trout eggs from Loch Leven, Scotland (trutta) also arrived in New York. In the hatchery, trout from all three sources were interbreed. So the generic american brown trout of today is likely a hybrid of all three forms. So they have traits of river living, lake living and anadromous. Although, very few brown trout become searun in the states.

      Since then, more genetically pure strains of brown trout have also been introduced.

      In saying that, all three forms seem capable of adapting to live in all three lifestyles if conditions change. For example, the river living fario can easily adapt to living in a lake if their stream is dammed, and the sea run morpa trutta will take up resident in a stream if they can not reach the sea or if food is plentiful.

  4. I live in Washington state and have seen some impressive man made trout ponds. The most productive have a creek that flows in and an overflow culvert for the outflow. The creek flows all year around which will cool the pond. Some people just plant them with tripods they buy, but the eagles get a lot of them. Other people just stock them with fish they catch near by, rainbows and cutthroats. You just cant have a stagnate pond for trout. Cool water with oxygen is a must. Do your research, and do it right. Its worth the it

    1. Well said, thanks for the comment. Hatchery fish do quickly fall victims to predatory birds it seems. Other times they all swim down the outflow and take up residence in the outlet stream.

  5. No they will eat anything else that swims there they need flowing clean water it’s their habitat as far as brown wild trout go, rainbow trout could for a while but not for long they have the same mindfulness if wild brownies but there not really a fish that grows wild more for stocking trout farms for fly fishermen,
    This is the case in the UK anyway.
