Some kind of mill?

  1. montana lover says:

    could it be a fish ladder?

    • Sue in NY says:

      Yeah, that’s my guess … a fish ladder … our salmon get them here in NY for when water is high. Though the depth of the ladder and low slope kinda make me wonder if it is one. Go HOBOPLANET !!!

  2. Andrew in VT says:

    Or possibly a weir for measuring flood flows?

  3. Okay you Montanans–what is this??

  4. A Fellow Traveler says:

    As a crazed engineer, I’m going to speculate. This is a guess. This is only a guess. Please stand by.

    It looks like it is in a dry stream bed. I’m going to guess that the stream, when it flows, has some chemical problem (perhaps acid rain?). The wheel turns some kind of auger in the narrow portion, where lime or some other chemical treatment is dispensed.

    You will now be returned to your regularly scheduled programming.

  5. Jeff says:

    dry yes….monitor of flood waters maybe…could signal down stream so others are prepaired and not flash flooded. I thought fish latter at first thought too..

  6. Don in Tennessee says:

    I give up. What is it? I thought maybe some type of monitor for flood waters but not sure.

  7. MN Roxanne says:

    it’s something interesting enough to get a picture! so we wonder….

  8. Oh where oh where are our little Montanans, oh where oh where could they be? With their information and their goody tidbits oh where oh where could they be.

  9. Candice in Alabama says:

    Hmmmm……Haven’t a clue!

  10. Michelle says:

    What an extremely odd find!

    I’d guess it helps control stream flow for spring run-off. I don’t see any type of system for sending data, so I’m guessing it’s not for monitoring. Was there a small tower nearby at all though?

    It’s just so…odd!

  11. Local Montana Boy says:

    This is a fish trap. It keeps the unwanted fish from migrating upstream. The gates can be raised or lowered depending on water flow rates. The Jocko has a trout fish hatchery.

  12. John says:

    Yeah, my first guess was a fish trap. They used to use them a lot on the Columbia River years ago. This looks a lot smaller than those use on the Columbia, but the idea is the same.

  13. Michelle says:

    But why is it in a dry creek bed?

    • Local Montana Boy says:

      The upper lakes and creeks depend almost entirely on snow to keep them flowing and cold enough for fish to survive. By mid summer, and especially in a drought year, most are either dry or very tiny. This past winter was very poor for the amount of snow in the high country. Demand for irrigation water downstream (mostly for irrigating hay – for horses and cows) means that any remaining in the upper lakes gets released to satisfy these demands.

      Water rights laws in the west are some of the most ancient, confusing and backwards laws in existence. Its called “First in time, first in line”.

  14. The Lock says:

    It’s part of a fish farm.
