| On occassion when fishing a northern mn. lake I have snagged and broke off chunks of mineral matter that looks like corral.My son took a chunk to school for his bio teacher to look at. He thought maybe it could be some old cement. Problem with that is I've hooked this stuff in other locations in the lake. The lake does have many springs in it and at one time there was intrest in mining copper in it. I also heard from one of the locals that somebody was taking core samples from the area this summer. Anybody have any idea ? Corral, mineral deposits, theres even a old rumor about a metor. |

Location: Antioch, IL | No such thing as freshwater coral. It could be fossilized "saltwater" coral. There are many "Dead reefs" throughout lakes in the midwest and North. Millions of years ago this was all ocean. Could also be mineral deposit/remnants of some sort, maybe even some form of bacteria. Hard to say without seeing it. |

Location: Hayward WI | Could possibly be marl deposits:
If the amount of carbonate (CO3--) is high enough, it will react with calcium in the water to form CaCO3 (marl). Marl precipitates out, leaving a white substance in the sediment-sometimes even producing elaborate underwater formations. Marl can often be observed as a white precipitate on plant leaves in hard water lakes. Plants speed up marl deposition by using carbon dioxide (CO2), which raises the pH and converts most alkalinity to the carbonate (CO3--) form. By precipitating phosphorus, marl formations help control algae growth in marl lakes.

| I'll have to dig it out of the snow to take a picture of it and post it . I do know people have lost anchors in it. I've even stumbled across one formation thats about 8' round and 15' tall in 22' of water I marked it on my Gps I'll have to take the aqua view up there this winter. The waters too green any other time of year. PS its not a space peanut either

| I thought I saw this once but it turned out that it was nothing more than a reef of old bicycles. A couple of schwins, a murray, and a huffy with a banana seat. |

Location: Minnesota | According to the MN DNR website there are about 10 MN lakes that have a variety of freshwater coral. I personally have seen it in Eagle Lake, south of Battle Lake, MN. So it is possible that it is you found a reef. I would check the DNR site as they have the complete list of lakes with freshwater coral.

Location: Antioch, IL | Could you please post a link to this list. I cannot locate this on the MN DNR website. From my knowledge (and I don't claim to know a whole lot about much, but I am a passionate aquarist for 25+ years and a wholesale importer of live coral and fish) there are no real live freshwater coral. There are Dead reef (Fossils), algea and bacterias that are similar and can resemble coral, and various mineral deposits. I think erico probably has the answer. (sorry, not sure if I'm taking this thread in the right direction for this site, just interested in the topic)

| It took awhile but I found it. Ofcourse it was under 12" of snow. I'll try to post pictures tomorrow. |

Location: Minnesota | Fish and Whistle -- You are correct -- that it is a fossilized coral reef -- sorry to mislead.... |

Location: Stevens Point | I would agree with erico as well, that is if it isn't fossilized coral reef. There are a few of these marl lakes in central wisconsin which would be capable of steeling anchors, I would imagine it could happen in MN as well. |

| eagle lake in mn has live freshwater coral that jaque cousteau wanted to do an investigative report about.......the home owners ass. blocked him because they feared the publicity would ruin the lake |

| I think I know what you are talking about. I think I've had one certain chunck of this stuff in my boat 3 or 4 times over the last few years. My wife keeps asking me why I throw it back in the same shallow spot. I tell her its so I can catch it again of course. |

Location: Pelican Rapids, MN | We have a few select lakes in western MN with verified fresh water coral. It does exist - Not plentiful here, but it does exist. |

| Sorry Virginia,
Although there is of course a Santa Claus, there is NO freshwater coral.
On the other hand, there are a LOT of strange things in MN that HAVE BEEN VERIFIED... |

| Sorry for dropping the corral on this topic .I did talk to the DNR about this , they tend to believe its formed from minerals getting pumped up from the many springs on the lake . They also said theres no such thing as fresh water corral. But if there are known lakes with such a thing then maybe this guy was just giving me a convenent answer trying to protect a fragial resource .I'll take a chunk of it to the DNR building and see what they say . |

| Onieda Lake in NY has what they call 'Pankcakes' I think. If I remember right, they are nodules of magnesium and something else. If we believe the idiot Al Gore (who has cost tax payers billions with his scheme) then we will have coral in all the lakes because of rising temperatures and rising seas!!!!!!!!! Look out!!!!! Ahhhhh!!!!!! |

Location: Pelican Rapids, MN | They have called it fresh water coral for as long as I can remember - Maybe it's just an easy name sake - But a stationary growing organism on the bottom housing other living organisms sounds like coral to me! |

Couldn't you also call those 'weeds'?  |

Location: Bemidji, MN | I think erico got it right with the marl. It is very common in hard water areas. My neighbor has a boat (on plantagenet) that sits at the dock every year and hardly ever gets used. You would swear it is encrusted in coral. Also before they tore down the old aquatics lab at Bemidji State University, Doc Cloutman had a nice collection of rods and things that were rescued from the bottom of lake Bemidji that were encrusted in marl. I could see where if a lake had really hard water, it would be all over the bottom. When I pulled my dock out this year, I had to scrape it off the legs to get them to slide up. It can form pretty fast if the conditions are right. |

how deep of water was this in sam? i don't have footage like you do of this but i remember about 6-7 years ago finding 5 cribs in about 15 feet of water on upper eau claire lake in barnes, wi. with my aqua view that looked identical to this one. lots of windows in it like this one. i remember seeing strange looking formations growing all over the sides of them as well. loaded with fish too. smallies, muskies, walleyes etc.

| That doesnt really look like a fish crib looks more like metal, are you meaning a water crib for sucking water? Cause that looks cool as heck imo.
Sorry off topic. |

| there are only two lakes in the world that have fresh water corral and you are chipping it away if you ever got caught by the DNR your looking a a real fine! |

| I took the chunk I have to the DNR today, the lady was fascinated by it and said it appears to be formed by an under water spring bringing limestone deposits and other minerals to the top to form what looks like corral but isn't. The rock isn't that old less then 100 yrs is what she guessed. |
