Location: Wishin I Was Fishin' | I recently saw a show on PBS which stated oxygen is brought into a lake 10 times faster with rain then waves. I'm sure how heavy of rain and amount of wind is a factor, but I can believe the 10 times mark.
This would put a whole new twist on fishing in the rain. Now that I think about it, I have done quiet well on days where it is lightly raining most of the day. However, I don't recall ever catching one during a very heavy rain. |

| Maybe a real hard rain puts so much oxygen in the h2o that it results in a form of hyperventalation, much like that of teenagers breathing heavily into a paper bag at a KISS concert...hard to tell...maybe the sound of the rain pounding the h2o...perhaps additional barometric pressure...who can know hese things? |

Location: Elk River, Minnesota | I would like to see the documentary on that, but you bring up a very interesting thought...I would have to say that my best results under wet conditions are those light steady rains
Come to think about it, the D.O content makes sense (to me) since every little droplet falling is in constant turbulence as it comes down, exposing all parts of the drop to air/oxygen.
Also, when the drop hits the water, it's like an olympic diver in the sense that as the object hits the water, it will pull air down with it. So...more oxygen is being supplied to the water. A steady rain continues the process, whereas a hard driving rain (in some cases) may not last very long.
The other thing about a hard rain (that I feel) is it can have a rapid cooling affect on the surface water, which a major shock in temperature can shut the fish down. Plus, I hate having to drive in a hard rain...hurts the face. And hail?!! oh don't get me started....But a major cooling affect on the water nonetheless.
I think it was Larry Ramsell who wrote an article about this idea, but it was in terms of a stream or river inlet. Larry...any thoughts?

Location: oswego, il | I think it depends on the body of water. I have been told small seepage type ponds rely on rain water for oxygen. Thing is, you look at a wave roll sometime, it turns oxygen into the water big time, has to be better than the rain i would think. |

Location: Wishin I Was Fishin' | My idea is that the surface area of the rain is so huge that the rain drops are probably 100% saturated with oxygen, possibly even super saturated? I am no scientist though.
I can also understand how a heavy rain could cool the water fast.
But what about a warm rain? Would this be an exception and the fish go nuts?
Why is it I have seen the fish go absolutely crazy just before a big front, but only maybe 5% of the time. Most times a huge front comes in nothing happens. What is the trigger for the 5%? The most severe front ever for me was on LOTW and no fish were moving. A big tornado came through about a mile away. Maybe there just weren't fish where we were, but it is a good spot other times. |

| Watching insects, amphibians, birds and mammals can give one a clue to approaching weather systems; systems associated w/ high winds seem to send the creature world scurrying for cover. I have been out and suddenly it gets quiet; birds stop chirping, insects stop buzzing and seem to disappear, and sooner or later here comes a wind related storm. This can occur w/ no bad weather in sight. I'm sure that fish also relate to this type stuff...I'm no scientist either, but learned from an early age that this behavior is common. I'm sure others have been fishing etc. and could actually feel the difference in a weather pattern as it begins to develope, so how much more aware creatures would be to these changes. I guess maybe the old addage of "one must think like the creature he seeks" lends some credence as to what we might ourselves do...maybe....
***Try not watching the weather for a week this spring; you may find yourself observing more closely the systems/patterns as they develope...

Location: Elk River, Minnesota | Joe...
Did that tornado happen two years ago in Early August when all the roads were washed out? I was supposed to head up to Morson the day after all the commotion. Called border crossing and was told no way in past rainy river.
good subject!!
I have also found that the big fronts many times don't have fish moving. Gotta be something to it...

Location: Bagley,MN 56621 | Intersting topic. I have never had much luck before fronts moving in or even fishing during any type of rain, hard or soft, but 3 times this year I popped a fish RIGHT when the rain stopped if I was out in it.
I kept telling myself to stay out there and keep chucking during all that bad weather...nadda......but right when it stopped I got bit. |

Location: Wishin I Was Fishin' | The tornado was in July, we fish out of Nestor Falls. The twister came through Gohere Bay, and you can still see where it came through on shore and on the island. It's about a 100 foot path with no trees. We weathered it over by Deer Bay.
Like I mentioned, I have seen the fish go absolutely nuts before three storms in my thirteen years of hard core musky fishing. Why only these three times? After these storms nothing was moving. |

Location: Hartford, WI | VMS Our group drove through that storm. That SUCKED, I have never seen rain come down that hard. But then again, we got an extra day there, because the road was still shut down. Actually that storm, if memories serves me correct was on the last day of july, and continued into the first day of august.

| Positiv factors for O2 : wind, low temp., high light (photosintezis), high ionisation (thunderstorm).
Negativ factors for O2 : high temp., low light, lower pH (acidic).
Rain and snow can afect pH and it is not allways good sign... Near to industrial areas that is the cause of acidity in lakes and rivers. |

| And one more thing : low presure=low O2 disolved in H2O. Thanx for your time guys ! |
