River Flow/Dam Control??

8 posts in this topic

Hi All,

Just wondering if anyone has information about the river flow from the dam in I-Falls or when they plan on cranking the dam open this spring.

Last year I was up the end of March ice fishing and at some point the dam was cranked open. Sat of the weekend we were there a bomber went through and the resort where we were staying had the front end of a truck go through tearing the V plow completely off the truck.

We were on 4 wheelers and had no idea since there were vehicles all over Sat morning using Adrian's road when we went out, we found out when we got in and were glad we made it in safe.

We are planning another trip late March since we have been doing it for several years and I am trying to find as much info as I can in case we need to drive around to Zipple Bay or Long Point and go out from there.

Thanks

JB

Well they don't really plan to open the dam. They control the flow by looking at the rule curve. Simply put they have a minimum and maximum amount of water that they try to keep in Rainy Lake. So they may have them open when you are up, or all the gates could be closed. No one knows exactly what is going to happen, expecially that far in advance.

Is there a way to get in contact with the entity that controls the dam?? What is the actual name of the dam?

If it is based on water level in Rainy Lake I wouldn't think it would be completely unpredictable since levels shouldn't change drastically over night.

There is a link to the levels on the international falls daily journal website.

The dam is controlled by Boise Cascade in international falls. You'll just have to "go with the flow." There is no way to contact them. They don't know ahead of time when they will open or close the gates. Whatever happens, happens.

You also have to account for the rivers that feed the rainy to. When the ice lets loose from these, increased current and debris also occurs.

Thanks...I will have to check out the link!!

I am just trying to get as much info as I can so we are as safe as we can be. I think we got really lucky we got off the lake safely last year.

I work in the mill and they dont open it up usually till they start getting runoff and the level starts going up. So that will be the only way you can judge it. If your worried about go down by Long Point I have had really good fishing down there in the spring and it wouldnt be affected nearly as much by the dam.

I hope this will help ya some.

Hey Goat,

The Rainy River flow is a very complex equation! The dam is only one factor and even that has a few dozen variables. The rule curve is not carved in stone either. The control board thought they could outguess nature last year and pettitioned the IJC for a variance to hold water outside the curve and then had to release at extremely high flows later to compensate after significant rain.

Temperature, precipitation, and the other streams that Bill mentioned all play into the mix and there is really no way to predict (with any reliabillity) more than a day or 2 ahead what will happen. "The good ones adapt".

Last year looked like a nice easy open but warm weather started a fast thaw and flow that started to muddy things up and shut off the river bite but a cold front froze the river back up really causing problems for a lot of boaters already here. The freeze-up slowed and cleared the river and we had an incredible week of fishing the 2nd week of April.

      First off I am not a waterfowl hunter, so this info is second hand.

      Here in the Morrison/E.Todd cty area, the hunt really seemed slow considering the weather conditions.  Although a few birds were shot early in morning the day seemed slow by most accounts around here.

      Good luck to all.

      No internet in the field today. Had a group sky busting keeping birds out of anyone's range. Riverrat and I got buzzed by teal a few time and a pair of woodies scooted through. Should have had a shoveler and some woodies. The bugs were so bad I lost 4 pints of blood. 

      Now to the fun parts Finn was jumping woodcock son the fields on our way out. Finn did good but does not like no action. After leaving the refuge I checked my dads pond. O yeah there was a woodie sitting on the log bang!! No finn needs to do his job.

    • Lindy came along on our trip to Western MN for duck opener. The guys that came out Thursday to start scouting had a field lined up with alot of geese but they got busted off the roost early in a huge flock and didn't commit. We ended up with only 2 birds today.  She had to stay back in her crate during the hunt but got to play with a wing afterwards.

      what size screen does your new unit have----------------I have a 5 inch helix with side imaging and for me it worthless-------------------the screen is TOO small to see whats going on.  I wouldn't buy any unit that didn't have at least a 7 inch screen.  What unit is your new one??

      I've got a powerdrive also...............my unit would run fine out of water,in water no way.  The prop would barely turn.  I ended up replacing the board the unit and it runs like champ now.  I had it to a dealer and they told me there was nothing wrong with it----------but ,they only bench tested it and did not do a tank test

      Fished Thursday in 30 feet out of the gap and did very well. Couple of slots and a couple of dinks but mostly nice keeper size fish, had to quit early in the day because we had all our fish. Should only get better from here on out I would think.

      Feels like fall this morning!  I was yesterday morning with my son. We did some trolling and it was really good.  I think I might try to get the jigging rods out today and give that a go.  First headed to see the wolves with the kids.
