Does Common Sense Play A Part In The Nechako Flood

I don’t like going down to the scene of the flooding on the Nechako River because I get annoyed as hell and frustrated and then I realize there is little point in getting my blood boiling when nothing gets done.

Case in point, just how many times have we sent a back hoe down to take the logs out from under the foot bridge that has been straddling the stream that is trying to cut a new channel around the ice jam on the river?

I have been in attendance at two occasions, but I am told there are more. Now I know this may be a novel approach, but did someone, perhaps even an engineer or an ice expert suggest that maybe we should pull the bridge out of the channel so we can allow the water to flow by unrestricted, or is it better to run up the tab for the equipment by having them appear every few days to dredge it out once more? Now it might take a few minutes for a D-8 to pull the bridge out (which is now battered to hell from the logs and is becoming of less and less value) but then there must be brains smarter than I who have determined that it should remain in place, sort of a make work project.

Now I return to an item that I tried to convince the city to move on, with I might add, little to no response.  That is the matter of opening up that side channel that exists around the ice jam and making it large enough to accommodate the flow of the river so as to prevent the increase in flooding. It might cost 5 or even 10 thousand to do the job , but when you look around at the million and a half we have spent so far, it doesn't seem like a high price to pay. I really don’t care if it even stops 10% of the flow from heading into people’s yards or the businesses along River Road, that is a good investment. By the way don’t throw the Department Of Federal Fisheries as being the hitch into the matter, the city knows that is not an issue.

When you were a kid you often built little dams as the spring melt took place. What did you do when you wanted the water to escape?  Well you cut a little channel around your dam and whamo out went the water.

Pretty basic stuff, instead we seem content to build our dikes higher and higher instead of trying to find a way for the water to pass around the ice jam.

The diversion around the jam is easy to construct, it doesn’t get rid of the ice jam which is now far too large to tackle. There is far too much ice to dredge the mouth of the river that will have to wait for the summer, but given the speed at which we have been operating don’t look for that to happen oh until maybe after the next flood.

But instead we seem content  to head down to that channel where God is trying to tell us that the river would like to go, and pulling the logs out from under a bridge busted all to hell .  I should add we are not going to get Alcan (Rio Tinto) to cut the flows into the Nechako, those flows are three times what they normally are during the winter and strangely enough the last time they released a large amount of water was in 1996 when we had our last flood. But then you might want to ask the question if any of those experts advising the city have done any work for Alcan?  

Common sense is common sense, or is it?

 I’m Meisner and that’s one man’s opinion.

I have a question; why is the city paying people (Guardian Angels) to sit at the west end of River road (to direct traffic, I presume) if this is needed, then why are they not sitting at the east end also? I have not seen them there anyway. Would'nt a barrier with signs and blinking lights give motorists the message that the road is closed?
metalman.
GUARDIAN IS SITTING ON RIVER ROAD AT THE ENTRANCE TO LAKELAND MILLS.THERE IS STILL ACCESS TO CN INTERMODAL AND THE RAILWAY MUSEUM.
Ben, Alcan has no choice but to dump water as the lake is high and they have to make a hole for spring melt. The lake is mainly high as they didn't have full generation for a time when one of their transmission lines was down.
It looks to me that we may have the wrong people in charge of our flood problem today. How can some specialists in water management in charge of supplying water for the city be qualified to look after a flood problem. I think it is time the city fathers put somebody in charge that will think outside the box. We are going to have this problem for years to come partley because of the water release from Alcan but mostley because of the amount of water that is and will continue to be in the resevoir because all of the trees that suck up the water are dead.If you do not believe me just ask any logger hou wet the bush is now compared to when the trees were alive...
They are going to make the same mistake vancouver did with dyking the fraser..You cant dyke a river that is eroding through sandy loam without dredging the channel out on a regular basis. Furhtermore i think the engineer who thought of putting gabion dykes up to protect a road from ice is sniffing too much glue in their office. You need to put concrete lock blocks up with a water barrier to do any significant results.
The north side of the river (50-80 feet from shore) is what traditionally carries 80% of the water volume through that whole area. Thats where the river cuts. I figure if you had a crane going along the north shoreline with a drop ball or something you know the water is at least 25 feet deep there and that is where you can get an open channel going. Anything on the south side of the river would not be getting to the deep water IMO.

Bull doze the good councilors yard and put a road in to facilitate the use of cranes and excavators working along that shore line to keep at least a 50 foot wide channel flowing, and that in turn should be enough to take the pressure off the south side of the river dikes, which if left alone will likely breach if not this week than for sure in the weeks to come.

IMO that is our last option at this point. It would likely cost $2 million dollars, but it would work and people would be working and paying their taxes. That is what the federal governments tax dollars are for if you lived in Central Canada.

Heck we pay 6-times that every day for our Afghanistan mission. So whats 4-hours Afghan costs to ensure BC's Northern Captial doesn't become the next Katrina-New Orleans?
IMO we want to encourage the river to flow on the north side.
Concrete blocks are not any better then the gabion diking IMO, but they might work well as emergency re-enforcemnt barriers easily moved into spots where the ice starts to put pressure on the gabion diking.
Hey Eagleone that may be a great idea, but that idea needs to come from an "EXPERT". When an "EXPERT" comes up with the idea maybe we might see some action. If it won't work I would like to hear why not.
I find it interesting how Brown and the media are calling this flood the 200 year high. Hello the flooding is caused by an ice dam. So if a ditch gets dammed in town causing some flooding. Will that also be a 200 year high? It will have the elevation. I believe the 200 year high is referring to a continuous very higher than normal flow of the river, not a dam. Drama.
Expert? An "Ex" is a has been and a "spert" is a drip under pressure.
"If you do not believe me just ask any logger hou wet the bush is now compared to when the trees were alive..."

and the hydrologists, who are also engineers who are saying the same thing. The 200 year flood plains will become 100 year and 50 year events ... the 50 year events will become 20 and 10 year events, and the 10 years events will become 2 year and even annual events ..... until the trees come back in again .....

So, planters ... get those trees planted ... province and licensees ... get the money to pay for the planting. Each year wasted is another year of high water events.
