    Flew in to the Freemont to pick up my daughter and her roommates who attend Midlands. The flooding is worse than I thought. That tiny airport was crazy busy.

    My wife just caught a flight to Wahoo and a friend is going to pick her up and take her home. My office is by the airport and I can hear them taking off the last 2 days. Pretty bad when have to fly to make a 3 mile trip.

    Supposed to get pretty warm this week. Still a lot of snow left to melt here in northern iowa. The cold temps on friday froze the ponds slightly and kept more from melting. Allowed things to go down some up here and buy time to get the rivers situated for the next wave coming.

    The HESCO barriers are getting put up.
    I haven't heard a call for sandbagging yet.

    Saw that. I doubt we will see one with the forecast crest only being 18.5. My personal opinion is sandbagging isn't needed much anymore unless it gets above 25'.

    18.5 really doesn’t do a lot anymore. It was like 24 just 2 years ago

    Home for the first time since Friday. Drove 65 miles to find an open bridge for a normally 5 mile drive.

    Actually was just below 22 in 2016 and that didnt do a lot. I think if it gets above 24 or around that, that's when it goes over the levee in the time check area.

    If the river goes crazy like it did in 16, that's potentially another week schools will be closed. The school year will end damn near close to July.

    Lehigh was flooding. I hope the Riverside Tap was not hit.

    Is CR ever getting a flood wall or are the HESCO barriers the current and future flood wall?

    Currently Truman lake is 9 feet above normal. The highest I have seen was about 15-16 above normal so it has a way to go. When you think about the size of that lake, that's a lot of water. I'll most likely take a drive down that way in a few weeks.

    Eventually. The city council dug in their heels when the Army Core said it wasn't economical to pay for walls on both the west and east side. So total cost of the project is something like an obscene $750M over 20+ years. It sounds like the completed portion protecting the NewBo area worked as intended though.

    They'd probably open up the outflow i assume, once it hit that point. From what i can see the peak outflow is more than double what it is currently forecast to be

    Outflow is determined by the Racoon River since that can't be controlled. They won't open the gates moer if the Racoon is still in major flood stages

    I found this very interesting about the Saylorville Dam:
    "Under normal conditions, the dam releases water through a gated 22-foot diameter-conduit located at the base of the dam. The conduit’s maximum outflow is 21,000 cfs. Since the 1993 flood, the Corps has incorporated an inflatable dam (pneumatic crest gates) that, when inflated, provides an additional 6 feet of spillway elevation to 890’ NGVD29. However, if the pool level is forecast to rise above 890’ NGVD29, the inflatable dam will be lowered as we do not have the legal authority to maintain the pool above 890’ NGVD29."

    However the can submit a deviation for above 890'.
