I've been out of town and had no idea about this.

I remember that happening a few years ago. There would be random little ponds/streams in the streets.

Was kind of eerie.

Yeah lot of comparisons to 2018. It was a quick event but right at rush hour and lot of cars ended up stranded. I remember turning onto Blair St at 5am in summer of 2008 and hitting water. That was fun.

Anyone seen these pics? Mankato Minnesota, underground garages, full of water, you can see 6” of cars. Spencer Iowa, at Morton Buildings, bundles of lumber, 2x6x10’ , just guessing carried across HWY 18& 71. Then the after dumped them in the ditch. 2000 pounds, maybe.

I live in Sioux Falls but spent a good chunk of today in Rock Rapids, IA. If the Rock nears or breaks its all time record set 10 years ago, it will be awful. They already condemned and lost a ton of houses there the last time the town flooded, but this will get some more.

And it's not just the river. All the creeks and waterways and ditches are just so, so saturated from the past few days that there's no place for the water to go. Big Sioux River was also crazy high already early this afternoon.

Rock Valley is already starting evacuations of residential areas near the river on the NW side of town.

It's gonna be a **** show in several counties.

Husets Speedway, cancelled their races. Looks like all their campers parked at the race track underwater.

Six inches of rain at Sioux Center. There is a gauge south of Sioux Falls that has 13 inches in the last 24 hours.

KTIV showed a "radar-estimated" 20 inches in the last 48 hours along Hwy 18 in the Canton/Inwood area. Even if that's an overestimation, it's still insane.

It’s probably spot on. The gauge I saw was just west of Canton and had nearly 18 inches the last 48 hours. That’s incredible. In southeast Iowa, the most I’ve seen recorded was 11 inches. Last year, Kahoka, Missouri had 12 inches in one storm.

Going to be a scary night up north tonight. US 18 to US 14 will be the sweet spot. Another 3-7"+ in this area. Of course Mankato to Sioux Falls already got pummeled today too.

Watch the trickle down effect and river flooding on uncontrolled waterways like the Des Moines, Cedar River basins. There will be some major flooding... like Ft. Dodge. 1719028218438.png
Saylorville is expected to reach 867' by Independence Day. 884' is spillway, 892' with emergency bags. So some room to give. They'll kick up the outflow too and there will be bank full conditions in Des Moines, but ultimately Des Moines is fine for now. But if we get another setup like this anywhere in the basin to the north in the next few weeks, it'll be a big issue downstream.

Back in 200....4, I think. Early June. Well, there was one in June and a second in August. I think August was 13 inches, June was 6-8 and did more damage. Things were still cleared out when August happened. But it was the hilly driftless and raining so hard it was coming into the basement through the windows. It couldn't get away from the house fast enough even with gutters it was overflowing them and running down the siding . We had to go out and dig trenches in the mulch. And we were on top of a big ass hill. So the valleys on both sides completely flooded and culverts washed out. Carried hundreds of illegally dumped tires from the neighbors into our pasture. Fun summer hauling that **** out. One of the gullywashers happened during the day and we watched little rivers form in the horse pasture. Went down to the shin deep creek and saw it rise up to the road (idk, at least 10-15ft) and carry full grown trees through. Long story short, that volume of rain is nuts.

Fortunately, Red Rock has plenty of capacity.
