If Saylorville does happen to flood, any idea how far the flood water could impact Ankeny/Johnston?
I think the only part of Johnston that really floods are a few houses in the development by the Johnston soccer fields.

It's been 6 years since Saylorville's level was raised significantly. A lot of the beach has grown in with weeds/plants the last couple summers. It'll be nice to get some beach back if that vegetation gets wiped out.

Ankeny and Johnston…Minimal.

Downtown and Des Moines proper along the Des Moines River are the areas in trouble. In 1993 the Valley Junction area also flooded badly from the Racoon River, but I think that levee has been rebuilt bigger since then.

Likely, but this isn't it. I don't think it was supposed to storm until middle of the night

This is like a little appetizer. Mesoscale discussion seemed less confident overnight now. Idk, storm watch only goes til 1 and I thought the main thing wasn't til 2-3.

Ankeny is a higher elevation (for the most part) than the dam. Parts of Johnston on the other would be proper Facked
The only homes that might be affected in Johnston would be the ones right by the soccer fields. Those are relatively new builds so I can't imagine they would have built them if they were in any flood danger?

Other than that there's not really much else in Johnston except for those industries south of Saylorville and north of I-80. I've seen that area underwater a couple of times in my life including the little league fields there just off I-80.

If the water ever gets high enough to flood up to those businesses on NW Beaver then RIP to a large portion of the Des Moines metro.

Don't know about the rest of Iowa, but the forecast for central Iowa tomorrow (Tuesday) is calling for 80% chance of rain during the day and 80% during the night. Those will be thunderstorms, though, so it could be heavy or light in certain areas.
