Are the lakes in Eagle ID man-made. The ones in The Shores subdivision definitely seems somewhat man-made.. but IDK. Also, Isn't the Eagle/ Boise area prone to flooding??

While I'm not familiar with The Shores, I'm not aware of any natural lakes in the greater Boise area. A safe assumption is that any lake you see is man-made.

The surface water in the Boise metro comes from the Boise River. Its flows are regulated by three upstream dams so flooding is unlikely, but possible. I'm not aware of any uncontrolled flooding of the Boise River since Lucky Peak Dam was built in the 1950s. I have heard that Eagle Island used to be allowed to flood before it was developed.

This year was a weird spring and lots of April rain caused the Boise River to run at flood stage (8000 cfs) for a couple of weeks. Even that had minimal affects on the city, so it would take even more freakish circumstances to cause a flood.

Thanks.. I read the Boise area lake was prone to floods which requires extra homeowner insurance. This is why I was wondering why they would build a subdivision with about 20 lakes..The homes are nice but the lakes were concerning.. lol.

I haven't heard anything about a real flooding problem, but anywhere near any kind of water does often (not always) drastically increase homeowners insurance. I wanted to purchase a Boise home in 2010 that was about 250ft away from a small canal which was only about a foot deep during certain parts of the year - it looked like no flooding could ever happen and it wasn't near a major body of water at all. The quote for flood insurance was $320 per month and it was mandatory for a house valued at $125,000. I'm sure they aren't all that bad, but it is definitely something to look into.

Yes, prone to flooding and it happens once every 10 years or so.

There's a great map that shows what would happen in Boise if the river floods:

Hp1167, that is the coolest tool!!!

Very interesting to see that a property I showed today that is about 20 feet from the river does not flood even at almost twice the record water flows. It really depends a lot on where a property is along the river--some areas flood, some don't. This is really helpful--thank you!
