Ten Mile Creek runs over

The Ten Mile Creek in the Helena Valley is flooding its banks in some areas.

Lewis & Clark County Disaster and Emergency Services coordinator Paul Spengler says parts of the Helena Valley sit in a natural floodplain.

He says because of that, the Helena valley is at high risk for flooding.

"The streams are very low and it doesn't take much for the water to jump the banks. Especially in the case of Ten Mile, which is a perched stream, meaning it stands up above the surrounding terrain. The water doesn't hang around the banks, it goes down hill into the valley. Everything ends up in Lake Helena which happens to be the lowest spot in the Helena Valley," said Spengler.

Spengler recommends purchasing flood insurance for your home. He says these policies take 30 days to become active.

If you are unsure if you are living in a floodplain you can contact the Disaster & Emergency offices at 406.447.8285.
