Hi Roger,

This was published yesterday in the Midland Daily News:

Sanford Dam has been overrun with flood waters, though the dam's structure
is still intact.

"Water has gone all over and around the (Sanford) dam," said Midland County
Administrator/Controller Bridgette Gransden.

Despite being overrun, as of midday Wednesday, the structure of Sanford Dam
is still intact, Gransden said.

However, Sanford Dam's "fuse plug" — a spillway feature designed to wash
away in high flood conditions to keep the dam from collapsing — has been
washed out.

The Edenville Dam along the river failed — with the structure being
breached — at about 5:45 p.m. Tuesday and an alert from Midland County 911
at about 7 p.m. stated the failure of the Sanford Dam was imminent. Dave
Kook, a meteorologist with the National Weather Service, said the breaching
of the Edenville Dam has caused more water to be released into Sanford
Lake, also increasing the amount of water passing through Sanford Dam.

The Tittabawassee River is projected to fall to 30.30 feet by midnight
Thursday night, and to 23.40 feet by midnight Friday night. It is then
projected to be at 18.6 feet at midnight Saturday and 17.3 feet at midnight
Sunday.

It looks like you may be right about the Sanford Dam.

Stay safe!
