Early 20th century hollow core cement dam held up well.

Credit to how they made them back then which wasn't always sound.

What ir needed was some steel barriers in front of the gates to keep them from getting clogged by downed trees during the flood event.

The part that gave was the earthen embankment along the left (facing downstream) side of the dam structure that acted as an emergency spillway.

That was what relieved the pressure on the structure.

Of course, once the flood subsides that old dam is now toast and has to go.

Could have been much worse tho.

The one on the Blue Earth River was an OG hydro dam still generating until the other day.

It was part of the early electrification of the MN countryside.

But, yeah, it was old and dams aren't built to last forever due to a variety of factors (usually sedimentation build up).

Many of the ones built in WA/OR were of the WTF did you really need it there variety.

It's a case by case thing and that particular MN one was legit with a real need that was met at the time.
