The Lake & the River
Sakakawea, the Missouri, and the dam that made both.

When the water is worth it
The lake and the river run on their own calendar. Here is roughly what each season gives you — and what it takes away.
Spring
Ice off, water upThe ice goes off and the runoff comes down; the dam is releasing and the river below runs cold and fast. Eagles still work the open water. Shore access roads can be soft.
Summer
Peak, but go earlyThe long-light season — warm water, pelicans on station, the marinas at Garrison and Fort Stevenson busy. Get out early: when the wind gets up, the lake builds steep, short waves by afternoon.
Fall
The best of itThinner crowds, low hard light, water still workable, and the far shore sharper than it is all summer. Cold fronts arrive with real wind, so watch the sky if you are on the water.
Winter
Come preparedThe lake becomes a different place — locked, white and enormous. Open water below the dam draws eagles. There is no shelter anywhere on that shoreline; dress for it or come in another season.
The wind decides more than the thermometer does out here. The wind is a feature — read that before you plan around it.
Lake Sakakawea Is Bigger Than You Think

What the Garrison Dam Actually Did
Flood control, power, and the land that went under.
Fort Stevenson State Park

The Missouri Below the Dam
A different river downstream, and why.
