Blue Creek Valley

Blue Creek Valley is an 18 mi long valley located in northeast Box Elder County, Utah. It is endorheic with the Blue Creek Reservoir its low point located south in the valley's center.

The valley is nestled between three mountainous regions. The West Hills and Blue Spring Hills border it east and southeast. The south abuts the north of the Promontory Mountains, and the west is formed by a small north–south range, the North Promontory Mountains

The north of the valley borders the south of Idaho's Pocatello Valley.

Valley description
Because Blue Creek Valley is narrow, only 5-8 mi wide, small feeder creeks feed the region from the four cardinal directions. Blue Creek Reservoir is located in the center-south of the valley, with Blue Creek Spring located 2 mi northeast, the main feed to the reservoir.

The outlet of Blue Creek Reservoir trends south past Howell, Utah, into agricultural land. A peak associated with the north of the Promontory Mountains ends the valley's south, at the mountain range foothills. The mountain, Engineer Mountain, 5400 ft, and parts of the north Promontory Mountains drain north into the south border of Blue Creek Valley; southwest drainage from the mountain region drains southwest into the Bear River Bay section of the northeast Great Salt Lake.

Valley low point
The lowest elevation in the valley is south of Blue Creek Reservoir, its outlet, and to the farmland around Howell, Utah. Blue Creek Reservoir is at 4593 ft.
