2020 Map of Otter

About this map

Otter sits at the heart of this high plains landscape within Custer National Forest, where the terrain is defined by a dense network of draws and divides. The prominence of Tooley Divide and named canyons like Hoover Draw and Colester Draw illustrates the complex drainage patterns of Powder River County. Water management is a primary feature of this era, visible through a high concentration of livestock and irrigation infrastructure including Lost Cr Reservoir, Happy Coulee Reservoir, and Fletcher Reservoir. Transport in this part of Montana remains tied to the natural contours of the land, with Otter Creek Rd and Bear Creek Rd serving as the primary arteries through the various townships. Numerous spring locations, such as 08S45E17AADC01 Spring and 08S45E27ABBC01 Spring, underscore the vital role of groundwater for local ranching and land use.
