2011 Map of Delintment Lake

About this map

Mills Upper Ranch and Sherman Ranch anchor the high-country landscape of central Oregon as it appeared in the early 21st century. The terrain is defined by a complex network of seasonal and perennial drainages including Grindstone Creek, Copper Creek, and Silver Creek, which descend from the slopes of Iron Mountain. Water management is central to the area's geography, evidenced by the presence of Grindstone Reservoir, Williams Reservoir, and the namesake Delintment Lake in the southeast corner. Numerous named water sources such as Jimmy McCuen Spring and Tip Top Spring suggest the critical importance of reliable water for ranching and wildlife. A dense web of forest and ranch roads, including Mills Ranch Rd and Nat For Dev Rd 4175, provides the primary infrastructure through these remote reaches of the Ochoco National Forest area.
