Located in La Plata County, Colorado, the Pine River Watershed P. R. 1, also known as the Archie Cruz Dam, was completed in 1967 by the USDA NRCS. This private dam serves as a crucial flood risk reduction structure in the region, with a height of 45 feet and a length of 530 feet. Situated along Spring Creek-TR, the dam has a normal storage capacity of 98 acre-feet and a maximum discharge rate of 588 cubic feet per second.

Although deemed to have a low hazard potential, the dam's condition was assessed as fair during the last inspection in September 2016. Despite being state-regulated and permitted, with regular inspections and enforcement in place, there are no associated emergency action plans or inundation maps prepared for this structure. With a risk assessment rating of High (2), it is evident that the Pine River Watershed P. R. 1 plays a critical role in managing water resources and mitigating flood risks in the area, making it an essential component of the local water infrastructure.
