Perry, also known as Rauth Reservoir or Toedtlei Reservoir, is a private water resource in Weld County, Colorado, owned by USDA NRCS. Built in 1955 for irrigation purposes, this Earth-type dam stands at 35 feet tall and spans 2250 feet in length, with a storage capacity of 864 acre-feet. Located in Sterling, the reservoir is fed by Spring Creek and serves as a vital water source for the surrounding area.

Despite its low hazard potential and fair condition assessment, Perry has a high risk assessment rating of 2. The dam has not been inspected since July 2011, with an inspection frequency of 6 years. While it lacks certain emergency preparedness measures like an EAP and inundation maps, the reservoir meets state regulatory standards for permitting, inspection, and enforcement, ensuring its operational safety.

With a maximum discharge capacity of 23,000 cubic feet per second and a surface area of 40 acres, Perry plays a crucial role in the local water infrastructure. As climate change continues to impact water resources, monitoring and maintaining structures like Perry will be essential for ensuring water security and resilience in the region.
