Located in Hay Press Park in South Fork, Colorado, Dam #1, also known as Hay Press Park - South Dam, stands as a testament to engineering excellence since its completion in 1922. Designed by Carl A. Gould, this private earth dam serves multiple purposes, including hydroelectric power generation, fish and wildlife conservation, and recreational activities. With a height of 27 feet and a length of 395 feet, the dam creates a reservoir with a storage capacity of 269 acre-feet, providing essential water resources for the surrounding area.

Situated on Goose Creek-TR, Dam #1 plays a vital role in managing water flow and supporting the local ecosystem. With a spillway width of 11 feet and an uncontrolled spillway type, the dam has a low hazard potential and a fair condition assessment as of its last inspection in July 2017. The dam's moderate risk level is mitigated by regular inspections, enforcement, and emergency preparedness measures. Its picturesque location and historical significance make Hay Press Park - Dam #1 a must-visit destination for water resource and climate enthusiasts seeking to appreciate the intersection of nature and human ingenuity in water management.
