Heini is a privately owned irrigation dam located in Kremmling, Colorado, along the Pinto Creek-OS. Built in 1904, Heini stands at a height of 12 feet with a length of 100 feet, providing a storage capacity of 60 acre-feet for irrigation purposes. With a low hazard potential and a high risk assessment rating of 2, this dam is regulated and inspected by the Colorado Division of Water Resources to ensure its safety and compliance with state regulations.

Although Heini has not been rated for its condition assessment, it undergoes inspections every 6 years to monitor its structural integrity. The dam does not have a spillway but has a spillway width of 6 feet in case of overflow. With a surface area of 10 acres and a maximum discharge of 50 cubic feet per second, Heini plays a vital role in water resource management in the region. While not currently modified, the dam remains an essential part of the irrigation infrastructure in Grand County, Colorado.
