Lake Arrowrock Reservoir, located in southwestern Idaho, has a fascinating history that dates back to the late 19th century. The reservoir was originally created as part of a major irrigation project in the Boise River Basin, designed to support agricultural development in the region. Construction on the dam began in 1911 and was completed in 1915, with the primary goal of regulating river flows and providing water storage for irrigation purposes.
The dam, which stands at an impressive height of 350 feet, was considered an engineering marvel at the time of its construction. It was built using a combination of concrete and rock fill materials, making it one of the largest dams of its kind in the United States. The reservoir itself covers over 4,000 acres and has a storage capacity of approximately 300,000 acre-feet of water.
In addition to its role in irrigation, Lake Arrowrock has also played a significant role in providing flood control for the surrounding area. The dam’s ability to regulate water flow in the Boise River has helped prevent catastrophic flooding in downstream communities and has contributed to the overall safety and security of the region.

These efforts have helped maintain the ecological balance of the region and have ensured that future generations will be able to enjoy the beauty of Lake Arrowrock for years to come.
In conclusion, Lake Arrowrock Reservoir stands as a testament to the ingenuity and vision of those who worked to create it over a century ago. From its humble beginnings as an irrigation project to its current status as a beloved recreational destination, the reservoir has played a vital role in the history and development of southwestern Idaho.
