Hammond, also known as Little Valley Dam, is a private water structure located in Ovid, Idaho. Managed by the Natural Resources Conservation Service, this dam was completed in 1933 for irrigation purposes along Hammond Creek and the Bear River. With a height of 33.3 feet and a storage capacity of 645 acre-feet, Hammond plays a vital role in supporting agricultural activities in the region.

Despite its fair condition assessment and significant hazard potential, Hammond is regulated, inspected, and enforced by the Idaho Department of Water Resources. The dam features an uncontrolled spillway and a drainage area of 1.9 square miles, making it crucial for managing water flow and preventing potential flooding. With a moderate risk assessment rating of 3, ongoing risk management measures are essential to ensure the safety and functionality of this important water resource infrastructure in Bear Lake County.

As part of the Sacramento District, Hammond is subject to regular inspections every 4 years, with the last assessment conducted in August 2017. With its strategic location and historical significance in water resource management, Hammond stands as a testament to the enduring importance of sustainable irrigation practices and the critical role of private entities in maintaining key water infrastructure in Idaho.
