Lamont is a private water resource located in Franklin, Idaho, serving the city of Preston. Built in 1948 for irrigation purposes, this earth dam on the Cub River and Bear River has a height of 67.6 feet and a storage capacity of 2040 acre-feet. Despite its fair condition assessment in 2018, the dam is considered to have a high hazard potential due to its location and design.

Managed by the Idaho Department of Water Resources, Lamont is subject to state regulations, inspections, and enforcement to ensure its safety and compliance. The dam's spillway type is noted as "None," raising concerns about its ability to manage excess water flow during periods of heavy rainfall or snowmelt. With a high risk assessment rating and a history of modifications or updates, Lamont remains a focal point for ongoing monitoring and risk management measures.

In the event of an emergency, the dam has an emergency action plan (EAP) that was last revised in 2011. However, it is unclear if the EAP meets current guidelines or if inundation maps have been prepared. With a high-risk profile and the potential for significant downstream impacts, stakeholders must remain vigilant in their efforts to ensure the safety and integrity of the Lamont water resource for both agricultural and environmental purposes.
