Point of Rock is a privately owned dam located in Cassia, Idaho, along Marsh Creek and the Snake River. Built in 2004, this earth dam stands at a height of 30.2 meters and has a storage capacity of 358 acre-feet. With a drainage area of 87.9 square kilometers and a spillway width of 18 meters, Point of Rock plays a significant role in managing water resources in the region.

Managed by the Idaho Department of Water Resources, Point of Rock is subject to state regulation, inspection, and enforcement to ensure its safety and compliance with standards. The dam is classified as having a significant hazard potential, but its condition was assessed as satisfactory during the last inspection in July 2017. With its primary purpose listed as "Other" and utilizing stone core types and rock and soil foundation, Point of Rock serves as a key structure for water management and flood control in the area.

Despite being privately owned, Point of Rock provides essential functions for the community and surrounding environment. With its moderate risk assessment and satisfactory condition, this dam stands as a crucial infrastructure for water resource and climate enthusiasts to monitor and support for the continued resilience of the region.
