Green Tank


May 1, 2024

Green Tank is a federal-owned earth dam located in Modoc, California, completed in 1975 for fire protection, stock, and small fish pond purposes. With a height of 8 feet and a length of 710 feet, this dam has a storage capacity of 480 acre-feet and serves a drainage area of 1.6 square miles. The dam features an uncontrolled spillway with a width of 30 feet and has a low hazard potential.

Managed by the Forest Service, Green Tank has not been inspected since August 2010, with a scheduled inspection frequency of 10 years. Despite its condition being rated as "Not Rated," the dam's risk assessment is moderate, indicating a level 3 risk. With no emergency action plan in place and limited risk management measures identified, the dam presents a potential need for further evaluation and preparation in the face of changing climate and water resource challenges.

For water resource and climate enthusiasts, Green Tank serves as a vital structure to monitor and assess in the context of evolving environmental conditions. With its primary purpose of fire protection and water storage, the dam's management and safety protocols will be crucial in ensuring its resilience to potential hazards. As climate impacts continue to unfold, the need for updated inspections, risk assessments, and emergency preparedness measures at Green Tank becomes increasingly imperative to safeguard both the dam's integrity and the surrounding ecosystem.
