Summary
Completed in 1950, this dam stands at a height of 25 feet and has a storage capacity of 94 acre-feet. The reservoir created by the dam covers 7 acres and drains an area of 65 square miles, providing a serene setting for outdoor enthusiasts to enjoy various water-based activities.
Despite being privately owned, Biggs Lower Lake Dam has a high hazard potential, highlighting the importance of regular maintenance and monitoring. The dam is not currently regulated by the state and has not been inspected or assessed for its condition. The lack of an Emergency Action Plan (EAP) and updated contact information raises concerns about the preparedness for potential emergencies and the need for risk management measures. As a fan of water resources and climate, staying informed about the status of dams like Biggs Lower Lake Dam is crucial in ensuring the safety and sustainability of our water infrastructure.
With its picturesque location and recreational opportunities, Biggs Lower Lake Dam serves as a valuable asset to the community. However, the lack of state regulation and inspection raises important questions about its safety and maintenance. As water resource and climate enthusiasts, advocating for proper oversight and management of dams like Biggs Lower Lake Dam is essential in safeguarding our water resources for future generations. Stay engaged, stay informed, and support efforts to ensure the sustainability and safety of our water infrastructure.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
