Summary
Built in 1906, this Earth dam stands at 16 feet high and has a storage capacity of 260 acre-feet. With a spillway width of 32 feet and a valve outlet gate, the dam serves its primary purpose of irrigation for the surrounding area.
Despite its historical significance, Havens dam is currently assessed as being in poor condition with a low hazard potential. The last inspection in 2017 revealed the need for maintenance and improvements. While the risk assessment is moderate, with a DSAC risk rating of 3, there is no emergency action plan in place, and the dam does not meet current safety guidelines.
For water resource and climate enthusiasts, the case of Havens dam serves as a reminder of the importance of ongoing maintenance and monitoring of critical infrastructure. As climate change increases the frequency and intensity of extreme weather events, ensuring the safety and stability of dams like Havens is essential for protecting communities and ecosystems downstream. Collaborative efforts between state and federal agencies are needed to address the challenges of aging infrastructure and mitigate potential risks associated with deteriorating dams.

Dam Data Reference
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.
