Summary
Completed in 1939, this earth dam serves primarily for recreational purposes, offering a serene oasis for water and climate enthusiasts alike. The dam's impressive dimensions of 20 feet in height and 400 feet in length contribute to its significant hazard potential, prompting regular inspections and a high-risk assessment status.
Despite its historical significance and recreational appeal, Weimer Lake Dam currently faces challenges related to its condition assessment, which was deemed poor as of November 2011. With a risk assessment rating of high (2), the dam's structural integrity and safety measures are under scrutiny. The absence of a spillway and outlet gates further compound these concerns, highlighting the importance of ongoing risk management and maintenance efforts to ensure the dam's long-term viability and the safety of surrounding communities.
As water resource and climate enthusiasts continue to appreciate the tranquil beauty of Weimer Lake Dam and its surrounding environment, it is crucial to recognize the importance of proactive measures in safeguarding this vital infrastructure. With a significant hazard potential and a high-risk assessment, stakeholders must prioritize regular inspections, maintenance, and risk management strategies to uphold the dam's structural integrity and ensure the safety of all those who benefit from its recreational offerings.

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.
