Summary
This dam, situated on Lost Creek, has a height of 25 feet and a storage capacity of 214 acre-feet. With a surface area of 16 acres and a drainage area of 442 square miles, this dam plays a significant role in managing water resources in the region.
Despite its recreational focus, Mcdaniels, Huelin Dam is classified as having a high hazard potential, indicating the importance of proper maintenance and monitoring. The dam has not been inspected since 1979, and its condition is currently listed as "Not Rated." While the dam has not been subjected to state regulation or permitting, it is crucial for water resource and climate enthusiasts to advocate for regular inspections and risk assessments to ensure the safety and sustainability of this structure.
Given the potential risks associated with high hazard dams, there is a need for increased attention and oversight of Mcdaniels, Huelin Dam. As a crucial component of the local water infrastructure, this dam requires comprehensive assessments, emergency action plans, and regular maintenance to mitigate potential hazards and ensure its long-term functionality. Water resource and climate enthusiasts can play a vital role in advocating for the necessary resources and measures to safeguard this important asset for the community and the environment.

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.
