Summary
This private-owned Earth dam stands at a height of 19.5 feet and has a storage capacity of 182 acre-feet. Despite its low hazard potential, the dam's condition assessment was rated as poor during its last inspection in 2013.
The dam's designer, W. Carlos Powell, envisioned a structure that not only provides recreational opportunities but also serves as a vital component of the local water resource management system. With a surface area of 35 acres and a normal storage capacity of 170 acre-feet, Bolack No 1 Dam contributes to the water supply and management efforts in San Juan County. However, its poor condition assessment raises concerns about the need for maintenance and potential upgrades to ensure the safety and efficiency of the dam.
As water resource and climate enthusiasts monitor Bolack No 1 Dam's risk assessment and condition, it is crucial to recognize the role that such structures play in balancing water usage for both recreational and practical purposes. With state regulatory agencies overseeing its operation and enforcement, this dam serves as a reminder of the delicate balance between water management and environmental stewardship in the face of changing climate conditions.

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.
