Summary
Completed in 1985, this earth dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 12 feet and a length of 400 feet, it has a storage capacity of 60 acre-feet and covers a surface area of 10.5 acres. The dam is situated on the South Branch Heart River and has a spillway width of 100 feet.
Despite its low hazard potential, Bock Dam East is considered to have a moderate risk level. The dam features a vertical lift outlet gate and is inspected regularly to ensure its safety and functionality. While its condition is currently not rated, the dam's risk management measures are in place to mitigate potential issues. With its strategic location and design, Bock Dam East plays a crucial role in water resource management and climate resilience efforts in the region.
Enthusiasts of water resources and climate change will find Bock Dam East to be a fascinating example of infrastructure designed for multiple purposes in a dynamic environmental setting. Its role in fire protection, stock maintenance, and small fish pond management highlights the importance of sustainable water resource management. As a regulated structure with moderate risk, the dam's design and management serve as a valuable case study for enthusiasts interested in the intersection of water resources, climate resilience, and infrastructure development.

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.
