Summary
Completed in 2009, this earth dam stands at a height of 26.2 feet and has a storage capacity of 51.5 acre-feet, with a normal storage level of 24.5 acre-feet. Its low hazard potential and satisfactory condition assessment make it a reliable structure for managing water resources in the area.
Managed by the Nebraska Department of Natural Resources, Larry Bohlken Dam is subject to state regulation, permitting, inspection, and enforcement. It serves as a crucial component of water resource management in the region, with a drainage area of 0.18 square miles and a maximum discharge capacity of 42 cubic feet per second. The dam's strategic location and design contribute to its effectiveness in controlling water flow and preventing erosion along TR-Muddy Creek, showcasing its importance in mitigating the impacts of climate change on the local ecosystem.
With a focus on grade stabilization, Larry Bohlken Dam plays a significant role in protecting the surrounding landscape from erosion and flooding. Its satisfactory condition, regular inspection schedule, and low hazard potential underscore its reliability and importance in water resource management. As climate change continues to impact the region, structures like Larry Bohlken Dam will be essential for ensuring the sustainable management of water resources and protecting the local community from the adverse effects of extreme weather events.

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.
