Summary

The dam, designed by the USDA NRCS, serves multiple purposes including flood risk reduction and other water resource management functions. Standing at a height of 21 feet and stretching 730 feet in length, the earth dam is primarily made of stone core and soil foundation materials.

With a normal storage capacity of 42 acre-feet and a maximum storage of 58 acre-feet, Dobesh Jackson Dam plays a crucial role in managing water flow and mitigating flood risks in the area. The dam's low hazard potential and satisfactory condition assessment make it a reliable structure for safeguarding the surrounding community and environment. Despite being a non-USACE (United States Army Corps of Engineers) dam, it adheres to state regulations and undergoes regular inspections to ensure its operational integrity.

Water resource and climate enthusiasts can appreciate Dobesh Jackson Dam as a vital infrastructure piece that contributes to the overall water management strategy in Nebraska. Its strategic location on Sand Creek, along with its design features and regulatory oversight, demonstrate a commitment to sustainable water resource management and flood risk reduction in the region. As a private-owned dam with public benefits, Dobesh Jackson Dam exemplifies the importance of collaboration between various stakeholders to safeguard water resources and enhance climate resilience in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
