Summary
Completed in 1967, this dam serves a primary purpose of flood risk reduction and has a normal storage capacity of 29 acre-feet. With a height of 33 feet and a length of 570 feet, Rock Creek 1-7 is a vital infrastructure providing protection to the surrounding area with a low hazard potential and a satisfactory condition assessment as of June 2016.
Situated on TR-ROCK CREEK, this dam covers a drainage area of 0.3 square miles and has a maximum discharge capacity of 1,016 cubic feet per second. The dam's construction primarily consists of earth and stone materials on a soil foundation, ensuring its structural integrity. Despite being a relatively smaller dam, Rock Creek 1-7 plays a crucial role in managing water resources and mitigating flood risks in the region.
Maintaining a regular inspection frequency of 5 years, Rock Creek 1-7 remains in a satisfactory condition, ensuring its effectiveness in flood risk reduction. With its strategic location and design, this dam continues to uphold its purpose of safeguarding the local community from potential water-related hazards. For water resource and climate enthusiasts, Rock Creek 1-7 serves as a noteworthy example of sustainable water management practices in Nebraska.

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.
