Summary
Completed in 2011, this dam serves a primary purpose of "Other" and has a low hazard potential, with a satisfactory condition assessment as of November 2017. The dam's design includes a stone core and a soil foundation, with a storage capacity of 87 acre-feet and a surface area of 10 acres.
This dam is regulated by the Nebraska Department of Natural Resources (NE DNR) and undergoes regular inspections every 5 years to ensure its structural integrity. Despite its low hazard potential, the dam plays a crucial role in managing water resources in the area, particularly in relation to Cody Creek. The dam's emergency action plan (EAP) status and risk assessment details are currently not available, but the dam's overall risk management measures are likely in place to mitigate any potential threats.
With its completion in 2011, Progressive Swine Lagoon 1b Dam stands as a key water management structure in Greeley, Nebraska, contributing to the sustainable use of water resources in the region. As climate change continues to impact water availability and quality, the importance of well-maintained dams like this one cannot be understated in ensuring water security for both agricultural and environmental purposes. Its location, design, and regulatory oversight make it a noteworthy piece of infrastructure for water resource and climate enthusiasts to monitor and study in the ongoing efforts to address the challenges posed by a changing climate.

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.
