Henke Dam dam
Henke Dam
Henke Dam, located in Beaver Crossing, Nebraska, is a private earth dam completed in 2000 for fire protection, stock, and small fish pond purposes along the TR-W FK Big Blue River. With a height of 13.9 feet and a storage capacity of 79.3 acre-feet, this dam serves as a vital resource for the local community. Despite its low hazard potential, the dam's condition was assessed as poor during the last inspection in May 2017, raising concerns about its long-term structural integrity.
Managed by the Nebraska Department of Natural Resources, Henke Dam is subject to state regulation, permitting, inspection, and enforcement. The dam's location in Seward County, Nebraska, within Congressional District 01, underlines its importance in local water resource management. The dam's associated structures, spillway type, and outlet gates were not specified, indicating potential areas for further improvement and risk mitigation measures to ensure the safety and efficiency of the dam for its intended purposes.
Water resource and climate enthusiasts will find Henke Dam's data intriguing, as it highlights the intersection of infrastructure, water management, and environmental stewardship in a rural setting. The dam's role in providing essential services such as fire protection and stock watering underscores its significance for both human needs and ecological sustainability. With a focus on enhancing the dam's condition assessment, risk management measures, and emergency preparedness, stakeholders can work towards ensuring the long-term viability and resilience of Henke Dam in the face of changing climate patterns and water resource challenges.

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.
- 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.
- 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.
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, environmental 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.

About Henke Dam
Where does the data for Henke Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
