Vonasek Dam 1835 dam
Vonasek Dam 1835
Vonasek Dam 1835, located in Holt, Nebraska, stands as a testament to the engineering prowess of Speece & Lewis Engineers and the USDA NRCS. Completed in 1958, this earth dam serves multiple purposes, including flood risk reduction and other water resource management functions. With a height of 19.7 feet and a storage capacity of 122.5 acre-feet, Vonasek Dam plays a crucial role in safeguarding the surrounding area from potential water-related hazards.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Vonasek Dam 1835 has demonstrated a satisfactory condition as of its last inspection in 2019. The dam's strategic location on TR-VERDIGRE CREEK and its proximity to the city of VERDIGRE underline its importance in the region. With a drainage area of 4.1 square miles and a maximum discharge capacity of 215 cubic feet per second, Vonasek Dam stands as a vital infrastructure for water resource management in the area.
As water resource and climate enthusiasts delve into the details of Vonasek Dam 1835, they can appreciate its role in flood mitigation and water storage within the region. With its stone core and soil foundation, this dam stands as a symbol of effective water management practices. Its presence underscores the importance of sustainable water resource infrastructure in ensuring the safety and well-being of local communities in Nebraska.

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 Vonasek Dam 1835
Where does the data for Vonasek Dam 1835 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 Hazard 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.
