Thiltgas Gerweck Dam dam
Thiltgas Gerweck Dam
Thiltgas Gerweck Dam, located in Richardson, Nebraska, is a vital water resource structure designed by Leland Jackson of USDA NRCS in 1980. The dam, owned by the local government, serves multiple purposes including flood risk reduction and others, with a primary focus on water management in the region. Standing at a height of 38 feet and a length of 280 feet, the Earth type dam holds a storage capacity of 71 acre-feet and covers a surface area of 2 acres.
Managed by the Nebraska Department of Natural Resources, the dam is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and operational safety. Despite its poor condition assessment in 2017, the dam continues to play a crucial role in protecting the area from potential flooding and managing water resources effectively. With a maximum discharge capacity of 53 cubic feet per second, the dam contributes to the overall water management strategy in the region and supports the surrounding ecosystem.
Situated on TR-Bean Creek, the Thiltgas Gerweck Dam is a key infrastructure in the area, overseen by local and state agencies to meet the water management needs of the community. With its historical significance and impact on the local environment, the dam remains a critical asset for flood control, water storage, and ecological preservation efforts. As water resource and climate enthusiasts, understanding the importance and function of structures like the Thiltgas Gerweck Dam sheds light on the complex and interconnected nature of water management in our changing climate.

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 Thiltgas Gerweck Dam
Where does the data for Thiltgas Gerweck 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 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.
