Policky Dam dam
Policky Dam
Policky Dam, located in Morrill County, Nebraska, is a private-owned structure designed by USDA NRCS for flood risk reduction purposes. Completed in 1969, this Earth-type dam stands at a height of 24 feet and spans 366 feet in length, with a storage capacity of 101.3 acre-feet. The dam's primary purpose extends beyond flood control, serving as a vital component in managing water resources in the region.
Operated under the oversight of the Nebraska Department of Natural Resources, Policky Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. With a low hazard potential, the dam has not been rated for its condition assessment, highlighting the need for ongoing monitoring and maintenance. Despite its modest size in terms of storage and drainage area, the dam plays a crucial role in mitigating flood risks and maintaining water resources in the North Platte River watershed.
As a key feature in the local water management infrastructure, Policky Dam serves as a testament to the collaborative efforts between private ownership, state agencies, and design professionals. Its location in Lisco, Nebraska, and proximity to the North Platte River underscore its importance in safeguarding the surrounding community against potential flood events. With a focus on public safety and resource conservation, Policky Dam stands as a vital asset in the region's efforts to adapt to changing climate patterns and ensure sustainable water management practices.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Policky Dam
Where does the data for Policky 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.
