Standing Bear Dam - Flower Hill Cemetery Protective Levee Dam
Standing Bear Dam - Flower Hill Cemetery Protective Levee
Standing Bear Dam - Flower Hill Cemetery Protective Levee, also known as Standing Bear Lake, is a vital flood risk reduction structure located in Omaha, Nebraska. Owned and managed by the US Army Corps of Engineers, this earth dam was completed in 1973 and stands at a hydraulic height of 23 feet, with a length of 1480 feet and a volume of 328,000 cubic feet. It serves the primary purpose of flood risk reduction along the TR Papillion Creek, with a normal storage capacity of 1500 acre-feet and a maximum storage of 7300 acre-feet.
This low hazard potential dam is continuously monitored and maintained by the US Army Corps of Engineers to manage and mitigate potential risks associated with flooding events. The agency works closely with local emergency managers to raise awareness of the dam and support the development of emergency plans and evacuation procedures in case of a dam-related emergency. The emergency action plan is regularly updated, and risk management measures are prioritized to ensure the dam's structural integrity and the safety of surrounding communities. More detailed information on this critical infrastructure will be added at a future time to enhance risk assessment and management strategies.
Overall, Standing Bear Dam plays a crucial role in protecting the region from flooding events and requires ongoing maintenance and monitoring to ensure its functionality and safety. As part of the US Army Corps of Engineers' efforts to address all types of flood risk associated with the dam, it is essential to engage with local stakeholders and emergency managers to enhance preparedness and response capabilities in case of a dam-related emergency. With its strategic location and purpose, this protective levee stands as a key asset in safeguarding the community and the environment from the impacts of severe weather events and potential flooding risks.
Inside the reservoir
The real shoreline of this water body, with a depth model scaled so the basin holds exactly its recorded storage. Drag to orbit, scroll to zoom, and use the slider to drain and refill it. Click anywhere on the basin for the modelled depth there.
NID normal pool storage (1500 AF) over this shoreline implies a 40 ft basin, deeper than the 23 ft dam. Depth capped to the dam; storage shown is modelled, not NID.
How this is built. The shoreline is the National Hydrography
Dataset polygon for this water body (“Standing Bear Lake”),
matched to the dam by proximity and confirmed by comparing its area with the
National Inventory of Dams surface area (agreement 0.612×).
Depth is modelled, not surveyed: the basin is shaped by distance from
shore — deep in open water, shallow in the bays — and scaled so its
volume equals the recorded storage. No national bathymetric survey exists for
US reservoirs. Treat the shoreline, area and volume as measured, and the depth
distribution as an informed approximation.
Above normal pool, water is shown rising within the normal-pool
shoreline. Where it would actually spread depends on the surrounding
terrain, which is not modelled here — a reservoir in a steep canyon barely
widens, one on flat ground can spread a long way. This is a depth and volume
figure, not an inundation map. Official inundation mapping for a dam
comes from its Emergency Action Plan.
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 Standing Bear Dam - Flower Hill Cemetery Protective Levee
Where does the data for Standing Bear Dam - Flower Hill Cemetery Protective Levee 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 below 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.

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.
