Shadow View 2nd Addition Dam dam
Shadow View 2nd Addition Dam
Shadow View 2nd Addition Dam, located in Omaha, Nebraska, is a local government-owned structure designed for flood risk reduction on the TR-Boxelder Creek. Completed in 2002, this earth dam stands at a height of 29 feet with a hydraulic height of 29 feet and a structural height of 34 feet. The dam measures 325 feet in length, providing a maximum storage capacity of 21.6 acre-feet and a normal storage of 11.1 acre-feet, covering a surface area of 1.4 acres and draining an area of 0.08 square miles.
Owned and regulated by the Nebraska Department of Natural Resources, Shadow View 2nd Addition Dam has a low hazard potential and is in satisfactory condition as of the last assessment in June 2019. The dam has not been modified since its completion and does not have a spillway. With a maximum discharge capacity of 138 cubic feet per second, this structure plays a crucial role in managing flood risks in the area. Its emergency action plan was last revised in May 2002, and the dam is inspected every five years to ensure its continued safety and functionality.
Overall, Shadow View 2nd Addition Dam serves as a vital infrastructure for flood risk reduction in the Douglas County region of Nebraska. Its strategic location on the TR-Boxelder Creek, combined with its design and functionality, helps protect the surrounding area from potential flooding events. As climate change continues to impact water resources and weather patterns, structures like this dam play a crucial role in mitigating the risks associated with extreme weather events and ensuring the safety and security of the community.

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 Shadow View 2nd Addition Dam
Where does the data for Shadow View 2nd Addition 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.
