Melvin Anderson Dam dam
Melvin Anderson Dam
Melvin Anderson Dam, located in Orleans, Nebraska, is a privately owned structure that plays a crucial role in managing water resources in the area. Built in 1955, this earth dam stands at a height of 11.4 feet and has a storage capacity of 70.7 acre-feet. It is designed to control School Creek and has a drainage area of 5.95 square miles, providing essential flood protection and water supply for the region.
Managed by the Nebraska Department of Natural Resources, Melvin Anderson Dam is classified as a low hazard structure with a fair condition assessment. While it has a spillway type and width unspecified, the dam has been regularly inspected, with the last assessment conducted in November 2014. Despite its age, the dam continues to serve its primary purpose effectively, showcasing the importance of proper maintenance and oversight in water resource management.
The dam's location within Harlan County, Nebraska, highlights its significance in the local water infrastructure network. With its state-regulated status and adherence to inspection, permitting, and enforcement protocols, Melvin Anderson Dam stands as a testament to responsible dam ownership and operation. For water resource and climate enthusiasts, this structure serves as a vital component in ensuring water security and flood control in the region, showcasing the intersection of infrastructure and environmental stewardship.
Dam data reference
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 Melvin Anderson Dam
Where does the data for Melvin Anderson 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.
