Nee-Noshe dam
Nee-Noshe
Nee-Noshe, located in Lamar, Colorado, is a privately owned irrigation dam on the Arkansas River-OS with a significant storage capacity of 60,618 acre-feet. Built in 1896, this earth dam stands at 25 feet tall and stretches 1600 feet in length, serving multiple purposes including fish and wildlife habitat, irrigation, and recreation. The dam's spillway, with a width of 100 feet, is uncontrolled, and it has a moderate risk assessment rating of 3.
Managed by the Colorado Department of Water Resources, Nee-Noshe is subject to state regulation, inspection, and enforcement to ensure its structural integrity and operational safety. The dam's condition assessment in July 2020 deemed it satisfactory, with a hazard potential classified as significant. With a history dating back over a century, Nee-Noshe continues to play a crucial role in water resource management and agricultural irrigation in the Kiowa County region.
Water resource and climate enthusiasts interested in the intersection of infrastructure, natural habitats, and water management would find Nee-Noshe a fascinating case study. Its historical significance, multi-use purposes, and state-regulated operations highlight the complex balance between human needs and environmental conservation. As a key feature on the Arkansas River-OS, Nee-Noshe's role in sustaining local ecosystems and supporting agricultural activities underscores the importance of responsible dam management in the face of evolving climate challenges.

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 Nee-Noshe
Where does the data for Nee-Noshe 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 Significant 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.
