Chester Wieser Ec #1 dam
Chester Wieser Ec #1
Chester Wieser Ec #1 is a privately owned earth dam located in Yuma, Colorado, along the North Sand Creek. Constructed in 1975 by the USDA NRCS, this dam stands at a height of 36 feet and has a storage capacity of 190 acre-feet. Its primary purpose is flood risk reduction, serving as a vital structure in protecting the surrounding area from potential flooding events.
With a low hazard potential and fair condition assessment, Chester Wieser Ec #1 plays a crucial role in managing water resources in the region. The dam's uncontrolled spillway has a width of 150 feet, and the maximum discharge capacity is 3200 cubic feet per second. Despite its age, the dam remains in operational condition, with the last inspection conducted in October 2010.
Managed by the Natural Resources Conservation Service, Chester Wieser Ec #1 is subject to state regulation and inspection, ensuring its continued safety and effectiveness in flood risk reduction. The dam's moderate risk assessment highlights the importance of ongoing maintenance and risk management measures to safeguard the surrounding community and water resources. As a key component of water resource infrastructure in the area, Chester Wieser Ec #1 exemplifies the critical role dams play in climate resilience and disaster preparedness.
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.
Plan around the weather

About Chester Wieser Ec #1
Where does the data for Chester Wieser Ec #1 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.
