Munger #1 dam
Munger #1
Munger #1, located in Weld, Colorado, is a privately owned Earth dam completed in 1902 for irrigation purposes on the South Platte River. Standing at 10 feet high and 1050 feet long, the dam has a storage capacity of 60 acre-feet, with a normal storage level of 40 acre-feet. Although the dam has a low hazard potential, it is categorized as high risk due to its condition not being rated, indicating a need for further assessment and potential risk management measures.
Despite being last inspected in 1984 with a frequency of every 6 years, Munger #1 remains in operation with no reported structural issues or modifications over the years. With a spillway width of 30 feet and a maximum discharge of 79 cubic feet per second, the dam serves as a crucial water resource for irrigation in the area. While the dam's emergency action plan status and adherence to guidelines are unspecified, its location and purpose make it a significant asset for water management and climate resilience efforts in the region.
As water resource and climate enthusiasts continue to monitor and assess the state of Munger #1, its role in supporting agricultural activities and water sustainability in the South Platte River watershed underscores the importance of proactive maintenance and risk mitigation strategies. With its historical significance and operational longevity, ensuring the safety and efficiency of Munger #1 will be key in safeguarding both local water supplies and the surrounding ecosystem in the face of changing climatic conditions and water resource demands.
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 Munger #1
Where does the data for Munger #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.
