Hermit #4 dam
Hermit #4
Hermit #4, located in Hinsdale, Colorado, is a privately owned earth dam completed in 1947 for recreational purposes such as fish and wildlife pond and recreation. The dam has a height of 10 feet and a hydraulic height of 12 feet, with a length of 290 feet and a storage capacity of 356 acre-feet. It is situated on the South Clear Creek, within the Sacramento District.
Despite its low hazard potential and satisfactory condition assessment, Hermit #4 poses a high risk due to its proximity to residential and recreational areas. The dam has not been modified in recent years and lacks spillway infrastructure. With a drainage area of 4 square miles and a maximum discharge capacity of 2420 cubic feet per second, any potential failure could have significant downstream impacts. Regular inspections are conducted, with the last assessment reported in July 2020.
Water resource and climate enthusiasts interested in the intersection of dam safety, recreational activities, and environmental conservation should keep an eye on Hermit #4. As a privately owned structure regulated by the Colorado Department of Water Resources, its condition and risk management measures are crucial for ensuring public safety and safeguarding the surrounding ecosystem. With the potential for high-risk scenarios, ongoing monitoring and maintenance of this dam are essential to prevent any adverse consequences for the community and environment.
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 Hermit #4
Where does the data for Hermit #4 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.
