Clark #2 dam
Clark #2
Clark #2 is a privately owned earth dam located in Huerfano, Colorado, with a primary purpose of fire protection, stock, and small fish pond. Built in 1907, the dam stands at a height of 27 feet and spans a length of 972 feet, providing a storage capacity of 1373 acre-feet. Situated on the Pope Arroya-TR river or stream, the dam serves multiple purposes including flood risk reduction and irrigation for the surrounding area.
Despite its age, Clark #2 has a low hazard potential and has not been rated for its condition assessment. The dam has not been inspected since May 1989, highlighting the need for increased monitoring and assessment. With a high risk assessment rating, there is a need for comprehensive risk management measures to ensure the safety and integrity of the structure in the face of potential climate change impacts on water resources.
Enthusiasts of water resource management and climate change adaptation will find Clark #2 an intriguing case study, showcasing the importance of proactive maintenance and monitoring of aging infrastructure in the face of evolving environmental conditions. The dam's location in a high-risk area underscores the need for robust emergency preparedness plans and risk management strategies to mitigate potential hazards and ensure the continued functionality of the structure for fire protection, irrigation, and other critical purposes.

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 Clark #2
Where does the data for Clark #2 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.
