Hodgson-Harris dam
Hodgson-Harris
Hodgson-Harris, a private-owned structure located in Boulder, Colorado, is a significant water resource for the area. This earth-type dam, completed in 1906, serves as a Fish and Wildlife Pond with a storage capacity of 168 acre-feet. The dam stands at a height of 23 feet, with a spillway width of 10 feet, and a maximum discharge capacity of 275 cubic feet per second. Despite its age, the dam is well-maintained and has a low hazard potential, with a satisfactory condition assessment as of the last inspection in February 2019.
The dam on Hodgson-Harris is regulated by the state of Colorado, with the Department of Water Resources overseeing permitting, inspection, and enforcement activities. The structure plays a crucial role in managing surface water resources, with a normal storage capacity of 112 acre-feet and serving as a habitat for fish and wildlife in the area. The risk assessment for Hodgson-Harris indicates a moderate risk level, emphasizing the importance of continued monitoring and risk management measures to ensure the safety and functionality of the dam for the surrounding community.
Situated on the Rock Creek-TR stream, Hodgson-Harris contributes to the overall water management infrastructure in the region, providing essential resources for both ecological and recreational purposes. With its historical significance and ongoing regulatory oversight, Hodgson-Harris remains a vital component of the water resource landscape in Boulder, Colorado, highlighting the intersection of water conservation, climate resilience, and environmental stewardship in the area.
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 Hodgson-Harris
Where does the data for Hodgson-Harris 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.
