Henry Jr. dam
Henry Jr.
Henry Jr. is a privately owned dam located in Barrett Junction, California, along the Skye Valley river. Completed in 1929, this arch dam stands at a height of 33 feet and has a storage capacity of 196 acre-feet. Its primary purpose is for water supply, serving irrigation, recreation, and other water-related needs in the area. The dam is regulated by the California Department of Water Resources (DWR) and undergoes regular inspections to ensure its safety and functionality.
With a low hazard potential and a satisfactory condition assessment as of September 2017, Henry Jr. provides a vital water resource for the San Diego County area. The dam has a drainage area of 9.3 square miles and a surface area of 22 acres, contributing to the local ecosystem and water management infrastructure. Its strategic location and design make it a key asset in the region's water supply network, ensuring reliable access to water for various purposes.
Managed by private owners, Henry Jr. plays a crucial role in water management and conservation efforts in the region. Its historical significance, combined with its modern functionality, highlights the importance of sustainable water resource management in the face of changing climate patterns. Enthusiasts and experts in water resources and climate science can appreciate the role that dams like Henry Jr. play in ensuring water security and resilience in California's dynamic 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 Henry Jr.
Where does the data for Henry Jr. 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.
