Goodhart Canyon Detention Basin dam
Goodhart Canyon Detention Basin
Goodhart Canyon Detention Basin, located in Hemet, California, serves as a crucial flood risk reduction infrastructure along the Goodhart Canyon stream. Completed in 1999, this earth dam stands at a height of 15 feet and has a hydraulic height of 10.8 feet, with a total length of 6,823 feet. It has a storage capacity of 1,026 acre-feet and covers a surface area of 98 acres, providing essential protection to the surrounding area from potential flooding events.
Managed by a public utility agency, the Goodhart Canyon Detention Basin is regulated and inspected by the Department of Water Resources (DWR) under the Safety of Dams program. With a high hazard potential, the dam is assessed to be in satisfactory condition as of September 2017. Regular inspections are conducted to ensure the structural integrity and functionality of the basin, with the last inspection taking place in March 2021. Additionally, emergency action plans are in place to address any potential risks and ensure the safety of the community in case of a flood event.
With its vital role in mitigating flood risks in the region, the Goodhart Canyon Detention Basin stands as a testament to effective water resource management and climate resilience efforts. As climate change continues to impact weather patterns and increase the frequency of extreme events, structures like this detention basin play a crucial role in safeguarding communities and infrastructure from the dangers of flooding. Maintaining and monitoring such infrastructure remains essential to ensure the safety and well-being of the residents in Riverside County, California.

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 Goodhart Canyon Detention Basin
Where does the data for Goodhart Canyon Detention Basin 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 High 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.
