Joder dam
Joder
Joder, located in Boulder, Colorado, is a crucial water resource managed by a public utility for irrigation purposes. Completed in 1962, this Earth dam stands at a height of 36 feet and has a storage capacity of 140 acre-feet, serving the local community's water supply needs. The dam spans 1100 feet and is regulated by the Colorado Department of Water Resources, ensuring its safety and compliance with state regulations.
Despite its low hazard potential and satisfactory condition assessment, Joder poses a moderate risk with a risk assessment rating of 3. Regular inspections every six years and emergency preparedness protocols contribute to its overall safety and risk management. The dam's spillway type is uncontrolled, with a width of 40 feet, allowing for the controlled release of excess water. With a maximum discharge capacity of 1380 cubic feet per second, Joder plays a crucial role in managing water flow in the Dry Creek-TR river system, contributing to the overall water resource management in the region.
As a focal point for water supply and irrigation in the area, Joder serves as a vital infrastructure for sustainable water management in Boulder, Colorado. With its strategic location and reliable performance, this Earth dam continues to play a crucial role in ensuring water security and resource sustainability for the community. Its moderate risk assessment underscores the importance of ongoing monitoring and maintenance to uphold its integrity and functionality for the future.
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 Joder
Where does the data for Joder 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.
