Gobbo #1 dam
Gobbo #1
Located in Mesa, Colorado, Gobbo #1 is a privately-owned earth dam with a primary purpose of irrigation on Johnson Creek. Completed in 1973, this structure stands at 33 feet tall with a hydraulic height of 34 feet and a structural height of 44 feet, providing a storage capacity of 246 acre-feet. With a surface area of 13 acres and a maximum discharge of 137 cubic feet per second, Gobbo #1 serves multiple purposes including fire protection, stock watering, and small fish pond maintenance.
Despite being regulated by the Colorado Department of Water Resources, Gobbo #1 poses a significant hazard potential and has a fair condition assessment as of the last inspection in July 2020. The dam features an uncontrolled spillway and outlet gates comprising of slide gates and uncontrolled flow mechanisms. While the risk assessment indicates a moderate level of risk, no emergency action plan (EAP) is currently in place, raising concerns about preparedness in the event of a dam failure.
Given its critical role in irrigation and water supply in the region, stakeholders and water resource enthusiasts should closely monitor the maintenance and management of Gobbo #1 to ensure the safety and sustainability of this vital infrastructure in the face of changing climate patterns and increased water demand.
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 Gobbo #1
Where does the data for Gobbo #1 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 Significant 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.
