Comerio I Dam dam
Comerio I Dam
Comerio I Dam, located in Comerío, Puerto Rico, is a hydroelectric dam on the La Plata River with a primary purpose of generating electricity. Built in 1907, this gravity dam stands at 47 feet tall and has a storage capacity of 500 acre-feet. With a drainage area of 136 square miles and a maximum discharge of 19,970 cubic feet per second, the dam plays a crucial role in water resource management in the region.
Despite its historical significance and important role in providing renewable energy, Comerio I Dam is facing challenges in terms of its condition assessment. The dam has been rated as having a poor condition, with a high hazard potential. The last inspection in September 2019 revealed the need for significant maintenance and repairs to ensure the safety and reliability of the structure. As a result, the risk assessment for the dam is moderate, indicating the importance of proactive risk management measures to mitigate potential hazards.
Given its age and condition, Comerio I Dam serves as a reminder of the ongoing maintenance and investment needed in our water infrastructure to ensure the sustainability and resilience of our water resources in the face of climate change. As a key player in the water resource and climate conversation, enthusiasts should closely monitor the developments and efforts to address the challenges facing this important hydroelectric facility.

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 Comerio I Dam
Where does the data for Comerio I Dam 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.
