Green Point-Upper (No. 2) dam
Green Point-Upper (No. 2)
Green Point-Upper (No. 2) is a vital earth dam located on Green Point Creek in Hood River, Oregon, completed in 1937 primarily for irrigation purposes. With a dam height of 31 feet and a storage capacity of 900 acre-feet, this structure plays a crucial role in managing water resources in the region. The dam's significant hazard potential and moderate risk assessment highlight the importance of regular inspections and maintenance to ensure its safety and functionality.
Owned by the local government and regulated by the Oregon Water Resources Department, Green Point-Upper (No. 2) is subject to state jurisdiction, permitting, inspection, and enforcement. The dam's uncontrolled spillway and surface area of 43.6 acres contribute to its hydraulic and structural height of 29 and 31 feet, respectively. The dam's location in the Portland District underlines its importance in serving the surrounding agricultural community by providing essential irrigation water and flood protection.
Despite being not rated for its condition assessment, Green Point-Upper (No. 2) remains a key infrastructure for water management in the area. With a drainage area of 0.85 square miles and a maximum discharge of 211 cubic feet per second, this dam reflects the intersection of water resource management and climate adaptation. As climate change continues to impact water availability and extreme weather events, ensuring the safety and efficiency of dams like Green Point-Upper (No. 2) is crucial for sustainable water management practices and community resilience.
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 Green Point-Upper (No. 2)
Where does the data for Green Point-Upper (No. 2) 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.
