Shavano Valley #2 - Sv-2 dam
Shavano Valley #2 - Sv-2
Shavano Valley #2 (Sv-2) is a public utility dam located in Olathe, Colorado, within Montrose County. Built in 1996 by the USDA NRCS, this earth dam stands at a height of 38 feet and serves the primary purpose of flood risk reduction along the Uncompahgre River. With a storage capacity of 414 acre-feet, the dam covers a surface area of 21 acres and has a drainage area of 3 square miles.
Despite its satisfactory condition assessment as of October 2019, Shavano Valley #2 poses a high hazard potential, indicating the need for regular inspections and risk management measures. The dam's uncontrolled outlet gates, coupled with its high risk assessment, highlight the importance of emergency preparedness and adherence to safety guidelines in case of potential inundation events. With a high-risk rating of 2, stakeholders must remain vigilant in monitoring the dam's structural integrity and implementing necessary precautions to mitigate potential hazards.
Situated in the Albuquerque District, Shavano Valley #2 stands as a crucial infrastructure for flood risk reduction in the region. With its proximity to the Uncompahgre River and its vital role in safeguarding the surrounding area, this dam serves as a testament to the collaborative efforts of the Natural Resources Conservation Service and state regulatory agencies in ensuring the safety and resilience of water resources in Colorado.

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 Shavano Valley #2 - Sv-2
Where does the data for Shavano Valley #2 - Sv-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 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.
