Grove Creek #2 dam
Grove Creek #2
Grove Creek #2, also known as Emerson & Libby #2, is a private earth dam located in Mesa County, Colorado, specifically in the city of Collbran. Completed in 1911 for irrigation purposes, this historic structure stands at 16 feet tall and spans 755 feet in length. With a maximum storage capacity of 364 acre-feet and a normal storage of 76 acre-feet, this dam plays a crucial role in water resource management along Grove Creek.
Despite its age, Grove Creek #2 is in fair condition according to a 2015 assessment, with a low hazard potential. The dam underwent modifications in 1956 to enhance its hydraulic, mechanical, and structural features. It has a slide (sluice gate) outlet gate and no spillway, with a maximum discharge of 33,865 cubic feet per second. The risk assessment for this dam is rated as high (2), highlighting the importance of ongoing monitoring and maintenance to ensure its continued safety and effectiveness in water management for the surrounding area.
In the picturesque setting of Grove Creek, this private earth dam stands as a testament to early 20th-century water infrastructure development in Colorado. With its rich history and vital role in irrigation, Grove Creek #2 serves as a reminder of the enduring importance of sustainable water resource management practices in the face of changing climate conditions.
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 Grove Creek #2
Where does the data for Grove Creek #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 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.
