Calvert Mine Spc-31 Dam dam
Calvert Mine Spc-31 Dam
Calvert Mine Spc-31 Dam, located in Robertson County, Texas, is a privately owned structure designed by Godsey Engineering and completed in 1996. This Earth-type dam stands at a height of 18 feet and has a length of 2200 feet, with a storage capacity of 160 acre-feet. The dam serves a primary purpose of "Other", with a spillway width of 40 feet and a maximum discharge capacity of 696 cubic feet per second.
Although the dam is not state-regulated, it is subject to state permitting and inspection. The dam's hazard potential is listed as "Not Available", with a risk assessment rating of "Moderate (3)". The condition of the dam is currently not rated, and it does not have an emergency action plan in place. Despite these factors, the dam plays a crucial role in managing water resources in the area, particularly in relation to the TR-BIG WILLOW CREEK river or stream.
Overall, Calvert Mine Spc-31 Dam is a key infrastructure component in the region, providing essential water storage and management capabilities. Its design, construction, and operational aspects make it a vital asset for water resource and climate enthusiasts to monitor and evaluate for its role in maintaining water security and mitigating potential risks associated with flooding or dam failure.

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 Calvert Mine Spc-31 Dam
Where does the data for Calvert Mine Spc-31 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 Not Available 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.
