About this dam

Darrington Dam No 1

Darrington Dam No 1 is a privately owned earth dam located in Worth, Missouri, along the TR-JAY Creek. Completed in 1991, this dam serves multiple purposes including grade stabilization, fire protection, and as a stock or small fish pond. With a height of 26 feet and a length of 270 feet, the dam has a storage capacity of 29 acre-feet and covers a surface area of 5 acres.

Despite being privately owned, Darrington Dam No 1 is not regulated or inspected by the state of Missouri. The dam has a low hazard potential and has not been rated for its condition. With a moderate risk assessment score of 3, there are no emergency action plans in place or updated contact information for emergencies. The dam features an uncontrolled spillway with a width of 10 feet and no outlet gates.

Water resource and climate enthusiasts interested in Darrington Dam No 1 will find it to be a noteworthy structure for its multiple purposes and the lack of state regulation. The dam's location in Worth, Missouri, and its design as an earth dam with a stone core make it a unique feature along TR-JAY Creek. Despite its low hazard potential, the dam's moderate risk assessment score highlights the need for improved emergency preparedness and risk management measures in the event of any potential issues.

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.

FAQ

About Darrington Dam No 1

Where does the data for Darrington Dam No 1 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.
