Gs Dd No A-87 dam
Gs Dd No A-87
Located in Jackson County, Kansas, Gs Dd No A-87 is an earth dam constructed in 1985 by Speaker & King for flood risk reduction along the Straight Creek-TR. With a height of 27 feet and a length of 590 feet, this dam has a capacity of 87 acre-feet, serving as a crucial structure for debris control and flood risk reduction purposes. Despite its low hazard potential, the dam remains ungraded in terms of condition assessment, with no recent inspection data available.
The dam's primary purpose is flood risk reduction, with a normal storage capacity of 19 acre-feet and a maximum discharge capacity of 909 cfs. The spillway, with a width of 53 feet, is uncontrolled, and there are no outlet gates or associated structures. The risk assessment for Gs Dd No A-87 is moderate, with no specific risk management measures or emergency action plans currently in place. In terms of jurisdiction and regulation, the dam is not under state authority, with no state permitting, inspection, or enforcement requirements.
Overall, Gs Dd No A-87 plays a vital role in managing flood risk in the region, although there are areas for improvement in terms of monitoring and emergency preparedness. As a local government-owned structure, it is essential for stakeholders to prioritize regular inspections, condition assessments, and the development of emergency action plans to ensure the safety and effectiveness of this earth dam in the face of changing climate conditions and water resource management challenges.
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 Gs Dd No A-87
Where does the data for Gs Dd No A-87 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.
