Lake Aggravation dam
Lake Aggravation
Lake Aggravation, located in Morse Mill, Missouri, is a private recreational reservoir built in 1960 with an earth dam type and a height of 30 feet. The dam holds a storage capacity of 225 acre-feet, with a normal storage level of 115 acre-feet and a surface area of 14 acres. Fed by Tyrey Creek and serving as a popular spot for water enthusiasts, the reservoir poses a high hazard potential but has not been rated for its condition.
Despite being privately owned and not regulated by the state, Lake Aggravation remains a key destination for recreational activities such as fishing, boating, and swimming. With its picturesque setting in Franklin County, this reservoir offers a tranquil escape for nature lovers and climate enthusiasts alike. While lacking certain safety assessments and emergency preparedness measures, the reservoir continues to attract visitors seeking a peaceful retreat in the heart of Missouri's natural beauty.
As climate change threatens water resources worldwide, the importance of monitoring and maintaining reservoirs like Lake Aggravation becomes increasingly crucial. With its potential for hazard and the need for updated risk assessment and emergency plans, this reservoir serves as a reminder of the ongoing challenges in managing water sources in the face of a changing climate. By raising awareness and investing in sustainable water management practices, Lake Aggravation can continue to provide a safe and enjoyable environment for outdoor enthusiasts while adapting to the evolving climate conditions.

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 Lake Aggravation
Where does the data for Lake Aggravation 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.
