Lost Trails Estates Dam dam
Lost Trails Estates Dam
Lost Trails Estates Dam, located in Highridge, Missouri, is a privately-owned structure that serves primarily for recreational purposes. Completed in 1978, this earth dam stands at a height of 43 feet and spans 420 feet in length. It holds a storage capacity of 104 acre-feet and covers a surface area of 6 acres, with a drainage area of 38 square miles. The dam is regulated by the DAM AND RESERVOIR SAFETY PROG in Missouri, ensuring regular inspections and enforcement of safety measures.
With a high hazard potential and a satisfactory condition assessment, Lost Trails Estates Dam poses moderate risks that are actively managed to maintain safety standards. The dam features an uncontrolled spillway with a width of 10 feet, and outlet gates are not present. Despite being in a state-regulated jurisdiction, the dam has not undergone modifications in recent years. The last inspection in March 2017 indicated compliance with safety standards, with an inspection frequency of every 5 years.
Lost Trails Estates Dam provides a vital recreational resource in the area, offering opportunities for outdoor activities and water-based recreation. Located near the TRIB TO ROCK CREEK, this dam contributes to the local ecosystem while also serving as a potential emergency contact point in case of any unforeseen events. The presence of Lost Trails Estates Dam highlights the importance of proper dam management and maintenance to ensure the safety of surrounding communities and water resources in the region.

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 Lost Trails Estates Dam
Where does the data for Lost Trails Estates 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 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.
