Mc Masters Subwatershed 3907 dam
Mc Masters Subwatershed 3907
Mc Masters Subwatershed 3907 is a vital water resource located in Monona, Iowa, specifically in the city of TURIN. This subwatershed is regulated by the Iowa Department of Natural Resources and is designed by the USDA NRCS, highlighting the collaboration between local government and federal agencies to ensure proper management and protection of the water resource. The dam in Mc Masters Subwatershed 3907 serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction, making it a crucial element in the local ecosystem.
Constructed in 1955, the Earth-type dam in Mc Masters Subwatershed 3907 has a height of 42 feet and a storage capacity of 127 acre-feet. The dam covers a surface area of 5 acres and drains a watershed area of 0.77 square miles, providing essential water storage and flood control capabilities for the surrounding area. Despite its low hazard potential, the dam's risk assessment is rated as moderate, signaling the need for ongoing risk management measures to ensure the safety and integrity of the structure.
With its strategic location along the TR-LITTLE SIOUX RIVER, Mc Masters Subwatershed 3907 plays a crucial role in water management and conservation efforts in the region. Its association with the Natural Resources Conservation Service and other federal agencies underscores the importance of collaboration in maintaining sustainable water resources for future generations.
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 Mc Masters Subwatershed 3907
Where does the data for Mc Masters Subwatershed 3907 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.
