Blockton Watershed Site V-1 dam
Blockton Watershed Site V-1
Blockton Watershed Site V-1 is a vital water resource located in Taylor, Iowa, managed by the local government and designed by the USDA NRCS. This site serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. The dam, completed in 1966, is an earth structure with a height of 32 feet and a length of 558 feet, providing storage of 124 acre-feet and covering a surface area of 8.3 acres. Despite being classified as having a low hazard potential, it is regulated by the Iowa DNR and undergoes state inspections, permitting, and enforcement to ensure safety and compliance.
Situated on the TR-Platte River, Blockton Watershed Site V-1 plays a crucial role in managing water resources in the region. With a drainage area of 0.22 square miles, this site helps in controlling the flow of water and reducing flood risks in the surrounding area. The dam is equipped with an uncontrolled spillway and is primarily constructed for fire protection and agricultural purposes, reflecting the site's importance for both environmental conservation and community safety.
Although the dam is currently rated as "Not Rated" in terms of condition assessment, it is considered to have moderate risk (3) according to the risk assessment. Despite this, the overall risk management measures and emergency preparedness protocols for the site are not explicitly outlined. With its strategic location and multi-functional capabilities, Blockton Watershed Site V-1 stands as a significant asset in ensuring water security, environmental sustainability, and disaster resilience in the region.
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 Blockton Watershed Site V-1
Where does the data for Blockton Watershed Site V-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.
