About this dam

Roatcap Wash Watershed Rw-1

Roatcap Wash Watershed Rw-1, located in Montrose, Colorado, is a critical water resource managed by USDA NRCS with a primary purpose of flood risk reduction. The earth dam, standing at 48 feet tall with a hydraulic height of 33 feet, was constructed in 1964 to protect the surrounding area from potential flooding. With a normal storage capacity of 790 acre-feet and a maximum discharge of 1530 cubic feet per second, this dam plays a vital role in managing water flow in the region.

The dam's spillway type is uncontrolled, with a width of 73 feet, and it is equipped with slide gates and uncontrolled outlets. Despite being classified as having a high hazard potential, the condition assessment in 2019 was deemed satisfactory. Regular inspections and maintenance ensure the dam's structural integrity and functionality are upheld. The risk assessment for Roatcap Wash Watershed Rw-1 is moderate, indicating a level 3 risk, but with proper risk management measures in place, the community's safety and water resources are well-protected.

Overall, Roatcap Wash Watershed Rw-1 serves as a crucial infrastructure for water management in the area, contributing to flood risk reduction and ensuring the safety of residents in Montrose, Colorado. With its strategic location along the Uncompahgre River, this dam plays a key role in maintaining water flow and mitigating potential hazards. Through ongoing monitoring and upkeep, Roatcap Wash Watershed Rw-1 continues to be a reliable resource in safeguarding the environment and local communities from the impacts of extreme weather events and flooding.

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.

FAQ

About Roatcap Wash Watershed Rw-1

Where does the data for Roatcap Wash Watershed Rw-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 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.
