Perry Gulch dam
Perry Gulch
Perry Gulch, located in Mendocino County, California, is a privately owned Earth-type dam completed in 1980 for the primary purpose of water supply. The dam stands at a height of 37 feet with a hydraulic height of 33 feet, providing a storage capacity of 33 acre-feet. The reservoir covers a surface area of 2 acres and serves irrigation and water supply needs in the area.
Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Perry Gulch Dam is regulated, inspected, and enforced by the state authorities to ensure its safety and compliance with regulations. The dam has a low hazard potential and is assessed to be in satisfactory condition. Despite its modest size, the dam plays a crucial role in water resource management in the region, contributing to the resilience of the local water supply system.
The dam's location in the Perry Gulch area near Navarro, California, underscores its importance in harnessing and storing water resources for agricultural and domestic use. With a focus on water supply, Perry Gulch represents a vital infrastructure piece in the region's efforts to sustainably manage water resources amidst changing climatic conditions and growing water demands. As a key player in the state's water security framework, Perry Gulch Dam stands as a testament to the ongoing efforts to ensure reliable water access in the face of climate challenges.

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 Perry Gulch
Where does the data for Perry Gulch 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.
