John Carl Warnecke dam
John Carl Warnecke
John Carl Warnecke is a privately owned Earth dam located in Del Rio Woods, Sonoma, California. Built in 1974, this dam serves primarily for water supply, with a storage capacity of 30 acre-feet. Standing at a height of 32 feet, it spans 238 feet in length and has a hydraulic height of 27.5 feet. The dam is regulated and inspected by the Department of Water Resources for the safety of dams, ensuring its satisfactory condition and low hazard potential.
Situated on the Tr Russian River, John Carl Warnecke plays a crucial role in irrigation and water supply for the surrounding area. Managed by private owners, this dam is subject to state jurisdiction, permitting, inspection, and enforcement. With a drainage area of 0.11 square miles and a surface area of 2 acres, it contributes to the sustainable management of water resources in the region. The dam's location, design, and purpose make it a significant infrastructure for water resource and climate enthusiasts to study and appreciate.
Representing a blend of engineering excellence and environmental stewardship, John Carl Warnecke embodies the intersection of water supply infrastructure and natural conservation efforts. With its historical significance and ongoing role in water management, this dam stands as a testament to responsible resource utilization and the importance of regulatory oversight in ensuring the resilience of critical infrastructure in the face of climate change challenges. For enthusiasts interested in the intricate relationship between water resources, climate dynamics, and infrastructure development, John Carl Warnecke offers a compelling case study worth exploring.

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 John Carl Warnecke
Where does the data for John Carl Warnecke 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.
