Read Dam and Reservoir Conditions and Route a Concern to the Responsible Authority

For active flooding, overtopping, rapid change, structural damage, unusual flow, security concern, or another urgent condition, move to safety and use the current owner/operator, emergency, and dam-safety authority route. Do not enter restricted areas, approach moving water, touch equipment, inspect a structure, or infer failure from this guide.

Record the official dam name and identifier, reservoir, associated structures, generalized location, owner/operator source, access date, and unresolved identity. Treat the National Inventory of Dams as discovery evidence; verify current ownership, operating status, jurisdiction, and contacts through responsible authorities.

Build attributable primary and backup routes for the current owner, on-duty operator, dam-safety regulator, water-control authority, emergency management, law enforcement, environmental authority, Tribal authority, and downstream public-safety coordination. Record duty transfer and acknowledgement rather than assuming a published contact is on duty.

Hazard potential class describes potential consequences under a defined classification system. It does not describe current condition, likelihood of failure, maintenance quality, or safety. Condition and risk conclusions require attributable qualified evaluations under the controlling program.

From a safe and authorized location, record time with offset, generalized location, weather, reservoir and downstream context, photographs, observable seepage, cracking, erosion, debris, unusual sound, vibration, flow, or equipment status, and access limitations. Do not convert an observation into a safety rating, failure mode, cause, or control recommendation.

Record whether a value is gage height, stage, water-surface elevation, storage, inflow, outflow, observed telemetry, field observation, forecast, model output, or reported value. Preserve unit, datum, station, time, provisional status, source, and version. Stage is not interchangeable with elevation unless the datum relationship is explicit.

Restrict precise gate, valve, control-sequence, threshold, vulnerability, instrumentation, communications, access, contact-tree, inundation, downstream critical-asset, and personnel details. A public inventory field does not make a combined owner/operator or emergency record safe to publish.

Record recipient, role, channel, timestamp, acknowledgement, case or log reference, evidence transmitted, instructions received, open owner, and next check. Use the current plan and authority route; do not classify an emergency or direct an operating response.

Link later evaluations to the exact qualified author, organization, evidence version, scope, date, limitations, regulator or owner disposition, and supersession. Inspection complete, maintenance complete, or no alarm does not establish safe condition.

Preserve corrections, supersession, closure owner, unresolved items, and any authority-issued public communication. LakeTech does not activate or terminate an EAP, classify an emergency, issue or lift a warning, order evacuation, or declare a dam safe.
