AccessPrearranged guided access only after confirming reservoir permission, boat support, water level, weather and local emergency plan. No boat relationship is created.
ExperienceAltitude Diver training strongly recommended; experienced certified divers with altitude-adjusted planning and professional supervision.
Maximum depthMaximum approximately 15 m, but altitude-equivalent depth and decompression exposure must be calculated correctly.
Best seasonPotentially year-round by advance arrangement; water level, highland weather and operator availability control access.
VisibilityVariable with swell, plankton, current, season and weather; confirm same-day visibility locally.

Automatically checked
No recent diver reports from the past 14 days

A report that passes the automatic checks will appear here with the dive date, diver’s display name, and temperatures at each depth.

Reports are automatically checked for plausible dates, depths, and temperatures. They are observations, not forecasts; confirm conditions before diving.

Before you arrive

Access notes

Prearranged guided access only after confirming reservoir permission, boat support, water level, weather and local emergency plan. No boat relationship is created. Book with a qualified local professional and reconfirm certification, route, depth, gas, entry/exit, permissions, wildlife rules and emergency plan. The displayed coordinate is deliberately approximate and must never be used as an entry point, mooring, structure position or navigation waypoint.

Plan within your training

Conditions and hazards

3,300 m altitude, altitude decompression error, cold freshwater, reduced surface oxygen, weather, boat operations, low visibility, aquaculture activity and remote emergency response.

At the site

Facilities and support

Current southern Peru operators advertise guided shore/boat diving, rentals, air fills, training and equipment support; confirm oxygen, communications and remote-response arrangements.

Independent resource notice

This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
