Lake Tekapo (Takapō) lies at the northern edge of the Mackenzie Basin in the South Island, with the township of Lake Tekapo on its southern shore and the Southern Alps at its head. It is a long glacial lake, milky turquoise from fine rock flour carried down by its glacier-fed rivers, and it is cold all year.
The colour draws the crowds. For a packrafter, the wind and the temperature are what shape the day.
Glacial water
The lake is fed by rivers draining the glaciers of the Southern Alps, chiefly the Godley and the Macaulay at its head. That water is cold even in midsummer, and the rock flour that gives it colour also means you cannot see far below the surface.
Treat a swim here as a real risk, not an inconvenience. Dress for immersion, not for the air temperature on the beach.
The Mackenzie wind
The Mackenzie Basin is open, high country, and there is little to stop the wind. Northwesterlies come off the Alps, and on a big lake with a long fetch they build steep waves quickly. Southerly changes can swing in and turn a calm lake rough.
Most paddlers here keep to early mornings and the shoreline. Watch the head of the lake: cloud building over the Alps and a darkening line on the water are your cue to head in.
The township shore and beyond
The lakefront at the township, near the outlet and the Church of the Good Shepherd, is the easy place to start. You can launch from the shingle, paddle along the shore and be back within minutes if the wind comes up.
A gravel road follows the eastern shore towards the head of the lake, giving access to other beaches. It is a long way from help once you leave the township. Check access and conditions with DOC, Environment Canterbury and the Mackenzie District Council.
A managed lake
Tekapo is part of the Waitaki hydro scheme, and its level is controlled at the outlet. Lake levels rise and fall over the year, which moves the shoreline and exposes or covers beaches and shallows.
The river below the outlet is controlled too, and flows can change. Do not paddle near the control structure or the outlet.
Lake Alexandrina
Just west of Tekapo, the much smaller Lake Alexandrina is a good alternative when the big lake is rough. It is shallower and more sheltered, and popular with anglers. Check any local rules on craft before you launch.
Practical notes
The basin sits within the Aoraki Mackenzie International Dark Sky Reserve, so a clear evening by the lake is worth staying up for. Nights are cold even in summer.
Check, Clean, Dry your gear between waterways. Sun is strong at altitude, and shade on the water is scarce.
Wear a buoyancy vest, tell someone your plan, and set a time to call when you are off the water.
Where a Seeka fits
A still morning along the township shore, or a sheltered paddle on Lake Alexandrina, is good Seeka water. A long crossing of the main lake in a building nor’wester is not what a Seeka is built for.
