Two lakes. One frame. One restless, one perfectly still.
This is Mirror Lake (the small one, tucked behind the trees) and Kootenay Lake — taken from the air just south of Kaslo. They sit side by side, separated by a narrow strip of land, and yet they couldn’t be more different in character.
Mirror Lake got its name honestly. Sheltered by the surrounding mountains, the wind rarely touches its surface — leaving the water smooth and reflective. Early records show it was once called “Little Lake,” before it gradually became known as Mirror Lake.
Beside it, Kootenay Lake stretches more than a hundred kilometres through the Selkirk and Purcell Mountains — one of the longest lakes in British Columbia.
Mirror Lake has its own quiet history. It hosted the first curling bonspiel in the Kootenays in March 1896, back when the surface froze hard and Kaslo’s miners and merchants came down to play on the ice. Some of the earliest hockey in the Kaslo area was played here, before there was a proper rink anywhere in the region. Between 1896 and 1900, several of the paddlewheel steamboats that worked Kootenay Lake — the International, the Kaslo, the Argenta — were built right on these shores.
And there’s the story of the post office. Opened in 1909, closed in 1970, and about the size of a toolshed. Local lore says it was once featured in Ripley’s Believe It or Not as the world’s smallest. The original building still exists — it now sits next to the SS Moyie in Kaslo.
Two lakes side by side. One that moves, one that holds still. There’s something to that.
