In mid-August, two springs appeared on the bed of Kokanee Creek (at ~400 metres from the mouth). They persisted until early September, when they disappeared. In mid-October, one spring reappeared.
Visually, the springs were a churning mass of a lighter shade of sand upwelling from below which then spreading sideways.
On September 1st, Gary Munro waded out and took temperature measurements. Thrusting the thermometer deep into the upwelling fluid, he got a reading of 7 °C. At the time the water flowing in the creek was 11 °C.
This suggests that the source of the spring water was not elsewhere on the creek, but possibly ground water from off the mountainside. But, who knows?
