Swimming in the rain

As I swam across the Secret Lake small raindrops bounced on the surface, like delicate pin pricks. The water was dark and peaty, and colder than usual. It took my eyes a while to get used to the underwater blackness, but eventually I started to make out the silty bottom and clumps of weeds, occasionally punctuated with a large granite boulder. This place is an oasis of silky calm.
