About this water

The Coldwater is a small, pretty Nicola-valley freestone near Merritt with wild rainbows in clear riffles and undercut-bank pockets. It's accessible small-stream fishing, best once spring runoff drops and through the cooler windows of the season — a pleasant, honest interior rainbow creek.

Under the surface

The Coldwater is a small, pretty Nicola-valley freestone near Merritt holding wild rainbow trout — clear riffles, pockets and undercut banks in open interior country. Intimate, accessible small-stream fishing for honest wild rainbows, at its best once the spring runoff drops and through the cooler parts of the season.

Wading: Flashy snowmelt, slick cobble, warm low water in high summer
