The Salmon Watershed
Introduction

Map by Dugald Carmichael
Headwaters means the places where a river starts. First it is a trickle that soon further downhill will be joined by another trickle to form a flow that is hard to jump across. As other sources add their flows the stream becomes a substantial creek. Creeks flow together and a river is formed.
The beginning trickle of one watershed is likely to be very close to a beginning trickle that flows the other way into a neigbouring watershed. The land that separates them is called ‘the height of land’ and it is mapped as the watershed boundary.

This trickle is the Headwaters of Beaver Creek and the Salmon River
