How streams move water
Channels, gradient, riffles and pools, and how a stream's shape changes from headwaters to mouth.
Freshwater · Streams · Watersheds
A plain-language reference on the way freshwater streams carry water downhill, how riparian edges hold a creek together, and which everyday habits keep that water clean. Written for residents, students, and shoreline volunteers across Canadian watersheds.
Core topics
Each reference page stays narrow and practical, with Canadian examples and links to public agencies.
Channels, gradient, riffles and pools, and how a stream's shape changes from headwaters to mouth.
The band of plants and roots along a creek, and why that green edge controls erosion, shade, and habitat.
Yard, road, and shoreline habits that reduce runoff and keep sediment and nutrients out of the water.
What a watershed is
A watershed is the area of land that drains to a single stream, river, or lake. Ridgelines mark its edges; rain and snowmelt inside those edges move downhill through soil and small channels until they join larger water. Because land and water are linked this way, what happens on a slope eventually reaches the creek below it.
Canada holds a large share of the world's surface freshwater, and most of it travels through countless small streams before reaching major rivers and the ocean. Those small channels are where water quality is shaped first.
