downstream

Everyday

1. Downstream means in the direction a river or stream flows, towards the sea. tree →
2. Downstream describes a place further along a river in that direction. tree →

In the lessons

In geography and science, rivers flow downstream from the source in the hills to the mouth at the sea; things floating drift downstream. In stories boats and rafts are carried downstream. Phrases: «float downstream», «further downstream», «swim against the current» (upstream).

Examples

• The leaf floated downstream. tree →
• We paddled our canoe downstream. tree →
• The village is a mile downstream from the bridge. tree →
• Rivers get wider as they flow downstream. tree →
• Salmon swim upstream, not downstream, to lay their eggs. tree →
• Pollution upstream can harm fish downstream. tree →
• Never chase a ball that is being carried downstream; the water is stronger than you think. tree →
• Remember, you are upstream and I am downstream." tree →

Note

One word. Opposite: «upstream». In maths problems a boat going downstream goes faster because the current adds to its speed; going upstream the current takes speed away. Safety: rivers are dangerous; stay out of fast water.
