Welcome to CSERC's Watershed Game!
A WATERSHED is an area of land that collects water from rain or snow. The water collected in the watershed seeps into the ground or flows downstream into rivers, streams, and lakes.
Here is a picture of a watershed. The purple dashed line marks the boundary of the watershed.
PRECIPITATION is water from rain or snow that falls to the earth and flows into streams.
The HEADWATERS are the places where streams begin.
Small TRIBUTARY streams join to make larger streams. Larger streams join to form rivers.
A FLOODPLAIN is an area that can become flooded when a river or stream overflows.
An ESTUARY is the area where the river meets the ocean. Fresh water from the river and salt water from the ocean mix here.
A RIDGELINE is the top edge of the mountain that divides one watershed from another.
