The Thames has fresh water from its source in the Cotswolds, as nearly all rivers have fresh water from their sources.
Generally, beaches found on oceans and their estuaries will be salt water, and the remainder of the beaches found upstream will be fresh.
Salmon lay there fish upstream so fresh water fish wont eat their eggs. Also because, salmon grow up in salt water environment.
Rivers usually contain fresh water. Fresh water usually contains fish which can be grilled on a fire and eaten by a human. You can usually drink this water without boiling it as well. Rivers also show a human that following it downstream will result in the finding of a larger body of water, and upstream is elevated.
The coastal ocean is the narrow strip of ocean from the outer edge of the continental shelf to the greatest distance upstream that salt water mixes with the fresh water of a river flowing into the ocean.
Water always flows down a river, so upstream is the opposite direction from the direction in which the water flows.
the Great Lakes are fresh water.( the largest fresh water lakes in the world.)
