The geographic pattern of smolt out-migration timing was more pronounced than the researchers expected. You're particularly interested in dams that are symbolized as having no fishway (red points), but you'll examine the imagery surrounding all the dam sites for a clear assessment of fish passage upstream. Then, you'll use the result to summarize a stream dataset to determine the potential amount of accessible salmon spawning habitat. Both dams are on the same river, so they will have similar upstream drainage areas. A study suggests that Pacific salmon are born with an in-built "magnetic map" that helps them to migrate over thousands of kilometres. The annual salmon migration occurs in the late summer and early fall and is a popular tourist attraction for both anglers and tourists, typically attracting thousands of visitors annually. In the Label Features pane, for Text, choose Dam ID. Home Conservation groups, Greenland fishermen agree on 12-year salmon moratorium salmon-migration-map.
