Both join to become rivers that flow intoMap Keythe estuary.Low (below 10 ppt.)Because the Chesapeake Bay is partly enclosed byMedium (10 – 20 ppt.)land, fresh water and salt water meet and mix there.High (20 – 30 ppt.)Fresh water in the Bay come from rivers, so the wateris less salty at the mouths of rivers. Salt water fromthe Atlantic Ocean flows into the Bay at its opening insouthern Virginia so the Bay is saltier farther south.What is a watershed?The Chesapeake Bay WatershedThe Chesapeake Bay is enclosed by Delaware andthe eastern parts of Maryland and Virginia.

Freshwater runoffcarries these nutrients from the land. Any body of waterwith high levels of plant nutrients has high numbers ofplants and algae. Since plants are the start of the foodchain for all the animals that live in the water, wherethere are lots of plants, there are many animals.In part because of the largefood supply, estuaries areparticularly good placesfor many young animalsWhat does the estuary provide to animals that inhabit it?to get their start. Estuariesare nurseries for manyspecies of fish, shrimp andother animals that live inthe ocean as adults. Fishlike shad, herring and striped bass (rockfish) migrate fromthe ocean through the estuary and into rivers to spawn,or lay their eggs. The eggs develop into larval (baby) fish,which move down into the estuary to feed and growbefore leaving to live in the open sea.4

The Chesapeake Bayprovides 50 percent of the total blue crab harvestin the United States. Striped bass (also called rockfishin the Chesapeake region) are the one of the mostfamous fish found in the Bay. They are important bothas sportfish and for commercial catch.How can your actions in your neighborhood or schoolaffect our food supply?About half of the fish and other sea animals we eatdepend on an estuary during some part of their life.When we damage an estuary, we not only hurt theplants and animals that live there, we also destroypart of our food supply.Do organisms get dissolved oxygen from the O2 inWater QualityAll animals need oxygen forsurvival.
