Because the Bay is so important to fishing industries and transportation, there are many efforts to regulate and improve the waters of the Chesapeake. The Bay has an average depth of about 21 feet but most of the Bay is shallow. Shipping lanes make use of the deep channels in the bay and many of these are over 100 foot deep.  <ref>http://www.chesapeakebay.net/about.htm</ref> The ports of Baltimore and Norfolk are just two of many important or historical ports found on the Bay.
