There is a good site in British Columbia that also gives you depth information for lakes. Its is called Fish Wizard and is located at [url=http://maps.gov.bc.ca/imf406/imf.jsp?site=libc_awiz:2825c]http://maps.gov.bc.ca/imf406/imf.jsp?site=libc_awiz[/url:2825c]

In addition it lists all the species found in a lake and provides stocking information. Well worth checking out if you are lake fishing in BC.
