Footnotes ...

<1>If you're interested in how the shape of Illinois' counties, including Ogle, have changed over time, we recommend the Atlas of Historical County Boundaries.
<2>The pronunciation we've provided is our attempt to give a phonetic pronunciation for Watertown. While it might not be exactly right, hopefully it will be close. If we have it wrong or there's a better way to pronounce the name, please contact us through our Feedback Page.
<3>The elevation is an estimate for the area around Watertown - it will be higher in some places and lower in others.
<4>When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 815 code has been Overlayed with the 779 area code. New phone numbers in the Watertown area will be assigned with one of these codes: 815 or 779. As a result, placing a call in the Watertown area will require 10-digit dialing (where you enter both the area code and then the phone number).
<5>While we're fans and frequent users of TripAdvisor, you should know that we're also members of the TripAdvisor affiliate program.
<6>The location has been supplied by the Geographic Names Information System - which is maintained by the U.S. Geological Survey (USGS). While these values should be definitive, we found that accuracy can vary and you should double-check the location if accuracy is required.
