Best of luck.
Lake Havasu City is about 20 minutes from one side of town to another. We have 3 zip codes: 86406 is South side, 86404 is North side and what most people think of town is somehere in 86403. If you go on my website you can order a map that I can send to you and help you get a better idea of our layout.
It's a fairly compact town so nothing is more than a few minutes from the lake.
Are you planning a visit sometime in the near future?
You can go to my site and get a lot of good information about Havasu and the surrounding area.

If so, the launch ramp is between 3-5 miles. The city itself is about 12 miles wide with the lake on the west side.
Hope this helps,
