lake Hamilton garmin map

does anyone have a map of lake Hamilton they would share? garmin doesnt have a map of lake Hamilton and there was very little on the community deal.

See if this helps. I use this site at home while planning trips. https://webapp.navionics.com/#boating@12&key=k%7BdqEdvdwP

Your best bet would probably be the Navionics phone or tablet app if needed while on the water, since Garmin will not allow users to use other mapping options in their cahrtplotters. If not on the water and just to check out before heading out, the webapp above is a great option. Both offer the most updated mapping from Navionics with the Sonar Charts feature.
