Bass anglers organizing to chart Lake Spokane, update maps

SonarChart technology integrates sonar logs shared by individual users with existing data to update maps to show the ever changing conditions of sea, lake and river bottoms.

FISHING -- Navionics and members of the Spokane Bass Club are teaming on Saturday to create a better HD bathymetric (topographical) map of Lake Spokane/Long Lake.

  • Anglers who have boats outfitted with sonar units can join the effort by emailing Tyler Brinks, tylerbrinks@yahoo.com. The group will meet at the Nine Mile Recreation Area launch (Discover Pass required) at 8 a.m. and work until noon.

The process involves idling and surveying the lake using our GPS/fish finders and then uploading to Navionics who will update their SonarCharts™maps within a week.

Learn how to record sonar logs using your Humminbird, Lowrance, Raymarine, Simrad, B&G and Garmin equipment.

Save to any card, upload, and see results in about one week.
