Map Hayden Lake during Community Lake Mapping Days.

Register here for the
2022 Hayden Lake “Gettin’ to the Bottom of It”
Community Lake Mapping Days!

Mapping Days: April 18-22
Training: April 14, 6:00 p.m. at Marks Marine
Catch a spring day on the water,  and be a part of an unprecedented community effort to map all of Hayden Lake. 

How it works: Interested equipment owners* register here or in person at Mark’s Marine. At the April 11 training, each will be assigned a sector and issued a Micro SC card pre-loaded with a navigation trail. Between the dates of April 18 and April 22, volunteers will survey along their assigned trail, then submit their data cards for uploading to C-MAP’s BioBase.

Participant benefits include:

  • Get the best fishing contour map on the face of the earth – data will go to the latest C-MAP cartography and Genesis SocialMap available at genesismaps.com/socialmap and the C-MAP app.
  • Receive free, detailed, unencrypted bottom hardness and spring-vegetation charts.
  • Contribute valuable data for the ongoing management and protection of the lake, i.e. weed management planning, water quality tracking, community education, and more.

* Participants must provide their own boat, Lowrance, and 200 kHz or structure transducer.

Marks Marine and Hayden Lake Watershed Improvement District sponsor the Hayden Lake Map Days.
