250-acre lake near Bend. The lake tops out around 9 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 251 acres, worked by 5.6 miles of shoreline. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage.
