What the guide reads first.

Three sources, every time you ask — plus your own logbook.

The day

  • Days of weather leading up to now
  • Wind, sky and air temperature
  • Barometric pressure and its trend
  • Water temperature, live where gauged
  • Sun, moon and feeding periods

The water

  • Acres, average and max depth
  • Contours where surveyed — five states today
  • Boat landings and shore access
  • State survey and stocking history
  • Regulations for that water

The fish

  • What it eats, and what works on it
  • The depth and structure it holds on
  • The hours of the day it feeds
  • How that shifts with season and temp
  • Whether it's stocked there, and how heavily

And your own logbook. Log species, counts, bait and hours. Over a season the guide works from how you fish, not anglers in general.
