Fishing Log Program

Volunteer anglers belong to an exclusive club of individuals who keep diaries of their angling experiences for Montana Fish, Wildlife & Parks. The value of this program dates back to the late 1950s when fishing log data provided the basis for many of the lake and stream water quality classifications required by the 1955 Water Pollution Act. If log holders reported catching trout, the waterbody was classified as suitable for salmonids. Additionally the logbook of a Pennsylvania angler helped fisheries managers deduce that whirling disease may have first shown up in the Madison River as early as 1987.

Today, over 900 anglers are enrolled in the Fishing Log Program and have volunteered to record their fishing activities in a log issued by Montana Fish, Wildlife & Parks. Locations fished, species and number caught, date and miscellaneous information are recorded. An angler can record a "bragging" size fish if they feel that the fish they caught was of unusually large size for the water they were fishing. Once a year, FWP recalls the logs to record and process the data that the anglers have collected. At this time, the logholder will receive a summary of the previous year's data and a fish log decal when the logbook is returned. Participants will also receive a copy of the Fishing Newsletter mailed out in the New Year. The information gathered from the logs is valuable for the management of our fisheries resources.
