Flatton Lake, Montana: Fishing Spots and Seasons

• Overview

  The Glacier County entry here is Flatton Lake, in Montana. The bank is 5,656 feet above sea level. Surface area runs to about 22 acres — small enough to read in one session. The town to know is North Browning, 25 miles out. Browning is 26 miles and South Browning 26 miles. Close by you have: Lower Saint Mary Lake about 1.7 miles, Lake Sherburne after 5.7 miles, Swiftcurrent Ridge Lake about 6.7 miles, Saint Mary Lake after 7.7 miles and Duck Lake about 7.9 miles. No border sits close enough to matter.

• Where to Fish on Flatton Lake

  Nothing we hold settles how deep this runs. This is a lake, so the margins and the first drop matter most. Bays and points beat straight shoreline every time on water like this. Survey and observation records for Glacier County include brook trout, northern pike, longnose sucker and yellow perch. Take it as the county picture rather than a promise for this water. Take Flatton Lake a stretch at a time.

• Seasonal Patterns

  August runs about 58°F on average, January about 19°F. Fishing here follows the temperature more than the calendar. Winter locks it down, and late April brings it back. Climate averages put the opening at about late April and the closing near late November. The strong weeks are the first after break-up and the last before the freeze. Plan around that when you fish Flatton Lake.

• Tackle & Baits

  No public source sets out the position on this bank. Public data shows nothing built here, so treat the whole approach as informal. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Some banks are open only from a marked point. Close seasons apply to some species and not others. Lower Saint Mary Lake at 1.7 miles is the sensible second choice. Treat Flatton Lake as unsettled until someone local tells you otherwise.
