Montana lakes list, explained
Which lakes earn their own page?
The 240 FWP-mapped lakes with five or more facts of their own; 1,447 more named lakes from the FWP layer appear only on their county pages.
Which reservoir carries the biggest FishMT acreage?
Fort Peck Lake, printed by FWP at 249,240 acres.
Why do some lake sizes say mapped outline?
FishMT prints a size for 210 of these waters; the rest show the FWP layer polygon area, a mapping figure rather than a surface-acre number.
How are Lake Koocanusa and Bighorn Lake measured?
Their outline figures cover only the Montana part, since the FWP layer stops at the state line.
Do any of these lakes touch a reservation or a national park?
21 lake pages flag a reservation and 18 flag Glacier or Yellowstone, where tribal or Park Service rules come on top of a state license.
How many lake pages list an access site with a ramp?
36 lake pages list fishing access sites or state park ramps from the FWP layers.
Which Montana waters carry exception rules of their own?
60 lake pages quote exception headings from the 2026 regulations, dated to that edition.
Can I see how full a Montana reservoir is running?
A USACE reading, the Fort Peck weekly update or a USGS lake gauge appears on 13 lake pages; 86 show 2026 FishMT stocking rows and 50 carry the FWP consumption advisory flag.
