Cloud from horizon to horizon today, with air barely moving with pressure climbing. Fish at Summerville Lake should hold close to the first drop-off and weed lines. Expect the better fishing from afternoon into evening. Give the likely spots time before moving. Cooler water spreads fish back across the shallows.

Set in Lincoln County, Montana, this is Summerville Lake. Beyond the shoreline you have lake country bush. Surface area runs to about 17 acres — small enough to read in one session. Nearest place of any size is Eureka, 6.1 miles away. The big place round here is Lethbridge, 117 miles distant. It lies deep inside the county rather than near an edge.
There is no published depth for this one, so start shallow and work out. Still water like this holds fish on the edges rather than out in the open. Where the bottom changes texture, fish gather; find that line. Fish documented in Lincoln County include rainbow trout, sockeye salmon, brook trout, northern pike and largemouth bass. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. The shape of Summerville Lake rewards a slow walk along one bank.
August is the warm end of the year here, averaging about 62°F, while January sits near 20°F. The year splits cleanly: hard water, then open water. The lid usually sets by midwinter and gives way around early April. On average, early April opens the water and late November closes it again. Spring is short and heavy here; autumn is longer and steadier. Summerville Lake fishes to that pattern most years.
Our records carry no access rule either way. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. A small crankbait along the drop and a worm in the thick stuff cover the bass. Sort the permit out before you load the car. Some water is controlled locally without a sign saying so. Failing this one, try Frank Lake, 0.3 miles away. What applies at Summerville Lake may have changed since it was mapped.
