• Where to Fish on Lake Alva

  There is no published depth for this one, so start shallow and work out. The productive water is a rod length or two out, not a hundred. A soft bed grows weed late into autumn, which keeps fish shallow. Survey and observation records for Missoula County include rainbow trout, brook trout, cutthroat trout, northern pike and sockeye salmon. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Fish Lake Alva where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  The warm month here averages 60°F; the cold one sits at 20°F. Winter shuts things down for a spell, then spring reopens them fast. Expect a solid lid for months and a thaw around mid April. Ice usually gives way near mid April, and forms again about late November. The shoulder weeks of the open season are the productive ones. That shapes the year on Lake Alva.
