Gravelly Range Lake in Lewis and Clark County: How and When to Fish It

• Overview

  Gravelly Range Lake lies in Lewis and Clark County, Montana. The setting is pine and birch on every side. At about 126 acres, a day is enough to walk the shoreline properly. It is a smooth basin, with the interest below the waterline rather than along it. The nearest town is Helena Valley Northwest, 16 miles away. The big place round here is Billings, 198 miles distant. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Gravelly Range Lake

  There is no published depth for this one, so start shallow and work out. The shallow end warms first and pulls fish in ahead of the rest. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Lewis and Clark County names rainbow trout, sockeye salmon and brown trout. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. Gravelly Range Lake repays a walk before the first cast.

• Seasonal Patterns

  On the long-term average, July reads 62°F and January reads 21°F. The season turns properly here, and fish follow it closely. Break-up comes around early April, and the run that follows is short and strong. The lid tends to go about early April and return around late November. Late spring and early autumn carry the year between them. The season on Gravelly Range Lake rarely departs from it.

• Tackle & Baits

  The rules here are undocumented as far as public sources go. It formed naturally, so levels move with rainfall rather than with a gate. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. For the trout, small spinners and a box of nymphs cover both approaches. A landowner's word beats anything printed elsewhere. Rules for boats are stricter than rules for the bank in many places. Flesher Lakes, 13 miles away, makes the obvious fallback. Treat access at Gravelly Range Lake as something to verify.
