  We hold no survey for this water; read the slope of the shoreline instead. The productive water is a rod length or two out, not a hundred. Still water like this holds fish on the edges rather than out in the open. Public occurrence data for Lake and Peninsula Borough names sockeye salmon, Chinook salmon and Arctic grayling. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. On Lake Grosvenor the obvious spot is not always the productive one.

From the thaw to midsummer the fishing improves week by week. Time your trip to Lake Grosvenor by conditions rather than dates.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. No dam controls it, and the level follows the season. No built facilities appear in mapping around this water. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Ask in the nearest town if you are unsure. Keep proof of licence with you rather than in the car. Lake Coville sits 9.5 miles off and takes the overflow. Ask locally about Lake Grosvenor if anything is unclear.
