Soft grey light all day today, with a light SSW breeze and pressure easing off. Activity on Lake Diaphanous should centre on reed fringes and open pockets. Save your energy for the night. Work the productive water thoroughly. Falling temperatures are switching fish back on.

Night
You will find Lake Diaphanous in Park County, Montana. Country round the bank runs to mixed forest. Small at around 9 acres: two anglers spread out cover most of it. It sits higher than most water we list in Montana. Head to Livingston, 35 miles away, for anything you forgot. The big place round here is Billings, 84 miles distant. No border sits close enough to matter.
Depth figures are not published for this one. The productive water is a rod length or two out, not a hundred. Bays and points beat straight shoreline every time on water like this. Records held for Park County cover rainbow trout, brook trout and california golden trout. Records at this level tell you what is in the area. The shape of Lake Diaphanous rewards a slow walk along one bank.
Temperature averages peak at 49°F in July and bottom out at 15°F in January. A solid cap is the normal state through winter. Break-up comes around early June, and the run that follows is short and strong. Average temperatures cross freezing around early June in spring and again near early November in autumn. Late spring and early autumn carry the year between them. That shapes the year on Lake Diaphanous.
There is no clear statement anywhere on who can fish it. We find no slipway, car park or made path within a short radius, so treat access as rough. 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 Pinchot at 0.7 miles is the sensible second choice. For Lake Diaphanous, the notice at the access point is the final word.
