A broken sky giving spells of shade, with flat calm through the day and pressure easing off. Expect most activity at Shirley Lake around bays that hold the day's warmth. A broad window opens from night into morning. Commit to the pattern once the first fish shows. The autumn feed-up is on; baitfish areas are the key.

Fremont County in Wyoming is where Shirley Lake sits. This is lake country bush ground. This is a pocket water of some 4 acres, and every part of it is reachable from the bank. Most waters listed here for Fremont County are larger. Pinedale at 28 miles is the nearest place to stop. For a city, Billings is 186 miles off. It lies deep inside the county rather than near an edge.
No depth figure has reached our records, which makes a plummet useful. A natural lake fishes on cover, and cover here means weed and timber. Read the surface for the wind lane, then fish the edge of it. Open biodiversity records for Fremont County list brown trout, rainbow trout and white sucker. Those are county-wide records, so not every one of them will be in this water. On Shirley Lake the first feature you find is usually worth a session.
The warmest month averages 50°F, the coldest about 15°F. The freeze arrives properly here and holds. Ice-out usually falls in late May, and the weeks after it fish hardest. On the long-run averages the water opens up around late May and starts locking again about early November. Late spring and early autumn carry the year between them. At Shirley Lake the season follows that pattern closely.
Whether the bank is open is not something our records settle. No made access appears within a short radius, so plan to park on a verge and walk. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Take the rules with you rather than trusting memory. Where tickets apply, they are sold in the nearest town rather than on the bank. Failing this one, try Valaite Lake, 0.3 miles away. Check the position on Shirley Lake before loading the car.
