Fishing at Grass Lake, Garfield County, Utah

• Overview

  Out in Garfield County, Utah, sits Grass Lake. The setting is mixed forest. Surface area runs to about 8 acres — small enough to read in one session. Head to Monroe, 54 miles away, for anything you forgot. It is 151 miles to Provo, the nearest city. Rules here are straightforward: one county, one set of rules. It fits into a morning if you live close.

• Where to Fish on Grass Lake

  Depth here is unknown, so count the lead down before committing. Look for the band where the shallows give up and the bottom falls away. On a natural lake the weed line and the shelf beyond it do the work. Garfield County records list brown trout, rainbow trout, brook trout, Arctic grayling and black-spotted cutthroat trout among the fish reported. County data is a starting point rather than a guarantee. Grass Lake responds to conditions more than to tactics.

• Seasonal Patterns

  Between January at about 22°F and July at about 58°F, the water has a wide range to work through. Fishing here follows the temperature more than the calendar. The open season starts with the thaw, near enough early May. Expect the water usable from around early May until roughly late November. From the thaw to midsummer the fishing improves week by week. Grass Lake fishes to that pattern most years.

• Tackle & Baits

  We have no record of the rules that apply on this bank. Nothing is mapped in the way of a ramp or car park within a short radius. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Rules for this water may differ from the county norm. Some water is controlled locally without a sign saying so. Kings Pasture Reservoir at 1.4 miles is the sensible second choice. Rules at Grass Lake are worth checking on the day.
