• Where to Fish on Alkali Reservoir

  Our records hold no depth for this water. The arms fish better than the open middle whenever the water is up. Look for where the old bank line still shows under the surface. Delta County records list rainbow trout, white sucker, flannelmouth sucker, bluehead sucker and brown trout among the fish reported. Records at county level tell you what is around, not what is stocked here. Alkali Reservoir gives up its fish to patience rather than distance.

• Seasonal Patterns

  Average temperature peaks around 77°F in July and bottoms out near 29°F in January. Fishing continues through most of the calendar, with quiet spells rather than closures. Cover comes and goes, so treat it with suspicion rather than trust. June to September is hot work, so the first and last hours are what count. It sets the rhythm of the year at Alkali Reservoir.

• Tackle & Baits

  Access is not recorded for this water. Mapping is blank for access, so scout the approach before committing the car. For the trout, small spinners and a box of nymphs cover both approaches. Some banks are open only from a marked point. Where the way in crosses private ground, ask first. Winkler Reservoir at 4.8 miles is the sensible second choice. Rules at Alkali Reservoir are worth checking on the day.
