Clear overhead with good moonlight, with a decent NNE wind working the banks with pressure climbing. Activity on Thompson Reservoir should centre on flooded cover along the old banks. If you must go, go in the night. One good spot fished well beats five fished quickly. Shortening days concentrate the feeding into fewer hours.

Thompson Reservoir is one of the Lassen County waters in California. Height above sea level is 4,423 feet. It is pond-in-a-field scale, with the far bank a short lob away. It is a small entry by Lassen County standards. Nearest town is Burney, 28 miles off. It is 98 miles to Chico, the nearest city. It sits well inside its county, with no border complications.
Open data we checked carries no depth for this water. A natural lake fishes on cover, and cover here means weed and timber. The shallow end warms first and pulls fish in ahead of the rest. Records held for Lassen County cover rainbow trout, tahoe sucker, Sacramento sucker, brown trout and brook trout. What holds for the county may not hold for this water. On Thompson Reservoir the quiet end is the one worth the extra effort.
Long-term averages put August at about 66°F and January near 31°F. The year gives four workable seasons without severe ends. Hard water here is never dependable, so check for yourself before stepping out. Spring and autumn carry the year; summer squeezes it into the ends of the day. That shapes the year on Thompson Reservoir.
Access is not recorded for this water. It is recorded as intermittent, which means the basin empties in dry spells. Nothing built is recorded close to the bank here. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Check whether a boat is allowed before you tow one. Some stretches are reserved and marked as such on the ground. Nine Springs Reservoir sits 5.8 miles off and takes the overflow. The position on Thompson Reservoir is worth confirming on the day.
