Swanberger Reservoir in Lassen County: How and When to Fish It

• Overview

  Lassen County, California, is where Swanberger Reservoir sits. It sits at 5,682 feet above sea level. Around 68 acres of surface means several distinct areas to work. The full circuit measures close to 2.1 miles on foot. Susanville is the closest town at 32 miles. The big place round here is Chico, 95 miles distant. One jurisdiction covers this water end to end.

• Where to Fish on Swanberger Reservoir

  There is no published depth for this one, so start shallow and work out. Inflow corners move water, and moving water gathers fish. Draw-down through summer strips the margins, so follow the water out. Across Lassen County, recorded fish include rainbow trout, tahoe sucker and Sacramento sucker. Those are county-wide records, so not every one of them will be in this water. On Swanberger Reservoir that means starting tight and working out.

• Seasonal Patterns

  Long-term averages put July at about 63°F and January near 27°F. A lid forms in a hard winter only. In milder years the edges alone go, and the middle never sets. The cooler months are the comfortable ones to fish here. At Swanberger Reservoir the season follows that pattern closely.

• Tackle & Baits

  The access position is unclear from public sources. This one is mapped as intermittent, so a wasted trip is a real risk in a dry year. Formal access is not mapped, so the last stretch is likely on foot. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Check whether a boat is allowed before you tow one. Where tickets apply, they are sold in the nearest town rather than on the bank. For a change of water, Heath Dam Reservoir is 1.7 miles distant.
