• Where to Fish on Mercer Lake

  Nothing we hold settles how deep this runs. Weed, then depth: that is the order to fish a water of this kind. On a natural lake the weed line and the shelf beyond it do the work. County-wide records name walleye, northern pike, yellow perch, muskellunge and rainbow trout. Records at this level tell you what is in the area. Mercer Lake gives up its fish to patience rather than distance.

• Seasonal Patterns

  Climate records put July near 66°F and January near 10°F. Winter shuts things down for a spell, then spring reopens them fast. Winter locks it down, and mid April brings it back. Break-up sits around mid April on average, with the water closing again about late November. Reckon on open water from spring through to late autumn, with May and June the strongest. Time your trip to Mercer Lake by conditions rather than dates.

• Tackle & Baits

  Access status is simply unknown for this water. It formed naturally, so levels move with rainfall rather than with a gate. You can launch from a ramp around half a mile away. Parking is close: a car park sits half a mile from the bank. This sits inside Mercer Station, so read the reserve notices first. Some banks are open only from a marked point. Where parking is tight, arriving early solves most problems. For a change of water, Lake Tahoe is 0.8 miles distant. What applies at Mercer Lake may have changed since it was mapped.
