Fishing at Appendix Lake, Idaho County, Idaho

• Overview

  The Idaho County end of Idaho holds Appendix Lake. This is rolling bush ground. At 2 acres it is the sort of place you fish for an evening rather than a day. Most waters listed here for Idaho County are larger. You are 33 miles from Joseph. The big place round here is Boise, 120 miles distant. A border sits close enough to be relevant to the paperwork.

• Where to Fish on Appendix Lake

  Depth is unmeasured here, so let the shoreline guide you. The shallow end warms first and pulls fish in ahead of the rest. Weed, then depth: that is the order to fish a water of this kind. Across Idaho County, recorded fish include rainbow trout, Chinook salmon, cutthroat trout, bull trout and brook trout. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. The shape of Appendix Lake decides where the fish sit.

• Seasonal Patterns

  The warm month here averages 52°F; the cold one sits at 20°F. Cold winters and warm summers give a wide working range. Winter locks it down, and mid May brings it back. Break-up sits around mid May on average, with the water closing again about mid November. Reckon on open water from spring through to late autumn, with May and June the strongest. Time your trip to Appendix Lake by conditions rather than dates.

• Tackle & Baits

  Our records carry no access rule either way. Mapping records no facilities at all near this water. For the trout, small spinners and a box of nymphs cover both approaches. Parking is often the real limit rather than the bank itself. Where tickets apply, they are sold in the nearest town rather than on the bank. Should this one be busy, Rock Island Lake is 0.1 miles off. Nothing here settles the position at Appendix Lake for certain.
