• Seasonal Patterns

  In an average year July sits at 16°C and January at -18°C. Everything is compressed into the middle of the year. Count on hard cover from midwinter, and open water from early May. Open water usually runs from early May until about mid November. Reckon on open water from spring through to late autumn, with May and June the strongest. Expect Hainsworth Lake to follow that timing.

• Tackle & Baits

  Nothing in our records says who may fish here. This is a natural basin, not a dammed one. Public mapping records no formal access here, so plan for a walk and soft ground. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. A phone call first saves an afternoon. Barbless rules turn up on managed water more often than not. Should this one be busy, Arrell Lake is 4.9 km off. Treat access at Hainsworth Lake as something to verify.
