Climate averages put the opening at about late April and the closing near early December. Right after break-up, and again as the nights sharpen, is when to go. Anyone fishing Big Limestone Lake regularly works to that calendar.

• Tackle & Baits

  Public data does not answer the access question here. It formed naturally, so levels move with rainfall rather than with a gate. Nothing is mapped in the way of a ramp or car park within a short radius. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Some banks are open only from a marked point. Signs go up and come down, so check on the day. The nearest alternative is Little Limestone Lake, 1 km out. Treat Big Limestone Lake as unsettled until someone local tells you otherwise.
