For an angler judging whether the fishing is worth the drive, the stocking record is the fishing report. Norbury Lakes is a put-grow rainbow fishery, not a self-sustaining wild population: 124 recorded releases between 1938 and 2026, all Rainbow Trout. The most recent release, in 2026, was 1,000 yearling Rainbow Trout of the Blackwater R strain, the same broodstock line used across many of the region's put-grow lakes.
That consistency, roughly 1,000 Blackwater R yearlings a season in recent years, is what keeps the lake fishing well from one year to the next: last year's stocked cohort grows on through the season while the next spring's release tops up behind it.
