Angling methodologies are straightforward: bait fishing with PowerBait or worms from accessible banks, or lure fishing with small spinners and spoons. Fly fishing is highly effective, utilizing nymphs and dry flies, demanding a delicate presentation due to water clarity.

Access to this secluded lake is by foot, requiring carry-in watercraft (kayaks, float tubes); no motorized boats are permitted. All anglers must possess a valid California fishing license. Strict adherence to current California Department of Fish and Wildlife (CDFW) regulations, including specific bag limits and any applicable National Park Service rules, is compulsory for legal compliance and the preservation of this unique natural resource.
