Royal Arch Lake in Mariposa County: How and When to Fish It

• Overview

  California holds Royal Arch Lake, in Mariposa County. Everything around it is open valley. At 8 acres it is the sort of place you fish for an evening rather than a day. The nearest place of any size is Yosemite Valley, 12 miles away. The big place round here is Clovis, 53 miles distant. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Royal Arch Lake

  There is no published depth for this one, so start shallow and work out. This is a lake, so the margins and the first drop matter most. The shallow end warms first and pulls fish in ahead of the rest. Across Mariposa County, recorded fish include rainbow trout, brook trout and brown trout. Those are county-wide records, so not every one of them will be in this water. Royal Arch Lake repays a walk before the first cast.

• Seasonal Patterns

  Long-run averages give August about 61°F and February about 32°F. The freeze here is occasional rather than annual. Cover comes and goes, so treat it with suspicion rather than trust. The cooler months are the comfortable ones to fish here. Plan around that when you fish Royal Arch Lake.

• Tackle & Baits

  Ownership and access are not documented in what we hold. The map shows no ramp or car park nearby, so this is a walk-in water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Sort the permit out before you load the car. Close seasons apply to some species and not others. Minnow Lake at 0.7 miles is the sensible second choice. Nothing on Royal Arch Lake should be assumed from this page alone.
