Roy Lake in Marshall County: How and When to Fish It

• Overview

  Roy Lake sits within Marshall County in South Dakota. The water sits 1,785 feet up. The water covers around 3.0 sq miles, which puts most of it out of reach from the bank.

For a city, Fargo is 87 miles off. It lies deep inside the county rather than near an edge.

• Where to Fish on Roy Lake

  No figure exists for depth, so let the water show you. Look for the band where the shallows give up and the bottom falls away. The productive water is a rod length or two out, not a hundred. Across Marshall County, recorded fish include bluegill, common carp and northern pike. County records show what lives in the area; the local agency holds the water-by-water list. Roy Lake gives up its fish to patience rather than distance.

• Seasonal Patterns

  In an average year July sits at 71°F and January at 9°F. Cold winters and warm summers give a wide working range. The open season starts with the thaw, near enough mid April.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. This is a natural basin, not a dammed one. Public data records a boat ramp 0.9 miles out. Expect a half a mile walk in from where the car goes. There are toilets mapped about 0.9 miles away. Some banks are open only from a marked point. Close seasons apply to some species and not others. If the gate is shut, Cottonwood Lake at 2.5 miles is the nearest alternative. Treat Roy Lake as unsettled until someone local tells you otherwise.
