Lake Agnes is a large lake at the head of the Boulder River, in the Lac La Croix drainage basin, 20 miles ESE of Crane Lake and 23¾ miles NNW of Ely. Over 2¼ miles long and up to a mile wide, the lake's 984 acres are relatively shallow for a lake of this size, with a maximum depth of only 30' and almost half the lake less than 15' deep. Agnes is fed by the Nina Moose River and its tributaries (the Oyster, Moose, and Portage rivers and a host of smaller streams) and is, in turn the source of the Boulder River. The Boulder bends and twists over 3½ miles, and through a couple of rapids, on its journey to Boulder Bay, but 1¼ miles from Agnes as the loon flies.

At the far north end of the Agnes, a 24 rod portage connects with the Boulder River while a longer, 155 rod carry at the north end of the eastern bay also connects with the Boulder, though 1½ miles farther downstream. In the southwestern end of Agnes is the mouth of the Nina Moose River, while farther up the western shore, a 160 rod portage connects with its tributary, the Oyster River, 1¼ miles above its confluence with the Nina Moose.

Most of the forest surrounding Lake Agnes dates back to the fires of 1864, though a significant area of mixed age classes, including remnant stands surviving from the fire years of 1755-1759 and 1681, is present along the eastern shore and northeast to Boulder Bay. The area escaped the big blowdowns of the 4th of July 1999.


Lake Agnes supports some 25 established campsites, well distributed along its 10 miles of shoreline.

Planning Considerations

Lake Agnes is a link in the east/west Pauness/Boulder Bay route, which heads north and east out of Upper and Lower Pauness on the Little Indian Sioux River through Shell, Little Shell, Lynx, Ruby, Hustler, Oyster, and Lake Agnes, to Boulder Bay on Lac La Croix. Agnes also provides access up the Nina Moose River to Ramshead, Lamb, and Nina Moose Lake as well as the Moose and Portage rivers beyond. All connections in and out of Agnes are, interestingly enough, riparian.

Agnes is included in Beymer, The Boundary Waters Canoe Area, vol. 1, The Western Region, routes 7, 11, 13, 15, 16, 17, 18, 19, and 20.


Lake Agnes supports populations of Northern Pike (Esox lucius), Rock Bass (Ambloplites rupestris), Sauger (Stizostedion canadense), Shorthead Redhorse (Moxostoma macrolepidotum), Smallmouth Bass (Micropterus dolomieui), Tullibee (Cisco) (Coregonus artedi), Walleye (Stizostedion vitreum), White Sucker (Catostomus commersoni), and Yellow Perch (Perca flavescens).
