Gretchtown was briefly designated as the county seat of Nobles County, an imaginary county seat for a county that, at that time, had no residents. When a route for the St. Paul and Sioux City Railway was surveyed in 1871, it was located far south of the Graham Lakes region. No towns or villages existed in Graham Lakes Township until 1879 when Kinbrae and Dundee were established. Neither town grew beyond a few hundred residents. Thus, the Graham Lakes region has remained entirely rural, and the lake shores of both East Graham Lake and West Graham Lake remain undeveloped. These lakes were first noted on Joseph Nicollet's 1842 map based upon his explorations of the late 1830s and early 1840s. Nicollet named the lakes after Joseph Duncan Graham. Graham served as a commissioner for the survey of the northeast segment of the boundary between the United States and Canada from 1840 until 1843. Fishing Graham Lakes are known as exceptionally good fishing lakes. East Graham is managed primarily for walleye and northern pike and secondarily for black crappie and yellow perch. A population assessment was conducted during the week of June 4, 2007 using 3 gill nets and 8 trap nets. Black Crappies ranged from to , and their numbers were the highest since sampling of the lake has been conducted. Northern Pike ranged from to . Walleye were also abundant, and 59% of those sampled were or greater. Most fish from East Graham Lake are safe to eat. However, pregnant women, women who may become pregnant and children under age 15 are advised to refrain from eating walleye more than once per week due to mercury levels. West Graham is primarily managed for walleye with black crappie and channel catfish as secondary species. Walleye fry and fingerlings are stocked in successive years, with the third year left blank. A population assessment conducted on June 4, 2007 found that walleye range from 6.9 to in length. Black crappies range from to . The average black crappie swimming in West Graham Lake is thought to be nearly 1/2 pound. Channel catfish average . There are no advisories for consumption of fish from West Graham Lake. Public Access Fury Island and Maka-Oicu County Parks are located on East and West Graham Lakes. Maka-Oicu County Park is located on the northeast shore of West Graham Lake and provides for camping, lake access, natural
