|Dunlap is centered on an old railroad grade that runs diagonally NW-SE and is marked by diagonal modern roads in places. Note two cemeteries east of the town. The northern one is the African-American (exoduster) cemetery. ESU Dunlap Bottoms is located in the SE¼ of section 13 (*). Portion of the Americus, Kansas 7.5-minute topographic map (1972).

The lake was developed early for summer cabins and recreation. Sixty cabin sites were established by 1944, and the lake became well known in the 1950s for sailing, water-skiing, swimming, and fishing. During the 1960s and 1970s, the recreational significance of the lake began to dwindle, however, with construction of large reservoirs in eastern Kansas by the U.S. Army Corps of Engineers. Lake Kahola now has approximately 200 cabin sites plus a year-round caretaker in residence.

Through the twentieth century, building lots were leased from the city under a long-term arrangement with the Kahola Park Cabin Owners Association. Early in this century, however, the city began the complex legal process of selling the land to the cabin owners association. This sale was completed in 2007, when the renamed Kahola Homeowners Association (KHA) took private ownership of the lake and surrounding property.

Recognizing these issues, the cabin owners association began an effort in 2000 to place permanent survey markers at the corners of all building lots in the park. To supplement the ground-based survey markers and lot measurements, large-scale airphotos were selected as the tool for documenting lake-shore development and lot boundaries. Vertical kite aerial photography was conducted during the winter, leaf-off period in order to obtain views with minimal obstruction from trees (Aber and Aber 2003). Conducting vertical photography around an irregular shoreline proved challenging, especially in regard to numerous power lines, roads, fences and trees in vicinity of the buildings. Lot boundary markers were identified with additional ground survey.
