[3] Kelsey Creek, from Forest Lake downstream to around Glenbrook, is a federally designated flood boundary.

[4] Originally the Forest Lake property was the home of James Hartford Smith, who bought the land in 1868.

[16] His property was divided between seven nieces and nephews, one of whom was Vince Emerson's son Don, who lived near the resort in Cobb.

Don in turn owned and ran it with his wife Dorothy from 1950 to 1963, creating the Hoberg's Forest Lake Golf Course in 1954.

Supervised activities were provided for children, including swimming in the pool, games, hay rides and special meal times.

[6] As of 1989 7.8 acres (3.2 ha) of vacant land beside the Forest Lake area was zoned for of low-density residential planned development.

[23] A plan for the Cobb Mountain Area issued in 1989 discussed developing Forest Lake as a park facility.

[24] The 1989 Cobb Mountain Area plan recommended that its recreational development be limited to low-cost passive facilities such as picnic sites, trails and walkways, and should be improved for outdoors activities such as fishing and wildlife observation.

[3] The Cobb Area Council held a public meeting on 18 April 2019 where it was reported that the county was still not looking at changing Forest Lake into a park, although there was local support for the idea.
