The flag of Douglas County was approved by the Board of County Commissioners and designed by Murray Kahn, a former operator of a flying school at the county's airport. Inside of the diamond, Lake Tahoe is shown as well as the natural scenery, and a rider on horseback. This flag was designed in preparation for the Nevada State Centennial. source: a news clipping on Facebook Daniel Rentería, 24 August 2023
This flag seems to be a ~3:5 horizontal bicolor of orange over black with a
landscape scene inside a horizontally oblong rhombus centered on it and,
centered along the bottom, the word "Douglas" in white slab serif capitals. (I
used Choplin typeface.)
The depicted scene features a rider with orange
shirt and black pants on horseback riding flywards on the foreground of the
hoistside half of the rhombus, the horse and all other details in white with
thick black edge lines; background shows white mountains agaisnt pale blue sky
rising from a light green ground; on it, visible mostly on the flyside half of
the rhombus, a pale blue lake with three dark green trees in its near shore and
another on the far side.
