Description:
Harmless. Scales keeled. Body is dark brown or slate gray, with cream-colored or yellow stripes along the sides of the body just above the belly. The belly is cream or yellow with two dark stripes. In older females, the belly may be dark. Young look like miniature adults. Relatively stout-bodied brown or dark olive water snake. Side stripe bordered below by a narrow, irregular black stripe along the outer edges of belly scales. Sometimes a midback light stripe is present. Belly plain yellow or off-white, the hind third with a faint dark line or row of dots down the center. Stripes and belly more yellow and midback light stripe more frequent in juveniles.
Adults normally grow 457- 710 mm (18-28 inches) in TL; largest specimen from Kansas: female (KU 188175) from Lyon County with TL of 1,029 mm (40 5/8 inches) collected by Robert F. Clarke on 11 June 1960; maximum length throughout range: 47 inches (Conant and Collins, 1998).

Distribution:
The still-water, prairie equivalent of the queen snake, it lives in and along banks of soft-bottomed, heavily vegetated lakes, ponds, sluggish streams, sloughs, and roadside ditches. Generally found along riparian areas in the eastern half of the state.
Few records exist for northeastern Kansas (one each from Brown and Doniphan counties) but they are substantiated by records from southeastern Nebraska and northwestern Missouri.

Natural History:
Occurs along the margins of mud-bottom marshes, oxbow lakes, rivers, and streams; particularly likes roadside ditches abundant with crayfish. Active from late April to October, this snake breeds in the spring and an average litter of 16 young are born July–September. Feeds almost exclusively on crayfish.
Mates in late April or May and gives birth to 10-20 young in late July, August, or September. Newborn 15-25 cm TL.

Occurrence Activity:
White dates indicate there is at least a single recorded occurrence on that date. The darker blue a date is, the greater the relative number of observations for that date.
Remarks:
The given locality of Harper County specimen (KU 186009) is actually in Barber County.
Additional surveys along the eastern sections of the Smoky Hill, Saline, Soloman, and Republican rivers may yield specimens.
