looked up your snake I do believe it is an eastern garter snake. says it is the most distributed snake in north america. Habitat near water- wet meadow, marshes, prairie sweles, and irrigation and drainage ditches. has 7 upper lip scales not that you want to search that ( i'm guessing) lol
most acitve during the day looks for frogs and toads, salamanders, and worms, may eat small mice and fish. Ill tempered when caught and will bite, and give off a musk smell. but will tame quickly and become docile. recorded longevity 10 yrs. also know as common garter snake
information from national audubon field guide reptiles. platelet 539 info on page 674. hope it helps. they are plentiful so if you kill it there are more, they reproduce in groups of 10.
