I start seeing snakes crawl in late september, normal here. It could be seasonal but if a creek dried up in late august there'd be no food left there by now. Might have forced them to move. Snakes only crawl for food, breeding and colder weather. They'll stay at a regular food source, once gone, they move.
I had just looked for this story fairly recently, because it is the time of year that snakes will go back to a snake den for the winter.

Katherine McHale Slaughterback (July 25, 1893 – October 6, 1969), popularly called
Rattlesnake Kate, but also known as
Kate Garner, was a woman from
Colorado. She garnered fame for an incident in which she killed 140
rattlesnakes.
Early life
Katherine McHale Slaughterback was born on July 25, 1893 (or 1894
[1]) in a log cabin near
Longmont, Colorado.
Slaughterback attended nursing school at St. Joseph's School of Nursing
[1] and moved to
Hudson, Colorado.
[2] She was a skilled
taxidermist and frequently wore pants instead of dresses, which was unusual for women of her era.
[3]
Slaughterback married and divorced six times—one of her husbands was Jack Slaughterback.
[1] She had one son, Ernie Adamson.
[4]
Rattlesnake namesake
On October 28, 1925, Slaughterback singlehandedly killed 140
rattlesnakes.
[2] Slaughterback and her son Ernie were on horseback headed to a lake near her farm. Hunters had been there the day before, and she was hoping to find harvested ducks left behind. However, she instead found over 100 migrating rattlesnakes. She shot the snakes until she ran out of ammunition for her
.22 caliber Remington rifle, at which point she grabbed a nearby sign (allegedly, it said "No Hunting") and bludgeoned the remaining snakes to death.
[3]
Of her ordeal, Slaughterback later said:
I fought them with a club not more than 3 feet long, whirling constantly for over two hours before I could kill my way out of them and get back to my faithful horse and Ernie, who were staring at me during my terrible battle not more than 60 feet away
[2]
She was "frantic that [the snakes] would frighten the horse, and cause him to rear up and throw Ernie into the snakes."
[5] After she returned to her farm, a neighbor learned of what had happened, which eventually led to a reporter coming to photograph and interview her. She strung the dead snakes together on a rope for the photograph, which became infamous. She would later make herself a dress, shoes, and belt from the
snakeskins.
[2] The dress, made from the skins of 53 rattlesnakes, was particularly famous. She claimed later that she received an offer from the
Smithsonian Institution to buy it for US$2,000.
[5]
Her story became popular and was written about it the
New York Evening Journal. News of her exploits was reported as far away as Germany, Belgium, Scotland, France, England, Mexico, and Canada.
[6]
Later in life, Slaughterback raised rattlesnakes, milking them for their
venom and selling it to scientists in California.
[2] Three weeks before her death, Slaughterback donated her famous rattlesnake skin dress to the Greeley Municipal Museum; Ernie donated more of her possessions after her death, including her Remington rifle.

Happy hunting, Prl. 
that snake had better find a different home.
