It is a small, almost unremarkable creek when it starts out near K-42 highway in the northwestern corner of Sumner County.  To many people, it is first seen as it crosses under Highway 49, just north of Conway Springs.  
As it begins to flow away from Conway Springs, it starts to gain in size and scenic beauty.  A popular fishing spot for many locals is off of Springdale Road, just northeast of Conway Springs.  
Many Wellington residents know it as one of the venues for competition during the Great Race that is held every year in Woods Park.  The creek is of moderate size by the time it reaches Wellington , with many people coming to this area to fish, especially around the spillway.  
According to the National Weather Service, Slate Creek, near Wellington, has crested at rather high levels in the past few decades.  
On July 31st of this year, it reached a height of 20.07 feet.  During the Flood of 2016, Slate Creek reached 23 feet on Sept. 10th of that that year.  On April 27th of 2009, Slate Creek peaked at 23.80 feet.  The year before that, the creek reached 24.28 feet on Sept. 13th, 2008.  The highest recorded amount, however, was 25.82 feet on June 17th, 1975.
Water begins to overflow the banks when it reached nineteen feet.  Minor low land flooding can be expected along the creek.  
When the creek reached 23.5 feet, the Kansas Turnpike will begin to flood between mile marker 14 and 15 which is near the vicinity of Slate Creek. Expect possible road closure near this section of the turnpike if creek continues to rise.
Finally, when the creek reaches 25.7 feet, water begins to flow across Highway 81 just to the north of the river gage site located south of town.
Slate Creek lends itself to two locales near its route after it leaves Wellington.  Slate Creek Wildlife Area is southwest of Oxford.  It covers 947 acres, of which fifty are wetlands.  There is no automobile traffic allowed in the wetlands, but hiking in this area makes for a very positive experience for the wildlife.  
White-tailed deer, coyotes, raccoons, and muskrats are often spotted in this area.  Many varieties of birds can also be seen, as many avid bird watchers and photographers can be seen in this area.  
A small observation tower is installed in the area.
Slate Creek Bed and Breakfast is also located not far from there.  It has been the location of many a wedding or get-together over the years.  
Southeast of Oxford, Slate Creek empties into the Arkansas River.
