DuPuy (pronounced Duh-pew) Spring Creek is a three-mile stretch of trout stream sandwiched between the scenic Absaroka and Gallatin ranges in the Paradise Valley south of Livingston. A small tributary of the Yellowstone River, the creek supports a sought-after population of wild brown, cutthroat, and rainbow trout.
DuPuy Spring Creek is a downstream continuation of the same creek known upstream as Armstrong Spring Creek, with access controlled by different landowners.
According to Yellowstone Angler, which can outfit fishermen on DuPuy, the creek offers water ranging from wide, shallow flats to deep, narrow runs, with chutes, drop-offs, and riffles providing varied habitat. Heavy insect hatches make spring, summer and fall productive, and weed growth protects populations of scuds, sow bugs, mayfly nymphs and midge larvae, allowing for good nymph fishing all year.
Access is limited to 16 anglers per day. June 15 to September 14, fees are $100 per rod per day. April 15 through June 14 and September 15 through October 14: $75. October 15 to April 14: $40.
