Jensen, Utah sits at the edge of Dinosaur National Monument, and the fishing here is almost entirely tied to the Green River — a cold, clear tailwater that runs through canyon country and draws anglers who know what they're looking for. The three main access points in the area each have a different feel. Split Mountain Group Campground puts you right on the river after it exits the canyon, where the water widens and slows. Green River Campground is a straightforward base for wade fishing or floating a stretch of the main channel. Jones Hole National Fish Hatchery is the outlier — it sits up a side canyon and feeds Jones Hole Creek, a small tributary that runs into the Green and holds fish in its own right. The Green River in this stretch is not a trophy tailwater in the Gold Medal sense, but it holds brown and rainbow trout along with the native Colorado River fish species that the hatchery program supports. Flows here are managed upstream, so checking current CFS before you go matters more than it does on freestone streams. Access is generally good, crowds are manageable compared to the more famous sections downstream, and the canyon setting makes even a slow day worthwhile.
The Green River in this area holds brown trout and rainbow trout, along with native warmwater species in slower sections. Jones Hole Creek, fed by the hatchery, also holds trout and is worth fishing on its own before it joins the main river.
Yes, a valid Utah fishing license is required. This stretch of the Green River falls within Dinosaur National Monument, which can carry additional rules on top of state regulations — check both Utah Division of Wildlife Resources and the National Park Service before your trip, as regulations can differ from what you're used to on other Utah waters.

Spring and fall are generally the most productive seasons on the Green River here. Summer can bring higher water temperatures in slower sections, which pushes trout into deeper, cooler pools. Runoff in late spring can blow out visibility, so checking river flows before you commit to a date is worth the two minutes it takes.
Early morning and late afternoon are consistently the most active windows, especially in summer when midday heat slows things down. Evening hatches on the Green can be productive if you're set up and ready before the light goes.
All three access points are reachable without technical hiking or a boat, which makes them accessible to beginners. That said, the Green River rewards anglers who can read moving water and present a fly or lure naturally — if you're new to river fishing, spending some time learning to mend line or work current seams will make a real difference here.
