Putah Creek in California

Putah Creek has a fascinating history.

In the early 1900s, Putah Creek was a thriving stream that was teeming with steelhead. But by the late 1980s, extended drought caused the Creek to go dry.

A subsequent controversial lawsuit was resolved with the signing of the Putah Creek Accord in 2000. This resulted in the construction of Monticello Dam, and the releases from the dam have helped restore Putah Creek to its former glory, albeit it is now tailwater trout fishery.Now, the fishery is once again a great destination for fly fishermen looking for that perfect catch. You can find plenty of wild rainbow and the occasional brown trout in these waters.

We are grateful for all the effort put into restoring this Creek and, if you visit, we guarantee you will be too. 

About Putah Creek

Fly Fishing in Putah Creek in California

Putah Creek is a 85 mile long stream located in Northern California. It is a tributary of the Yolo Bypass and, eventually, the Sacramento River. The name “Putah” comes from the Lake Miwok language. The original name for the Creek was “puta wuwwe” meaning “grassy creek.” The United States Board on Geographic Names rejected the name “Puta Creek” due to its resemblance to an offensive term in Spanish.

Putah Creek rises on the east side of Cobb Mountain, and flows to Lake Berryessa and the Monticello Dam. Near the southeast corner of the lake, the Creek leaves Napa County and forms the boundary between Yolo and Solano Counties, for about 8.1 miles before emptying into the Putah Diversion Dam. Below Lake Solano, the Creek travels for 23 miles and then meets the Yolo Bypass. Putah Creek is fed by its tributaries Dry Creek and McCune Creek.

At Putah Creek, you will see rainbow and brown trout. The Creek is known by its nickname the “Green River” due to its rich aquatic vegetation, and was even the subject of a Creedence Clearwater Revival song, “Green River.” The band’s lead singer, John Fogerty, often visited the Creek on vacation as a child.

The Creek is also in close proximity to the Bay Area and Sacramento, so you can enjoy exploring plenty of other attractions in the area as well. As Creedence Clearwater Revival puts it, “If you get lost come on home to Green River.”

Best Places to Fish Putah Creek

The best trout fishing occurs below Monticello Dam. Because the discharges keep the water cool throughout the year, you can visit during any season and still have success catching trout. Trout as large as twenty inches have been caught in this section.

The California Department of Fish and Wildlife regulations dictate that you must use artificial lures with barbless hooks. Additionally, the Creek is catch and release only from November 16 to the last Saturday of April. Keep in mind that these regulations are subject to change, and be sure to get the latest information before making your visit. 

Access to the stream is excellent, as the Creek parallels Highway 128. There are five county fishing accesses, which are ideal entry points for anglers. You must pay to park in these areas, but you can also park alongside the road. 

While you can wade in some areas, the high volume discharges make this dangerous in sections, particularly in the summer. It’s best to fish from the banks.

Stream Flow and Current Conditions

Be sure to check the stream conditions before heading out to fish Putah Creek. The USGS stream gauge near Winters, California provides a good indication of current conditions.

The graph below shows the stream flow (discharge) for the past 7-days. If flows are considerably above or below historical norms (yellow triangles on the chart) then fishing conditions ma not be ideal.

Best Time to Fish Putah Creek

Putah Creek offers year round fly fishing opportunities. The most common hatches you will see on this stream are Blue Winged Olives and ever present midges. The Creek also has its share of Caddisflies, most notably Spotted Sedges. You can also have luck using terrestrial imitations in the summer. Streamers are also effective to mimic sculpin and other baitfish present in the Creek.

Fishing is productive all year, although you will want to avoid the Creek on the coldest days of winter. The best time to visit is probably early spring or late fall.
