Putah Creek(Patwin:Liwaito[3]) is a major stream inNorthern California,a tributary of theYolo Bypass,and ultimately, theSacramento River.The 85-mile-long (137 km)[2]creek has its headwaters in theMayacamas Mountains,a part of theCoast Range,and flows east through two dams. First,Monticello DamformsLake Berryessa,below which Putah Creek forms the border ofYoloandSolanoCounties, and then flows to the Putah Diversion Dam andLake Solano.After several drought years in the late 1980s, the majority of Putah Creek went dry, prompting a landmark lawsuit that resulted in the signing of the Putah Creek Accord in 2000. The Accord established releases from the dams to maintain stream flows in Putah Creek, with naturalflow regimeswhich spike in winter/spring and ebb in summer/fall. The restoration of natural flow regimes has resulted in a doubling ofriparianbird species and a return of spawning nativesteelhead troutandChinook salmon,as well as protecting the livelihood of farmers on the lower watershed.[4][5]
History and name
[edit]The true meaning of "Putah" in Putah Creek has been the subject of discussion and speculation. It was originally called "Arroyo de los Putos" (1844) and "Puta Creek" (1845), but the "Puta" form was rejected by theUnited States Board on Geographic Names,likely because of the resemblance to theSpanishwordputa(lit. "whore" ).[6]According to Erwin Gudde (1889–1969), the resemblance is "purely accidental". The revised fourth edition of Gudde'sCalifornia Place Nameshas the following entry:
Putah Creek[Lake, Napa, Solano Cos.]. FromLake Miwokpuṭa wuwwe"grassy creek" (Callaghan; cf. Beeler 1974:141). The similarity to Spanishputa"prostitute" is purely accidental. In the records ofMission San Francisco Solano (Sonoma Mission)of 1824, the natives of the place are mentioned with various spellings from Putto to Puttato. In the baptismal records ofMission Doloresanadulto de Putüis mentioned in 1817, and the wife of Pedro Putay in 1821 (Arch. Mis. 1:94.81). In 1842 the stream was well known by its name: "I know that the Rio was called 'Putos.'...It is well-known by the name which has been given it" (J. J. Warner, land-grant case 232 ND). The name was probably fixed byWilliam Wolfskill,who named hisgrantRio de los Putoson May 24, 1842. In 1843 the name was used in the titles of three other land grants, in one of which the spellingPutasoccurs. In theStatutesof the early 1850s, in the Indian Reports, and in thePac. R.R.Reports,the spelling of the name is in complete confusion. The present version was applied to a town in 1853, was used in theStatutesof 1854, was made popular by the Bancroft maps, and finally was adopted by theUSGS.[7]
According to a map created byEugène Duflot de Mofras,a French naturalist and explorer, and published in Paris in 1844, Putah Creek was once known asYoung's River,named for the fur trapperEwing Young,who huntedbeaveron an expedition up Putah Creek toClear Lakeand on to theMendocino CountyCoast in March, 1833.[8]
The lower reaches of the creek used to sometimes be calledWalnut Bayou,in reference to the warm and sluggish water and the abundance of California Black Walnut trees on the banks.
Watershed and course

The creek originates fromspringson the east side ofCobb Mountainsouth of the town ofCobbin southwesternLake Countyand flows approximately 130 kilometres (81 mi) to Lake Berryessa. It descends eastward to the town ofWhispering Pines,where it turns southeast, parallellingState Route 175.It passes the town ofAnderson Springs,where it joins Bear Canyon Creek. North ofMiddletown,it curves counterclockwise aroundHarbin Mountain,merging in close succession with Dry Creek, Helena Creek, Crazy Creek, Harbin Creek, andBig Canyon Creek.From Harbin Mountain, it flows east again, joining Bucksnort Creek, then entersNapa Countyat a confluence with Hunting Creek about 11 mi (18 km) east of Middletown. In Napa County, the creek flows southeast, merging with Butts Creek just before it empties intoLake Berryessa,and the Monticello Dam.
Downstream ofMonticello Dam,on the southeastern corner of the lake, Putah Creek leaves Napa County and becomes the boundary betweenYolo CountyandSolano Countyflowing about 13 kilometres (8.1 mi) to the Putah Diversion Dam (PDD), where most of water flows are diverted south through the Putah South Canal to users inSolano County.In this section the creek offers excellent fishing opportunities year round.California Department of Fish and Wildliferegulations require "catch and release" in this section of the stream, as well as the use of artificial lures with barbless hooks.[9]TheCalifornia Office of Environmental Health Hazard Assessment(OEHHA) has developed a safe eating advisory for fish caught in Putah Creek based on levels of mercury orPCBsfound in local species.[10]Stormwater runoff from a nearby Superfund site formally known as the Laboratory for Energy-Related Health Research (LEHR), has shown elevated levels of Mercury reaching 500 ng/L entering Putah Creek. While the site has been decommissioned since the late 1980s and federally listed as a National Priority Superfund site by the EPA in 1994, the amount of contamination to the soil, groundwater aquifer, and nearby Putah Creek, continue to be a hazard to the area. This concentration of mercury in Putah creek creates health risks for anything that may eat the fish, as thebioaccumulationof mercury found in the fish passes along the food web to birds and potentially humans.[11]The stream continues east alongState Route 128,receivingPleasants Creek[12]before arriving atLake Solanowhere the Putah Diversion Dam diverts flows to the Putah South Canal, carrying water to the residents of Vallejo.
Below Lake Solano, Putah Creek flows 37 kilometres (23 mi) before reaching theYolo Bypassand by that artificial route, to the Sacramento River. In this section, Putah Creek first receives McCune Creek, then its last tributary, Dry Creek. After the Dry Creek confluence it passes through the town ofWintersto reachInterstate 505.From there Putah Creek channel continues eastward, parallelling Putah Creek Road to Stevenson Bridge Road. Putah Creek used to flow near downtown Davis in what is now the UC Davis Arboretum channel, but early settlers redirected the creek south of Davis in 1871, and in the late 1940s the Army Corps of Engineers added levees to what is now the South Fork Putah Creek.[13][14]A few miles east ofDavis,the county line turns south, but the South Fork Putah Creek continues eastward, passing south of Davis to feed into the Yolo Bypass about a quarter mile (400 m) west of theSacramento Deep Water Channel.
Dams and diversions
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/f/ff/Monticello_Dam.gif/220px-Monticello_Dam.gif)
Monticello Dam,aconcretearch dam, is the only major storage dam on the creek. It formsLake Berryessa,which has a capacity of 1,602,000 acre-feet (1.976×109m3), making it one of the largest reservoirs in the state of California. The dam and lake are part of theUnited States Bureau of Reclamation's Solano Project and was completed in 1957.[15]The project's purpose is to provide water for irrigation, though it also supplies municipal and industrial water to major cities inSolano County.About 32,000 acre-feet (39,000,000 m3) is provided by the project annually. An 11 MWhydroelectricplant generates electricity for the Solano Irrigation District, which owns and operates the dam.
The Putah Diversion Dam, or PDD, also constructed in 1957, diverts water into Putah South Canal about 6 miles (9.7 km) downstream of Monticello Dam. The dam is a gated concreteweirstructure with an earth-fill embankment wing. It creates the smallLake Solano,which has a capacity of only 750 acre-feet (930,000 m3). Thecanalis entirely concrete-lined except for a mile (1.6 km) of pipe called the Putah South Pipeline. Most of the lands are below the level of the canal and are served bygravity.Lands above pump water straight from the canal. The canal ends at Terminal Dam, which is made from earth-fill. The dam forms a small 119 acre-foot (147,000 m3) reservoir called Solano Lake. This reservoir suppliesdrinking waterto the city ofVallejo.Most of the canal is operated by Solano Irrigation District, including its headworks.
Ecology
[edit]Steelhead trout(coastal rainbow trout) (Oncorhynchus mykiss irideus) andChinook salmon(Oncorhynchus tshawytscha) continue to survive in Putah Creek. Although theseanadromoussalmonidscannot pass the Putah Diversion Dam, stream resident rainbow trout (the landlocked form of steelhead trout) continue to thrive above Monticello Dam in the upper headwaters and grow to large size in the first few miles directly below the dam.[16]
The ecological centerpiece of the 2000 Putah Creek Accord mandated flow releases from the Putah Diversion Dam intended to secure spawning and rearing flows for spring-spawning native fishes with a natural flow regime of higher winter and spring flows, with lower summer and fall flows, but mandated sufficient perennial flow to support rearing salmonids. The Accord mandated a short three-day pulse to occur between 15 February and 31 March to initiate spawning behavior, followed by a month-long release of elevated flows. Further, the Accord established a schedule of monthly baseline flows designed to maintain continuouslotic(flowing) conditions year-round from the PDD to the Yolo Bypass. In December 2014, the California Fish and Game Commission designated Putah Creek a "Wild Trout Water" and efforts by citizen groups to restore the creek resulted in increased Chinook salmon rearing in the lower watershed.[17]The natural flow regimes simulated by releases from the dams has restored native fishes while suppressing non-native fishes, the latter best adapted to warmer water and stagnant conditions. By increasing releases briefly in winter/spring and allowing much lower flows in late summer/fall, there has been little impact on overall water availability for diversion to agriculture and residents.[5]
An interesting study of the Putah Creek watershed from a bioregional perspective can be found in "Lifeplace: Bioregional Thought and Practice" by Robert L. Thayer[18]
"Green River"
[edit]Putah Creek is also known as the Green River due to the buildup of algae and vascular plants in the late summer.[citation needed]Putah Creek is the subject of theCreedence Clearwater Revivalsong "Green River"and served as a childhood vacation spot forJohn Fogerty.[19][20][21]
