Big Butte Creek is a 12-mile-long (19 km)tributary of theRogue River in the U.S. state ofOregon. Itdrains approximately 245 square miles (635 km2) ofJackson County. Its two forks, the North Fork and the South Fork, both begin high in theCascade Range nearMount McLoughlin. Flowing predominantly west, they meet near the city ofButte Falls. Themain stem flows generally northwest until it empties into the Rogue River nearMcLeod, about one mile southwest of William L. Jess Dam andLost Creek Lake.
Big Butte Creek'swatershed was originally settled over 8,000 years ago by humans, and in historical times by theKlamath,Upper Umpqua, andTakelma tribes of Native Americans. In theRogue River Wars of the 1850s, most of the Native Americans were either killed or forced ontoIndian reservations. The first white settlers arrived in the 1860s, naming the creek after Snowy Butte[a], an early name for Mount McLoughlin. In the late 19th century, the watershed was primarily used for agriculture and logging. The small city of Butte Falls wasincorporated in 1911, and remains the onlyincorporated municipality within the watershed's boundaries.
Big Butte Springs, located in the watershed, provides clean drinking water to more than 115,000 residents of theRogue Valley. It emits over 26 million US gallons (98,000,000 L) of water per day. Water from Big Butte Creek is also diverted forirrigation at several other locations.
The water quality of the Big Butte Creek watershed is generally high, and it supports several species oftrout andsalmon. The watershed is also home to more than 152 species of birds, 63 species of mammals, 19 species of reptiles, and numerous plants. The Poverty Flats region was designated anArea of Critical Environmental Concern by theBureau of Land Management in 1995 to protect several rare species of plants.
Big Butte Creek begins in theCascade Range nearButte Falls. It flows generally northwest over approximately 12 miles (19 km) to its confluence with the Rogue River.[2][5] The two main forks of Big Butte Creek, the North Fork and the South Fork, merge at 2,244 feet (684 m) above sea level,[b] while the creek's mouth is located at an elevation of 1,562 feet (476.1 m).[1]
The North Fork's headwaters are located on the slopes of the 6,207-foot-tall (1,892 m)Rustler Peak.[5][7] It flows southwest, receiving many small tributaries such as Jackass, Eighty Acre, and Friese creeks. Turning west, it flows just north of Butte Falls before merging with the South Fork.[5]
The South Fork begins at the confluence of two of its tributaries, Twincheria and Rancheria creeks. It flows southwest, receiving Fourbit Creek on theleft.[5] Fourbit Creek begins near Mount McLoughlin, where massivefaults may allow water to seep into it from nearbyFourmile Lake in theKlamath River watershed.[3] The South Fork turns west and receives Willow Creek on the left. Big Butte Springs are located on Willow Creek, and the Medford Aqueduct, which carries drinking water to cities in the Rogue Valley, parallels the South Fork from there all the way to Butte Falls. The South Fork flows over the 15-foot-tall (4.6 m) Butte Falls—the nearby city's namesake—and merges with the North Fork about 1 mile (1.6 km) downstream.[2][5][8]
Big Butte Creek travels northwest, gathering McNeil Creek on the left and Clark Creek on theright, along with many other minor tributaries.[5] This region contains many Class II and III rapids, as rated on theInternational Scale of River Difficulty.[8] The stream is crossed by Cobleigh Road atriver mile (RM) 9.5 or river kilometer (RK) 15,[9] and Netherlands Road at RM 3 (RK 4.8).[10] About 0.6 miles (1 km) before its mouth, Big Butte Creek cascades over Crowfoot Falls and is crossed by Crowfoot Road.[11][12] It then flows into the Rogue River 155 miles (249 km) from its mouth at the Pacific Ocean.[12] Big Butte Creek's mouth is about one mile southwest of William L. Jess Dam, andOregon Route 62 passes just north of it.[5][12]
TheUnited States Geological Survey monitors the flow of Big Butte Creek at three differentstream gauges: two on the South Fork, and one on themain stem. Both South Fork gauges were shut down in 1991, but the gauge located near the mouth of Big Butte Creek continues to operate. The main stem often discharges less water than the South Fork alone in the summer months because of numerous diversions.[3]

Big Butte Creek drains approximately 245 square miles (635 km2) ofsouthern Oregon. Elevations range from 1,562 feet (476.1 m) at the creek's mouth to 9,495 feet (2,894 m) at the summit of Mount McLoughlin, with an average of 3,528 feet (1,075 m).[19][20] About 56 percent isfederally owned by the Bureau of Land Management and theUnited States Forest Service, 44 percent is privately owned, and a small fraction belongs to the City ofMedford.[19]
The Big Butte Creek watershed experiences aMediterranean climate. Temperatures range from 10 °F (−12 °C) in the winter to 100 °F (38 °C) in the summer.[3][21][22]Precipitation averages between 35 and 80 inches (890 and 2,000 mm) annually. Most precipitation occurs between November and March.[3][21][22] Nine percent of the watershed'ssurface runoff is collected from rain, 35 percent from rain on snow, and 56 percent from snow.[19] The watershed contains the largestgroundwater source in the entire Rogue River basin; one major outlet is at Big Butte Springs.[3]
The watershed is split into two geographic regions: the High Cascades and the Western Cascades, bothvolcanic in origin. The Western Cascades compose the western two thirds of the watershed. This region is highly eroded, being between 17 and 38 million years old. Its unstable slopes are primarily made ofpyroclastic rock. Due to the rock's high ability to absorb moisture,earthflows are common. The High Cascades are much younger, around three to seven million years old. Mount McLoughlin is the most prominent High Cascade volcano in the watershed, last erupting between 20,000 and 15,000 years ago.[23]Basalt andandesite are the most common rock types in this region.[3][19]
Nearby watersheds include Little Butte Creek to the south, smallKlamath River tributaries such as Fourmile Creek to the east, theSouth Fork Rogue River to the east and north, and minor tributaries of the Rogue River including Reese and Indian creeks to the west.[5]
Some of the most common trees that grow in the Big Butte Creek watershed include four species offir, two species ofpine,incense cedar, andwestern hemlock. Theunderstory contains plants such asPacific yew,Pacific madrone,chinquapin, andvine maple. Severalinvasive species have been reported in the Big Butte Creek watershed, such asKentucky bluegrass,common bent,drooping brome, andredtop. The spread of these species is most likely due toovergrazing.[3] Sensitive species that grow in the watershed includeHowell's yampah,Egg Lake monkeyflower,clustered lady's slipper,green-flowered ginger,Mount Mazama collomia, andDetling's microseris.[3][22]Mallow andpopcorn flower have also been discovered inriparian zones. The Poverty FlatsArea of Critical Environmental Concern (ACEC) is home to several rare species of plants, includingBellinger's meadowfoam, Howell's yampah, andRocky Mountain woodsia.[21]
Over 152 species of birds are known or suspected to live in the Big Butte Creek watershed,[21][22] including thenorthern goshawk and thenorthern spotted owl, avulnerable species.Bald eagles nest around Willow Lake.[3][21][22]Amphibians such as the vulnerableOregon spotted frog and thenear threatenedCascades frog inhabit some regions of the watershed.[21][22]Black-tailed deer,Roosevelt elk,cougars, andblack bears are the most common of the 63 species of mammals found in the watershed.Fishers andAmerican martens have also been spotted. Thegray wolf and the vulnerablegrizzly bear once lived in the watershed, but are now consideredextirpated. Nineteen species of reptiles live in the area. Other sensitive species include thewolverine, thewestern pond turtle, thesandhill crane, andTownsend's big-eared bat.[3]
Rainbow trout,chinook andcoho salmon, andPacific Lamprey are the most commonanadromous fish that inhabit Big Butte Creek.[19][21][22] They travel as far as Butte Falls, sometimes passing over it during high flows.[19][22] Because of the cold, sterile conditions of the water and the difficulty of jumping over theButte Creek waterfall, streams above Butte Falls have very low populations of anadromous fish.[3] Native, resident fish in this area includecoastal cutthroat and rainbow trout.[3][19] Willow Lake containslargemouth bass and rainbow, cutthroat, andbrook trout.[3] Overall, the number of fish in the Big Butte Creek watershed has declined in recent years, possibly due to the clearing of riparian zones and rising water temperatures.[21][22]

Humans have lived in the Big Butte Creek area for at least 8,000 years.[3] TheKlamath,Upper Umpqua,Takelma, andLatgawa tribes of Native Americans inhabited the watershed until they were driven out in theRogue River Wars of the 1850s.[3][21] On Christmas Eve, December 24, 1855, Captain E. A. Rice along with 34 other men attacked a Native American encampment near the creek's mouth. Eighteen Native American men were killed, all the women and children were captured, and the camp was burned to the ground.[24] Most were relocated toIndian reservations. Non-indigenoussettlers first arrived in the early 1860s, and agriculture,ranching, and logging industries quickly developed.[3][21] Big Butte Creek was named by early settlers for its close proximity to Mount McLoughlin (also known as Snowy Butte[a]), as was nearbyLittle Butte Creek.[25]
In 1904, a water-poweredsawmill was constructed at Butte Falls. The town of Butte Falls was established in 1906, andincorporated in 1911.[3][19][22] The Pacific and Eastern Railway was constructed to Butte Falls in 1910.[3][22] Butte Falls also receivedwater rights to Ginger Springs, providing high quality drinking water for the town.[19][22]
The Cat Hill Burn destroyed 30,000 acres (120 km2) of forest on Rustler Peak in 1910.[3][22] In 1915, the Eagle Point Irrigation Canal was constructed, diverting approximately 100 cubic feet per second (2.83 m3/s) of water forirrigation in the Little Butte Creek watershed.[19][20] The canal begins just below Butte Falls.[3] The Butte Falls Fish Hatchery was also constructed in 1915.[22][26] Originally, the hatchery impounded water from Ginger Creek, however in 1923 a canal was built transferring 15.5 cubic feet per second (0.439 m3/s) of water from the South Fork of Big Butte Creek.[19][22][26] The Medford Aqueduct, a 31-inch-wide (79 cm) pipeline, was constructed in 1927. It delivers about 40 cubic feet per second (1.1 m3/s) of drinking water from Big Butte Springs south to theBear Creek watershed.[3][27][28] In 1951, a second pipeline was added, and Willow Dam was constructed, creating Willow Lake.[28] The springs serve over 115,000 customers throughout theRogue Valley.[29]
Loggers felled massive amounts of forest in the 1920s and 1930s.Reforestation efforts began in the 1940s because natural regeneration could not keep pace with the rate of logging. In 1962, theColumbus Day Storm knocked many more large trees to the ground. Today,old-growth forest covers only about five percent of the watershed.[3]
In 1995, the Poverty Flats region was designated an Area of Critical Environmental Concern (ACEC) by theBureau of Land Management. Located about 3.5 miles (5.6 km) west of Butte Falls, the ACEC is home to several rare species of plants. It was fenced off in 1996 to protect the area from roaming cattle.[21]
The Butte Falls Fish Hatchery was scheduled to be closed by theOregon Department of Fish and Wildlife in July 2009 as part of a statewide effort to decrease the department's budget,[30] but on July 3 it was announced that the hatchery would continue to operate with only one employee.[31] However, the hatchery was closed permanently in October 2010.[32]
A 160-foot (49 m) portion of the Eagle Point Irrigation Canal failed on October 2, 2011, sending 86 cubic feet per second (2.4 m3/s) of muddy water down a hillside, across a road, and into lower Big Butte Creek, a vital salmon spawning area. A stream gauge on the Rogue River about 15 miles (24 km) downstream reportedturbidity levels twenty times higher than before the breach.[33][34] The canal was repaired by October 28.[34]
TheOregon Department of Environmental Quality (DEQ) has monitored Big Butte Creek for eight different parameters that affect water quality: temperature,oxygen saturation,pH,nutrients, bacteria, chemical contaminants such aspesticides and metals,turbidity, andalkalinity. Streams that exceed the standard level are placed on the DEQ 303d list in accordance with theClean Water Act. About 54.2 miles (87.2 km) of the streams in the Big Butte Creek watershed were listed on the 2004/2006 DEQ 303d list. The entire main stem exceeded the standard level for temperature, oxygen saturation, andE. coli, a type of bacteria. The lower 13.9 miles (22.4 km) of the North Fork were listed for high temperature, along with many other minor tributaries. The South Fork was not listed, although some of its tributaries were.[19]
Overall, water quality in the Big Butte Creek watershed is generally high, however road construction and logging can cause severe erosion, leading to high levels ofsedimentation and turbidity. The Willow Creek region often experiences high turbidity, but Willow Lake traps the sediment before it can travel downstream. Big Butte Springs provides clean water that requires minimal treatment to meet water quality standards. Water from the springs has very little chemical pollution, low turbidity, and temperatures averaging between 44 and 46 °F (6.7 and 7.8 °C).[3]
Popular recreational activities in the Big Butte Creek watershed include hunting, camping, hiking, andhorseback riding.[3][21][22] Many tourists also come to sight-see.[22] The most heavily used trail in the area is the Blue Canyon Trail, leading to theSky Lakes Wilderness, and ultimately the largerPacific Crest Trail.[5][22] The city of Butte Falls has organized the Butte Falls Discovery Loop Tour, a half-day-long drive through theRogue River – Siskiyou National Forest. The loop starts in Butte Falls, and has several stops for hiking and viewing the landscape, including Mount McLoughlin.[35]
Water recreation on Willow Lake includes boating, swimming, fishing, andwaterskiing. Fishing is also popular in other streams, especially Fourbit Creek.[3][22]Cross-country skiing andsnowmobiling are popular in the winter.[3]
