It provides {{convert|26|e6USgal|L}} of high quality water per day.[2][3] The springs provide enough water to meet the needs of the valley for seven months of the year. During the remaining five months, water is pumped and treated from the Rogue River.[2] The springs provide water to over 115,000 customers.[9] Water qualityThe springs are fed by an {{convert|88|mi2|km2|adj=on}} watershed.[3] The water requires minimal treatment to meet water quality standards. The hardness of the springs' water has declined in recent years.[2] In 2007, the springs were tested in 120 different areas, exceeding federal standards in all of them.[4] Water temperatures average between {{convert|44|and|46|F|C|1}}. The springs have very little chemical pollution, and low turbidity. The flow of the springs remains steady throughout the year.[2] HistoryBeginning in 1908, Medford received drinking water from Fish Lake.[4][5] Several years later, the surrounding land was not cleared of debris when the Fish Lake dam was expanded. Soon, the woody debris rotted, and the water was determined undrinkable.[5] In 1923, the Medford Water Commission received water rights to {{convert|30|to|60|ft3/s|m3/s}} of water from Big Butte Springs. The Medford Aqueduct, a {{convert|31|in|cm|adj=on}} pipeline, was finished in 1927, transferring about {{convert|40|ft3/s|m3/s}} of drinking water to residents of the Bear Creek watershed.[5][6] In 1951, another pipeline was added.[5] References1. ^1 {{cite gnis|id=1137985|name=Big Butte Springs|entrydate=November 28, 1980|accessdate=November 15, 2013}} 2. ^1 2 3 4 5 {{cite web |url=http://www.blm.gov/or/districts/medford/plans/files/upper_big_butte_wa_acc.PDF |format=PDF |publisher=Rogue River National Forest |title=Upper Big Butte Watershed Analysis |date=December 1995 |accessdate=February 2, 2010}} 3. ^1 2 {{cite book |first1=Angie |last1=Fletcher |first2=Susan |last2=Davis |first3=Grant |last3=Pike |title=Water utility/agricultural alliances |publisher=American Water Works Association |year=2005 |isbn=978-1-58321-375-9 |url=https://books.google.com/books?id=EfrnVSzsWrIC&lpg=PP1&pg=PA143#v=onepage&q=&f=false |page=143}} 4. ^1 2 {{cite news |first=Troy |last=Heie |title=Bottled vs. tap water |work=Mail Tribune |location=Medford, Oregon |url=http://www.mailtribune.com/apps/pbcs.dll/article?AID=/20080623/OREGONHEALTHYLIVING/806230310 |date=June 23, 2008 |accessdate=February 5, 2010}} 5. ^1 2 3 {{cite web |date=March 2002 |title=Water for Our Community |url=http://rvtv.roguedatavault.net/asxgen/medford/videos/water.wmv |format=WMV |publisher=Southern Oregon University |accessdate=February 5, 2010 |deadurl=yes |archiveurl=https://web.archive.org/web/20110724043302/http://rvtv.roguedatavault.net/asxgen/medford/videos/water.wmv |archivedate=July 24, 2011 |df= }} 6. ^ {{cite web |url=http://www.roguebasinwatersheds.org/Files/URWA_Chapter1_FINAL%2012-15-06.pdf |format=PDF |publisher=Upper Rogue Watershed Association |title=Upper Rogue Watershed Assessment |date=December 16, 2006 |accessdate=February 5, 2010}} 2 : Springs of Oregon|Bodies of water of Jackson County, Oregon |
