FOt OUBOOH STREAMS By A* M» INTRODUCTION Practically all water -temperature data col lee tad through September 30, 1962, by varioua agendas, both public and private, are presented herein. Only those racords with ao fav observations as to ba of ao significant valua have beau omitted. Through the 1962 water year, tha Geological Survey haa collected up to 16 years of spot-observation data (periodic a*aeur events) at more than 200 sices and 1 or coore years of thermograph records at 55 sites. Some thermograph records that began as early as 1950 are still beii^ collected end wnre than 55 records are being collected currently. However* about 2S of these records were begun duriag the awjBeir of 1963 aw) are therefore not included in this compilation. Through 1962, other agencies have collected nore than 70 thermograph records and about as nany spot~ob«ervetion records. Many of the thermograph records, however, are only a few months to a year in length. ta, The thermograph records collected by the Geological Survey have bee* published through 1956 in the annual series of i»ter-supply papers, "Quality of Surface Waters of the United States". Beginning with records for 1962* the Geological Survey in Oregon is publishing thermograph records t along with discharge records for the same site* in the annual statewide report. The temperature records for 1959*61 will eventually be published in the annual water*supply papers on quality of water, but meanwhile this open- file compilation will serve to make available the monthly ftguraa of water temperature at thermograph sites. Most of the thermograph and spot-observation records collected by other ggmVcies have never bean published, and the same is true for all spot observations made by the Geological Survey, This compilation does not show daily temperatures or individual observations because their inclusion would greatly increase the siae of the report and because mean Monthly temperatures and Monthly extremes of temperature are believed to be of more significance* The report was prepared under the general supervision of R, B, Sander son. District Engineer, in charge of surface-water investigations in Oregon* E« H. Stoite assisted in the preparation of «anu*cript descriptions for the various observation sites. COOPERATION Financial assistance in the preparation of this report was furnished by? Oregon State Water Resources Board{ U.S. Bureau of Reclamation; U.S. Corps of Engineers; U.S. Public Health Service; and U.S. toil Conservatism Service. Some record* Included In this report were furnished by; U.S. Flah and Wildlife Service* Bureau of Coranecioel Fisheries; U.S* Corps of Engineers; Oregon State Flah Commission; Oregon State Game Commission*, Oregon State Sanitary Authority; city of Corvallls; city of Portland; Eugene Water and Elemtrie Board; Portland General Electric Co.; and Roseburg-Oresjom Water Corporatlea. EXPLAJSATION OF DATA Station DagcriptIons Bach water-temperature record la preceded by a short description in which is given location of the measuring site, the drainage area at the site (if kmowm), a eaort description of the records available, end a "Remarks" paragraph, If necessary. 1!he number preceding the Mew of the station la the compilation number. Theae numbers run from t to 381 and are also used to designate sites on plate 1 (In pocket), Numbers shown parenthetically after the name of the station designate Geological Survey gaging stations in accordance with the national mweberie^ system for such stations, AbeemoaY of this number SJSJSJM the site is other than a Geological Survey station. Location The tjeosuring-site location is described in several ways by latitude asji longitude; by township and range; by physical features such as tributary streams, highway bridges, and towns; end by miles above axwth, where that information is reedily available, Elver ileagga have for the sjeet pert been taken from the varloue basin indexes prepared by the Columbia Basin Inter-Agency Committee, Subcoaonittae on Hydrology. Only preliminary un checked figures for river mileage were available for the Rogue and Umpqua River basina, but these are believed to be reasonably accurate and subject ta> little Drainage Area Drainage-area figures were available for all sitea where datt were collected by the Geological Survey; tlstt aad fund* did net permit deter* miaation of drainage area at other sites. However, many of these other location* are betTUMB iitea for which drainage areas have been determined end, therefore, the drainage area* can be estijsated within rough limits. Water-Temperature Records Available ftiia paragraph indicates the type of record and the period for which it was obtained. For spot-observation records, the number of spot obser vation* made during the given period is listed and, where necessary, attention is called to any unusual distribution of the observations. In earn* instances, two or aore agencies collected records at the sane site, or practically the sane site, and sometimes for the same period or over lapping periods. Such records are listed under one station description. In some instances, the Geological Survey made spot observations over a long period of years and, in addition, obtained a thermograph record for a year or two. There» too, both records are given, but generally when tha thermograph record is at least 4 yeara in length, die spot-observation i record is omitted. Remarks In the "Remarks" paragraph* mention is mad* of regulation by reservoirs or pewrplants that could conceivably affect water temperature* Also, credit is given to the agency that furnlsbed the record; omission of such credit means that records vere obtained by the Geological Survey. Tablet of Water-Temperature Data The %mter temperatures shown for the varioua sites are In degrees Fahrenheit, Record* furnished by the State Sanitary Authority vere converted from the Geljine (centigrade) to the Fahrenheit scale for uniformity throughout. All tables are arranged In water-year form. The vater year begins October 1 and ends September 30* Water year 1959, for example, extends from October 1958 to September 1959. Thermograph Records For thermograph records, the maximum, miniraura, and Man vater temperatures are listed for each month of each year. These data are then summarised for each month for the period of record. If a thermograph record *as obtained prior to and subeequent to the construction of a reservoir immediately upstream, pertod-of-record means and extremes are computed for both periods to show the effect of the reservoir In some instances, short gaps in the record are fIliad through correlation with another thermograph record. Where this is dem*» a feotnote is used to designate the estimated temperatures and to shov which record wee used for correlation. >N Spot-Observation Records Where the spot observations are once dally or more frequent, the record la compiled Just as for the thermograph records. All the other «8 *V 'V-> spot ooservacions are generally maae every j or o we«Ks ena cnererore \L V/ V K it is not passible to compute observed onthiy MM omd extremea for mch aomth of each year./ fwo eote ofMonthly mjoans and extremoa ft>r the period of reared are shown, the "observed" asm and extremes are listed first, followed by the "adjusted" means and extremes. The individual spot observations thomaelves are not shown. A footnote to the table shows the thermograph record with which epot*»observations were correlated to obtain the adjusted figures. (See open-file report on "Correlation and Analysis of Meter-Temperature Data for Oregon Sti by A. M, Moore, 1964.) A fow records which include observations before and after the construction of an upstreox reservoir have been split into two periods to show the affect of the reservoir. Even though the spot observations wore (onorally not nade once each rao*th, correlation with a thermograph record would have permitted the it '' computation of adjusted means and extroooa at the spot observation site for oach month of each year for the period of record at the thermograph alto. Bowover, time and funds did not permit this. Also, period-ef- record aim and extremes probably are sufficient for moot purposes. flota that. In general, the "adjfriated" aeaa and tba gpot~observati.on
