SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUltBIA RIVER BASIN, 1938 SCOPE OF WORK This volume is one of a series of 14 reports presenting results of measurements of stage and flow made on streams, lakes, and reservoirs in the United States during the water year ending September 30, 1938. The work was begun in 1888 in connection with special studies relating to irrigation. Measurements of stream flow have been made at about 7,800 points in the United States and also at many points in Alaska and the Hawaiian Islands. In July 1938, 3,830 gaging stations were being maintained by the Geological Survey and cooperating organizations. Many miscellaneous discharge measurements were made at other points. In the execution of the work many State and private organizations have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgments for cooper ation of the first kind are made in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 9. DEFINITION OF TERMS The units in which stream-flow data are presented in this report and other terms used herein are defined as follows: "Second-feet" is an abbreviation for "cubic feet per second." A second-foot is the rate of discharge of water flowing in a channel when the cross-sectional area is 1 square foot and the average velocity is 1 foot per second. "Second-feet per square mile" is the average number of cubic feet of water flowing per second from each square mile of area drained, on the assumption that the run-off is dis tributed uniformly both as regards time and area. "Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly distributed on its surface. It is used for comparing run-off with rainfall, which is usually expressed in inches. An "acre-foot", equivalent to 43,560 cubic feet, is the quantity of water required to cover an acre to the depth of 1 foot. The term is commonly used in connection with stor age for irrigation. "Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and represents a run-off of 0.0372 inches from one square mile. "Stage-discharge relation" is an abbreviation for the term "relation of gage height to discharge." "Control" is a term used to designate the natural section or reach of the channel or artificial structure below the gage which determines the stage-discharge relation at the gage. EXPLANATION OF DATA The base data collected at gaging stations consist of records of stage, measurements of discharge, and general information used to supplement the gage heights and discharge 1 2 EXPLANATION OF DATA measurements in determining the daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a con tinuous record of the fluctuations. Measurements of discharge are made with a current meter by the general methods outlined in standard textbooks on the measurement of river discharge. Typical gaging stations, equipped with water-stage recorder and measuring cable and car, are shown on plate 1. Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily gage height to these rating tables gives the daily discharge, from which the monthly and yearly mean discharge are computed. The data presented for each gaging station in the area covered by this report usually comprise a description of the station, a table showing the daily discharge of the stream, and a table of monthly and yearly discharge and run-off. Skeleton rating tables are pub lished except for those stations whose daily discharge for the greater part of the year was determined by the shifting-control method, the slope method, or other special methods. The description of the station gives the type of gage, its latitude and longitude de termined from the best available maps, and information in regard to diversions that decrease the flow at the gage, artificial regulation from pondage or storage, and the accuracy of the records. Under ''Average discharge" is given the average discharge for the number of years indicated. It is given only for stations for which there are 10 or more complete years of record. Information under "Extremes" gives the maximum discharge and gage height; the minimum discharge if there is little or no regulation; the minimum daily discharge if there is extensive regulation, and also the minimum discharge if use ful; and the minimum gage height except when it is of no importance. Unless otherwise qualified, the maximum discharge corresponds to the crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the time of the crest. Likewise the minimum represents the lowest discharge, unless otherwise qualified. The peak discharge for the year with the time of its occurrence is given below the table of monthly discharge for some stations. Selected lower peaks are also given if the peak discharge exceeded the mean discharge for that day by more than 10 percent. This supplementary information is generally not given for stations having drainage areas of less than 10 square miles or more than 10,000 square miles. The table of daily discharge gives, for stations equipped with nonrecording gages, the discharge in second-feet corresponding to once-daily or the mean of twice-daily readings of the gage. For flashy floods the mean daily discharge is determined from gage-height graphs based on gage readings made once or twice daily or oftener, as stated in the sta tion description. For stations equipped with water-stage recorders the table gives the discharge corresponding to the mean daily gage height except for stations on streams sub ject to sudden or rapid fluctuation. For stations subject to such fluctuation the mean daily gage height may not indicate the true mean dally discharge, which must be obtained by averaging the discharge for Intervals of the day or by using the discharge Integrator, an Instrument for obtaining the mean daily discharge from a continuous gage-height graph and containing as an essential element the rating curve of the station. In the table of monthly discharge the column headed "Second-foot-days'1 gives the sum for each month of the figures for that month given in the table of daily discharge. The column headed "Maximum" gives the maximum daily discharge and not the discharge when the water surface was at crest height. Likewise, In the column headed "Minimum" the quantity GEOLOGICAL SURVEY WATER-SUPPLY PAPER 864 PLATE I A. ARTIFICIAL CONTROL, RECORDER HOUSE, AND MEASURING CABLE ON OLEN- TANGY RIVER, DELAWARE, OHIO. B. RECORDER HOUSE AND MEASURING CABLE ON KAWEAH RIVER, THREE RIVERS, CALIF. TYPICAL RIVER-MEASUREMENT STATIONS. PUBLICATION 2 given is the minimum daily discharge. The column headed "Mean" is the average flow in cubic feet per second during the month. ACCURACY OF FIELD DATA AND COMPUTED RESULTS The accuracy of stream-flow data depends primarily (1) on the permanency of the stage- discharge relation and (2) on the accuracy of observation of stage, measurements of flow, and interpretation of records. The station description gives a statement in regard to the general accuracy of the records. "Excellent" indicates that, in general, the daily records are accurate within 5 percent; "good", within 10 percent; "fair", within 15 percent; and "poor", within 20 percent or more. The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures showing discharge per so^iare mile and depth in inches may be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by inability to interpret the effect of artificial regu lation of the flow of the river above the station. "Second-feet per square mile" and "run-off in inches" are therefore not computed if such errors appear probable. The com putations are also omitted for stations on streams draining areas in which the annual rainfall is less than 20 inches. Many gaging stations on streams in the irrigated areas of the United States are situ ated above most of the diversions from those streams, so that the discharge recorded does not show the water supply available for further development, as prior appropriations below the station must first be satisfied. The table of monthly discharge gives a general idea of the flow at the station. The table of daily discharge allows more detailed studies of the variation in flow. It should be borne in mind, however, that the observations in each succeeding year may be expected to throw new light on data previously published, and that greater degrees of refinement in computations and records may be warranted with increased data and use of improved equipment.

Note.- The reports that contain reocrds after 1901 are given In the table on page 6. The table on the following page gives, by years and drainage basins, the numbers of the papers on surface water supply published from 1899 to 1938. The data for any par ticular station will, in general, be found in the reports covering the years during which the station was maintained. For example, the data from 1910 to 1920 for any station in the area covered by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 453, 473, and 503, which contain records for the Ohio River Basin for those years. The records at most of the stations discussed in these reports extend over a series of years. Miscellaneous measurements at many points other than regular gaging stations have been made each year and are published under "Miscellaneous discharge measurements" at the end of each report, the streams and points of measurement listed appearing in the same relative order as the streams and gaging stations in the body of the report. An index of the records obtained prior to 1904 has been published in Water-Supply Paper 119.

Note.- Records for stations listed in the above table were collected by the Oregon State engineer and published in bulletins of the State engineer as follows: For 1915-24, in Bulletin 7; for 1925-30, in Bulletin 8; and for 1931-36 (some to December) in Bulletin 9. Those for years subsequent to 1936 have not been published. Records on many canals, also, have been collected by the Oregon State engineer and the Bureau of Reclamation in connec tion with the operation of irrigation projects. The Soil Conservation Service began in 1938 to make studies of run-off from four areas of less than 15 acres each in the vicinity of Newberg, Oreg. The records are in the files of that organization. COOPERATION The work in the two States was done under cooperative agreements as follows: In Oregon, with the State engineer, Charles E. Stricklin; in Washington, with the Department of Conservation and Development, John Brooke Fink, director, and Charles J. Bartholet, super visor of hydraulics. Acknowledgments are also due to the Corps of Engineers, United States Army, and to the United States Weather Bureau for financial assistance in collecting records published herein. 10 DIVISION OF WORK Assistance in collecting records was also rendered by the following municipalities, organizations, corporations and individuals: In Oregon, by Deschutes, Jackson, Josephine, and Umatilla Counties; the cities of Eugene, McMlnnville, and Portland; The California Oregon Power Co., Pacific Power & Light Co., and Portland General Electric Co. In Washington by the city of Walla Walla, by Backus-Brooks Co., Inland Power & Light Co., and Northwestern Electric Co. Funds for the construction, repair, and improvement of gaging stations were allocated to the Geological Survey by the Federal Emergency Administration of Public Works. DIVISION OF WCRK The data for the stations in Oregon were collected and prepared for publication under the supervision of G. H. Canfield, district engineer, the work being done in collabora tion with Charles E. Stricklin, State engineer; in Washington, under the supervision of G. L. Parker, district engineer.

UMPQUA RIVER BASIN 141 Umpqua River near Elkton, Oreg. Location.- Staff gage, lat. 43°35', long. 123°33', in sec. 8, T. 23 S., R. 7 W., 4 miles south of Elkton. Zero of gage is approximately 95 feet above mean sea level (^-iver surveys of Geological survey). Drainage area.- 3,680 square miles. Records available.- October 1905 to September 1938 (prior to November 1908, incomplete). Average discharge.- 33 years, 7,143 second-feet. Extremes.- Maximum discharge during year, 116,000 second-feet Feb. 7 (gage height, 31.0 feet, from floodmark), from rating curve extended above 50.000 second-feet: minimum observed, 940 second-feet Sept. 23 (gage height, 1.20 feet). 1905-38: Maximum discharge, 172,000 second-feet Feb. 21. 1927 (gage height, 41.0 feet, from floodmark), from rating curve extended above 50,000 second-feet; minimum observed, 640 second-feet July 18, 1926 (gage height, 0.71 foot). Maximum stage known, about 45.5 feet sometime in 1861. Remarks.- Records good. Some diversions for irrigation from streams in South Umpqua River Basin, but low-water flow probably only slightly affected. Slight regulation by gates and racks of fish hatchery at Diamond Lake and by power plant at Winchester ordinarily does not affect discharge at this station. Gage read twice daily except during period July 10 to Sept. 3, when it was read once daily. Rating table, water year 1937-38 (gage height. In feet, and discharge.

WALLA RIVER BASIN, OREGON-WASHINGTON SPRINGS IN THE WALLA. WALLA RIVER BASIN, OREGON-WASHINGTON Ground-water overflow through numerous springs on the alluvial fan of the Walla Walla River near ' '.Iton and Freewater, Oreg., amounts to about 50,000 acre-feet a year. Dur ing the irrigation season, practically all the overflow is used to water crops on land that is not served by diversions from the river. The water users have a vital interest in the amount and variation of ground-water overflow, becuase (1) the acreage of crop land under irrigation in the basin is greater than can be watered from the Walla Walla River in years of small run-off, (2) the variation in spring discharge depends on the range in stream flow and the time and place of irrigation on the upper part of the fan, and (3) the springs are fed from a body of ground water from which irrigation wells also draw a considerable supply. A survey made in May and June, 1933, listed 57 springs or spring groups in the area.!/ In order to bring about a more effective use of the available water supply through a better understanding of the relation between surface- and ground-water supplies in the basin, ground-water levels and ground-water discharge are being measured periodically at representative wells and at the 18 principal springs or spring groups. A noteworthy feature of the springs is their occurrence in three parallel zones that are concentric about the apex of the alluvial fan. The inner zone is 3 to 3i miles downstream from Freewater and extends from the vicinity of Nicholas Spring, which is about half a mile east of the Walla Walla River at McCoy Bridge, to springs in the vicinity of Bugger Creek. Within this zone are fully three-fourths of the springs in the Walla Walla Basin. The intermediate and outer spring zones, each of which contains only a few springs, are about 2 miles and 4 miles, respectively, beyond the inner zone. Variations in the discharge of the springs follow largely fluctuations in elevation of the ground-water table. These fluctuations depend chiefly on the height of ground- water waves that are created by successive freshets in the Walla Walla River and that pass outward through the alluvial fan as the freshets wane, or they may be caused by deep infiltration of water applied to the land for irrigation and, in lesser degree, to deep infiltration of rainfall and to pumpage from irrigation wells.

SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUltBIA RIVER BASIN, 1938 SCOPE OF WORK This volume is one of a series of 14 reports presenting results of measurements of stage and flow made on streams, lakes, and reservoirs in the United States during the water year ending September 30, 1938. The work was begun in 1888 in connection with special studies relating to irrigation. Measurements of stream flow have been made at about 7,800 points in the United States and also at many points in Alaska and the Hawaiian Islands. In July 1938, 3,830 gaging stations were being maintained by the Geological Survey and cooperating organizations. Many miscellaneous discharge measurements were made at other points. In the execution of the work many State and private organizations have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgments for cooper ation of the first kind are made in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 9. DEFINITION OF TERMS The units in which stream-flow data are presented in this report and other terms used herein are defined as follows: "Second-feet" is an abbreviation for "cubic feet per second." A second-foot is the rate of discharge of water flowing in a channel when the cross-sectional area is 1 square foot and the average velocity is 1 foot per second. "Second-feet per square mile" is the average number of cubic feet of water flowing per second from each square mile of area drained, on the assumption that the run-off is dis tributed uniformly both as regards time and area. "Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly distributed on its surface. It is used for comparing run-off with rainfall, which is usually expressed in inches. An "acre-foot", equivalent to 43,560 cubic feet, is the quantity of water required to cover an acre to the depth of 1 foot. The term is commonly used in connection with stor age for irrigation. "Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and represents a run-off of 0.0372 inches from one square mile. "Stage-discharge relation" is an abbreviation for the term "relation of gage height to discharge." "Control" is a term used to designate the natural section or reach of the channel or artificial structure below the gage which determines the stage-discharge relation at the gage. EXPLANATION OF DATA The base data collected at gaging stations consist of records of stage, measurements of discharge, and general information used to supplement the gage heights and discharge 1 2 EXPLANATION OF DATA measurements in determining the daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a con tinuous record of the fluctuations. Measurements of discharge are made with a current meter by the general methods outlined in standard textbooks on the measurement of river discharge. Typical gaging stations, equipped with water-stage recorder and measuring cable and car, are shown on plate 1. Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily gage height to these rating tables gives the daily discharge, from which the monthly and yearly mean discharge are computed. The data presented for each gaging station in the area covered by this report usually comprise a description of the station, a table showing the daily discharge of the stream, and a table of monthly and yearly discharge and run-off. Skeleton rating tables are pub lished except for those stations whose daily discharge for the greater part of the year was determined by the shifting-control method, the slope method, or other special methods. The description of the station gives the type of gage, its latitude and longitude de termined from the best available maps, and information in regard to diversions that decrease the flow at the gage, artificial regulation from pondage or storage, and the accuracy of the records. Under ''Average discharge" is given the average discharge for the number of years indicated. It is given only for stations for which there are 10 or more complete years of record. Information under "Extremes" gives the maximum discharge and gage height; the minimum discharge if there is little or no regulation; the minimum daily discharge if there is extensive regulation, and also the minimum discharge if use ful; and the minimum gage height except when it is of no importance. Unless otherwise qualified, the maximum discharge corresponds to the crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the time of the crest. Likewise the minimum represents the lowest discharge, unless otherwise qualified. The peak discharge for the year with the time of its occurrence is given below the table of monthly discharge for some stations. Selected lower peaks are also given if the peak discharge exceeded the mean discharge for that day by more than 10 percent. This supplementary information is generally not given for stations having drainage areas of less than 10 square miles or more than 10,000 square miles. The table of daily discharge gives, for stations equipped with nonrecording gages, the discharge in second-feet corresponding to once-daily or the mean of twice-daily readings of the gage. For flashy floods the mean daily discharge is determined from gage-height graphs based on gage readings made once or twice daily or oftener, as stated in the sta tion description. For stations equipped with water-stage recorders the table gives the discharge corresponding to the mean daily gage height except for stations on streams sub ject to sudden or rapid fluctuation. For stations subject to such fluctuation the mean daily gage height may not indicate the true mean dally discharge, which must be obtained by averaging the discharge for Intervals of the day or by using the discharge Integrator, an Instrument for obtaining the mean daily discharge from a continuous gage-height graph and containing as an essential element the rating curve of the station. In the table of monthly discharge the column headed "Second-foot-days'1 gives the sum for each month of the figures for that month given in the table of daily discharge. The column headed "Maximum" gives the maximum daily discharge and not the discharge when the water surface was at crest height. Likewise, In the column headed "Minimum" the quantity GEOLOGICAL SURVEY WATER-SUPPLY PAPER 864 PLATE I A. ARTIFICIAL CONTROL, RECORDER HOUSE, AND MEASURING CABLE ON OLEN- TANGY RIVER, DELAWARE, OHIO. B. RECORDER HOUSE AND MEASURING CABLE ON KAWEAH RIVER, THREE RIVERS, CALIF. TYPICAL RIVER-MEASUREMENT STATIONS. PUBLICATION 2 given is the minimum daily discharge. The column headed "Mean" is the average flow in cubic feet per second during the month. ACCURACY OF FIELD DATA AND COMPUTED RESULTS The accuracy of stream-flow data depends primarily (1) on the permanency of the stage- discharge relation and (2) on the accuracy of observation of stage, measurements of flow, and interpretation of records. The station description gives a statement in regard to the general accuracy of the records. "Excellent" indicates that, in general, the daily records are accurate within 5 percent; "good", within 10 percent; "fair", within 15 percent; and "poor", within 20 percent or more. The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures showing discharge per so^iare mile and depth in inches may be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by inability to interpret the effect of artificial regu lation of the flow of the river above the station. "Second-feet per square mile" and "run-off in inches" are therefore not computed if such errors appear probable. The com putations are also omitted for stations on streams draining areas in which the annual rainfall is less than 20 inches. Many gaging stations on streams in the irrigated areas of the United States are situ ated above most of the diversions from those streams, so that the discharge recorded does not show the water supply available for further development, as prior appropriations below the station must first be satisfied. The table of monthly discharge gives a general idea of the flow at the station. The table of daily discharge allows more detailed studies of the variation in flow. It should be borne in mind, however, that the observations in each succeeding year may be expected to throw new light on data previously published, and that greater degrees of refinement in computations and records may be warranted with increased data and use of improved equipment.

The data for any par ticular station will, in general, be found in the reports covering the years during which the station was maintained. For example, the data from 1910 to 1920 for any station in the area covered by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 453, 473, and 503, which contain records for the Ohio River Basin for those years. The records at most of the stations discussed in these reports extend over a series of years. Miscellaneous measurements at many points other than regular gaging stations have been made each year and are published under "Miscellaneous discharge measurements" at the end of each report, the streams and points of measurement listed appearing in the same relative order as the streams and gaging stations in the body of the report. An index of the records obtained prior to 1904 has been published in Water-Supply Paper 119.

Note.- Records for stations listed in the above table were collected by the Oregon State engineer and published in bulletins of the State engineer as follows: For 1915-24, in Bulletin 7; for 1925-30, in Bulletin 8; and for 1931-36 (some to December) in Bulletin 9. Those for years subsequent to 1936 have not been published. Records on many canals, also, have been collected by the Oregon State engineer and the Bureau of Reclamation in connec tion with the operation of irrigation projects. The Soil Conservation Service began in 1938 to make studies of run-off from four areas of less than 15 acres each in the vicinity of Newberg, Oreg. The records are in the files of that organization. COOPERATION The work in the two States was done under cooperative agreements as follows: In Oregon, with the State engineer, Charles E. Stricklin; in Washington, with the Department of Conservation and Development, John Brooke Fink, director, and Charles J. Bartholet, super visor of hydraulics. Acknowledgments are also due to the Corps of Engineers, United States Army, and to the United States Weather Bureau for financial assistance in collecting records published herein. 10 DIVISION OF WORK Assistance in collecting records was also rendered by the following municipalities, organizations, corporations and individuals: In Oregon, by Deschutes, Jackson, Josephine, and Umatilla Counties; the cities of Eugene, McMlnnville, and Portland; The California Oregon Power Co., Pacific Power & Light Co., and Portland General Electric Co. In Washington by the city of Walla Walla, by Backus-Brooks Co., Inland Power & Light Co., and Northwestern Electric Co. Funds for the construction, repair, and improvement of gaging stations were allocated to the Geological Survey by the Federal Emergency Administration of Public Works. DIVISION OF WCRK The data for the stations in Oregon were collected and prepared for publication under the supervision of G. H. Canfield, district engineer, the work being done in collabora tion with Charles E. Stricklin, State engineer; in Washington, under the supervision of G. L. Parker, district engineer.

UMPQUA RIVER BASIN 141 Umpqua River near Elkton, Oreg. Location.- Staff gage, lat. 43°35', long. 123°33', in sec. 8, T. 23 S., R. 7 W., 4 miles south of Elkton. Zero of gage is approximately 95 feet above mean sea level (^-iver surveys of Geological survey). Drainage area.- 3,680 square miles. Records available.- October 1905 to September 1938 (prior to November 1908, incomplete). Average discharge.- 33 years, 7,143 second-feet. Extremes.- Maximum discharge during year, 116,000 second-feet Feb. 7 (gage height, 31.0 feet, from floodmark), from rating curve extended above 50.000 second-feet: minimum observed, 940 second-feet Sept. 23 (gage height, 1.20 feet). 1905-38: Maximum discharge, 172,000 second-feet Feb. 21. 1927 (gage height, 41.0 feet, from floodmark), from rating curve extended above 50,000 second-feet; minimum observed, 640 second-feet July 18, 1926 (gage height, 0.71 foot). Maximum stage known, about 45.5 feet sometime in 1861. Remarks.- Records good. Some diversions for irrigation from streams in South Umpqua River Basin, but low-water flow probably only slightly affected. Slight regulation by gates and racks of fish hatchery at Diamond Lake and by power plant at Winchester ordinarily does not affect discharge at this station. Gage read twice daily except during period July 10 to Sept. 3, when it was read once daily. Rating table, water year 1937-38 (gage height. In feet, and discharge.

WALLA RIVER BASIN, OREGON-WASHINGTON SPRINGS IN THE WALLA. WALLA RIVER BASIN, OREGON-WASHINGTON Ground-water overflow through numerous springs on the alluvial fan of the Walla Walla River near ' '.Iton and Freewater, Oreg., amounts to about 50,000 acre-feet a year. Dur ing the irrigation season, practically all the overflow is used to water crops on land that is not served by diversions from the river. The water users have a vital interest in the amount and variation of ground-water overflow, becuase (1) the acreage of crop land under irrigation in the basin is greater than can be watered from the Walla Walla River in years of small run-off, (2) the variation in spring discharge depends on the range in stream flow and the time and place of irrigation on the upper part of the fan, and (3) the springs are fed from a body of ground water from which irrigation wells also draw a considerable supply. A survey made in May and June, 1933, listed 57 springs or spring groups in the area.!/ In order to bring about a more effective use of the available water supply through a better understanding of the relation between surface- and ground-water supplies in the basin, ground-water levels and ground-water discharge are being measured periodically at representative wells and at the 18 principal springs or spring groups. A noteworthy feature of the springs is their occurrence in three parallel zones that are concentric about the apex of the alluvial fan. The inner zone is 3 to 3i miles downstream from Freewater and extends from the vicinity of Nicholas Spring, which is about half a mile east of the Walla Walla River at McCoy Bridge, to springs in the vicinity of Bugger Creek. Within this zone are fully three-fourths of the springs in the Walla Walla Basin. The intermediate and outer spring zones, each of which contains only a few springs, are about 2 miles and 4 miles, respectively, beyond the inner zone. Variations in the discharge of the springs follow largely fluctuations in elevation of the ground-water table. These fluctuations depend chiefly on the height of ground- water waves that are created by successive freshets in the Walla Walla River and that pass outward through the alluvial fan as the freshets wane, or they may be caused by deep infiltration of water applied to the land for irrigation and, in lesser degree, to deep infiltration of rainfall and to pumpage from irrigation wells.
