Water-quality Data for the South Umpqua River Basin, Oregon, 1990-92By Chauncey W. Anderson, Dwight Q. Tanner, and Douglas B. Lee
ABSTRACT
Data are presented from a study of algal and nutrient dynamics in the South Umpqua River Basin in southwestern Oregon during summer, low-flow periods from September 1990 to October 1992. The study was done to assist local and state regulatory agencies in determining total maximum daily loads of nutrients for the basin in order to maintain dissolved oxygen greater than 90 percent of saturation and pH less than 8.5 units. Fifty-one sites, including South Umpqua River, tributaries, and wastewater-treatment plant effluents, were sampled during this period. The study included collection of 537 samples or measurements from surface-water sites, 315 samples of wastewater-treatment-plant effluents, 1,262 field measurements during intensive studies within individual reaches, daily mean flow data from 6 streamflow- gaging stations, daily mean water-quality data from 2 fixed-station monitors recording hourly, and various biological data including bacteria, algae and macroinvertebrates in the river. Also included are notes from field- reconnaissance surveys and a compilation of quality-assurance data.
INTRODUCTION
The South Umpqua River Basin in southwestern Oregon is sparsely populated, with most of the population living along the river corridor. The role of point-source discharges to the river, which has been implicated as contributing to the degradation of water quality and to the process of
eutrophication, is the subject of a water-quality study done by the U.S. Geological Survey (USGS) in cooperation with Douglas County. Each summer, the South Umpqua River experiences excessive growth of periphytic algae, accompanied in places by undesirable odors and aesthetic conditions. Abundant algal growth occurs in the main stem of the river, and in the lower reaches achieves nuisance levels. The large primary productivity and metabolic activities of the periphyton-dominated community result in high pH values, often exceeding the Oregon State standard of 8.5 units, and dissolved-oxygen (DO) concentrations often fall below the Oregon State standard of 90-percent of saturation. Historically, other water-quality problems have included: (1) high ammonia concentrations, and the potential for ammonia toxicity; (2) large populations of fecal-coliform and fecal- streptococci bacteria; and (3) summertime water temperatures as high as 35°C (degrees Celsius) near the mouth of the river. Frequent violations of water-quality standards prompted the State of Oregon to consider the imposition of total maximum daily loads (TMDLs) for the South Umpqua River, in accordance with the TMDL requirements of the Federal Clean Water Act of 1972 (Environmental Protection Agency, 1986; State of Oregon, 1988). These requirements provided the impetus for the USGS to study the relations between nutrients, growth of periphyton, and DO and pH problems in the river. Data in this report were collected for that purpose.
Purpose and Scope
The purpose of this report is to present a compilation of data collected to meet the following objectives: (1) quantification of primary productivity and respiration of
periphytic algae in the South Umpqua River during summer base-flow periods; (2) clarification of the relation between periphytic algal metabolism and the following: nutrient loading, water velocity, water depth, bottom substrate type, and light intensity; (3) determination of critical nutrient loads to control periphyton growth and achieve water- quality standards for pH and dissolved oxygen; and (4) develop reliable technical procedures, methodology, and protocols applicable to conducting studies of periphyton-dominated streams throughout the United States.
This report contains data collected in the South Umpqua River Basin by U.S. Geological Survey from September 1990 to October 1992. Data are from 51 sites in the basin, including 11 tributary sites, 6 wastewater-treatment plants (WWTPs), and miscellaneous sites where water-quality or biological sampling was performed. River-reconnaissance information and quality-assurance (QA) data also are included. Time-of-travel and reaeration data for the South Umpqua River were previously reported by Laenen and Woo (1994). Values for river miles used in this report were taken from a river mile index for the Umpqua River (Columbia Basin Inter-agency Committee, 1966) wherever possible.

Hydrology and Physiographic Setting of the South Umpqua River Basin
The South Umpqua River Basin is located in southwestern Oregon and drains an area of 1,762 square miles (fig. 1). The South Umpqua River flows into the Umpqua River at river mile (RM) 111.7. Most of the South Umpqua River Basin is within Douglas County, with a small percentage of the basin located within Coos, Josephine, and Jackson Counties. Headwaters of the South Umpqua River are in the Umpqua National Forest in mountainous terrain. The river channel opens up as it descends from the forest into agricultural and urban areas. Physiography and hydrology of the basin and river have been previously described by Rinella (1986).
DATA COLLECTION
Data collection involved the following tasks: (1) reconnaissance of stream characteristics, (2) collection of water-quality and stream-discharge data, (3) physical and chemical analyses of water samples, (4) collection and analysis of biological data, and (5) collection and compilation of quality- assurance data for the National Water Quality Laboratory (NWQL). These tasks are explained in detail below. The dates and purposes of sampling efforts are presented in table 1.
Reconnaissance of Stream Characteristics
Data were collected in 1991 and 1992 with regard to the stream's physical morphology, habitat for algae, and suitability of sampling. Variables recorded include velocity, width, depth, general descriptions of bed material, stream type (pool, riffle, or run), potential access for vehicles or people on foot, and field notes about biological organisms. Limited water-quality data were collected during some of the reconnaissance surveys in 1992. Surveys were done primarily by canoe to allow continuous access to the river. These surveys were done during periods of summer base flow to maximize visibility of channel
features and ensure that data collected were appropriate for the purposes of the study. Seven reaches of the river were covered in this way, including over 50 miles of the South Umpqua River and 3 miles of Cow Creek. Reaches from South Umpqua River at Days Creek to the mouth of Cow Creek, South Umpqua River at Cow Creek to Myrtle Creek, South Umpqua River at Myrtle Creek to Mary More Bridge (RM 143.7), and the South Umpqua River at Winston to Happy Valley (RM 130.0) were surveyed in 1991 (Laenen and Woo, 1994) and are presented in table 2. Tables 3-5 summarize notes for the remaining reaches; South Umpqua River at RM 176 to Days Creek; Cow Creek from Riddle to the mouth; South Umpqua River from Cow Creek to Missouri Bottom (at Pruner Bridge); and South Umpqua River at Oaks to the mouth (RM 111.7). These surveys were completed in June and August 1992.
Channel reconnaissance data were collected at transects every 1,000 to 3,000 feet, with notations regarding the location of pools, riffles, runs, or other important features between transects. An attempt was made to select transects that adequately approximated the conditions immediately upstream and downstream. For safety reasons, riffles were rarely measured directly, but their locations were noted along with estimates of width, depth, and velocity. Transect widths were determined with a calibrated optical range finder. Water depths were measured at the thalweg using a weighted tag-line or a wading rod. Velocity was measured just below the water surface at the thalweg using a Price 1 AA current meter.
Water-Quality-Sample Collection
Water-quality-sample collection included three phases: (1) synoptic surveys, (2) fixed stations and wastewater-treatment plant (WWTP) sampling, and (3) diel-inflow and outflow sampling. In addition, time of travel and reaeration studies were completed (Laenen and

Woo, 1994). Due to the evolving nature of the sampling scheme, wastewater-treatment plants were sampled in conjunction with synoptic surveys in 1990-1991, but were sampled twice weekly in the summer of 1992. Water-sample collection sites are listed in table 6, and shown schematically in figure 2. Discharge measurements at non-gaged stations were made during synoptic and diel inflow and outflow sampling trips and are summarized in table 7.
Synoptic Surveys
The purposes of synoptic surveys were to:(1) allow mass balances of water-quality constituents and thus identify sources and sinks,(2) identify problem areas relative to pH and DO, and (3) provide data to help identify the major processes and factors controlling periphyton metabolism in the stream. Synoptic surveys included discharge measurements, water sampling for chemical constituents, and measurement of field parameters. Water-quality constituents and field parameters are listed in table 8. During synoptic surveys, three teams of field personnel collected samples over 3-day periods, starting in the upper reaches of the river basin and working downstream towards the lower reaches. Synoptic sampling sites, including the location of all major tributaries and known major point sources are shown in figure 1. Measurements of field parameters were made in early morning (0500-0900 hours) and late afternoon (1500-1830 hours) to estimate daily maximum and minimum pH and DO concentrations in the South Umpqua River and Cow Creek. These measurement times were determined by examination of the instantaneous record at the fixed-station monitors at South Umpqua River near Roseburg and at Days Creek. In addition, field parameters were measured during sample collection at all sites regardless of time of day. Samples of WWTP effluent during 1991 synoptic surveys were collected by the respective WWTP operators and chilled until they could be processed by USGS personnel, generally less than 6 hours after collection. Data from the South Umpua
River and tributary synoptic surveys are listed in table 9; data from WWTP effluents are listed in table 16.
Discharge was measured at miscellaneous sites according to standard USGS guidelines (Buchanan and Somers, 1984). Depth and width integrated water samples were collected using the Equal Width Increment (EWI) technique described by Edwards and Glysson (1988), except where otherwise noted. Field measurements were made of temperature, specific conductance, pH and DO using calibrated Hydrolab multiparameter water- quality instruments, adapted for low-ionic strength waters. Field measurements were made in at least three locations in a transect and the values averaged.
Fixed-Stations and Wastewater-Treatment-Plant Sampling
Fixed stations included: (1) sites with streamflow-gaging stations; (2) sites with recording, multiparameter monitors; (3) sampling sites visited weekly or biweekly in summer 1992; and (4) WWTP effluents sampled twice weekly in summer 1992. Fixed stations provide estimates of temporal variability to assist in the interpretation of results from synoptic and diel surveys. The fixed stations are shown in figure 3 and the parameters measured are listed in table 8. South Umpqua River near Roseburg (site number 14312260) is also a National Stream Quality Accounting Network (NASQAN) site; hence some additional data were collected and are presented here. Fixed station water-quality data are given in table 9, streamflow records for streamflow-gaging stations are shown in tables 10-15, and WWTP effluent data are listed in table 16.
Continuously recording, four-parameter monitors, that record water temperature, specific conductance, pH, and DO, were located at an upstream site (South Umpqua River at Days Creek, streamflow-gaging station number 14308600) and a downstream site (South

Umpqua River at Roseburg, station number 14312260). A third recording monitor, which measured light intensity, was located on the roof of the Winston-Green WWTP (site number 430812123240101). Daily values (maximum, minimum, and mean) for individual field parameters are given in tables 17-26.
Weekly sampling sites were selected to provide temporal data regarding the loading and variability of water-quality constituents, primarily nutrients, without the influences of major point sources. Water samples were collected and field measurements were made in the same manner as described above for synoptic surveys. Twice weekly, 24-hour, composite WWTP effluent sampling for nutrients in summer 1992 provided information about the short-term variability of nutrient loads from these plants and seasonal trends in their concentrations and mass loadings to the river. Sampling of WWTPs in 1992 was conducted with the help of the respective WWTP operators, using automated samplers, and students from Umpqua Community College in Roseburg.
Diel Inflow and Outflow Sampling
Diel sampling was done to obtain hourly measurements of field parameters over 24-hour periods. Three or four sites in each reach, upstream and downstream of point sources, in three 5-10 mile reaches of the South Umpqua River were selected for diel sampling (fig. 4). Discharge was measured at least once in each reach during the 24-hour sampling period. In 1992, water samples were collected several times during the 24-hour diel studies and analyzed for nutrients. Diel data may be used for: (1) estimation of periphyton productivity, in conjunction with time-of-travel and reaeration estimates (Odum, 1956; Britton and Greeson, 1987), and (2) estimation of variability of water- quality that may be associated with algal activity or variable loadings from WWTPs. Field-measurement data collected during these studies are given in table 27. Analytical results
of water samples collected during diel studies are given in table 9.
Twenty-four-hour measurement of field parameters at secure, normally non- instrumented sites was accomplished by use of calibrated, recording, four-parameter minimonitors in 1991 and calibrated recording Hydrolab multiparameter water-quality instruments in 1992. Probes were temporarily attached to stakes driven into the river bottom near the centroid of flow. In each reach in 1992, a light meter was deployed in the water with one of the water-quality monitors. Light measurements in the water were made using a submersible Li-Cor spherical quantum sensor, controlled by a Campbell CR-21 data-logger, and stored on a Campbell SM192 storage module. Instruments were programmed to record parameter values hourly. Unsecure sites were visited approximately every 3 hours, timed to coincide as much as possible with projected minima and maxima of the daily pH and DO cycles, and field parameters were measured manually with a Hydrolab. Data recorded automatically were downloaded to a laptop computer and subsequently transferred to a USGS database. Data collected manually were entered separately into the database.
Physical and Chemical Analysis of Water
Samples
Water samples were processed immediately in the field and prepared for shipment to the NWQL. Sample preservation requirements are outlined by Fishman and Friedman (1989). Parameters analyzed and the associated NWQL labcodes or schedules are listed in table 8. Subsamples were taken from a churn splitter with unfiltered subsamples drawn first. Subsamples for dissolved constituent analysis were collected and filtered through a pre-rinsed, 120 mm diameter, 0.45-|j,m (micrometer), pore-size membrane filter. Nutrient samples were preserved with mercuric chloride (HgC^) and stored on ice in opaque polypropylene bottles. Preserved samples were shipped overnight on ice to the NWQL where

they were kept refrigersted at 4°C until analysis. Generally, nutrient analyses were performed within 7 days of delivery. Analyses were performed according to the procedures described by Fishman and Friedman (1989).
Effective October 1, 1991, NWQL analysis for high-level total phosphorus (TP-labcode LC1688) and total Kjeldahl nitrogen (TKN-LC084) changed from USGS Techniques of Water Resources Investigations method I-2600/I-4600 (Fishman and Friedman, 1989) to method I-2610/I-4610 (U.S. Geological Survey, written commun., 1992). The purpose for this change was to produce a more effective and thorough digestion of unfiltered samples. This method change affected only the WWTP effluent samples collected in 1992, because river samples were analyzed by a different procedure.
Biological Data Collection and Analysis
Three categories of biological samples were collected: (1) periphytic algal samples for biomass, species identification, and analysis of tissue nutrient content; (2) bacterial samples for enumeration of fecal streptococcal and fecal coliform bacteria; and (3) samples of benthic macroinvertebrates for identification and enumeration.
Algal Sampling
Periphytic algae were sampled using either Surber or Hess samplers, which were placed on the riverbed in representative locations. The areas delineated by the Surber and Hess samplers were 0.093 and 0.086 m 2 (square meter), respectively. The Surber sampler net had a nominal pore size of 210 micrometers. A knife was used to circumscribe the inside perimeter of the sampler and algae were scraped from the rocks and collected in the sampler's net. Samples were rinsed in the net, removed, and dried in the field. Further drying and ashing was done in the USGS Oregon District laboratory. Biomass was determined as dry weight and as ash weight (Britton and Greeson, 1987), expressed as mass per unit area
of the riverbed. Biomass results are shown in table 28.
Algae samples for species identification were scraped or pulled from several rocks at selected sites and composited. Samples were preserved in formalin and identified to species level by Aquatic Analysts, Portland, Oregon. Relative abundances were noted as well. Results are listed in table 29. Composite samples for nutrient content of algal tissue were sun dried in the field, stored in jars, dried in the laboratory at 105°C, and analyzed by Huffman Laboratories in Denver, Colorado. Carbon, hydrogen, and nitrogen were determined using CHN analysis. Phosphorus was determined by acid digestion followed by Inductively Coupled Plasma analysis. Results are expressed in terms of percent of sample dry weight, and are shown in table 30.
Bacterial Sampling
Sampling for fecal streptococcal and fecal-coliform bacteria was accomplished on two occasions in the late summer and fall of 1992 along with synoptic and diel inflow and outflow studies. Grab samples were collected from each site in sterilized bottles, filtered, incubated, and enumerated in the field according to the methods described by Britton and Greeson (1987). Results are given in table 31.
Benthic Macroinvertebrates
Benthic macroinvertebrates were sampled using a Surber sampler. The sediment and algae within the sampler's perimeter were stirred and allowed to float into the net of the sampler. The resulting conglomeration of sediment, algae, and invertebrates was preserved in formalin. Macro-invertebrates were separated from the algae and debris under a dissecting microscope at a later date and enumerated to order level to allow for differentiation by functional group. Samples were checked at random by a second biologist to confirm identifications. Macroinvertebrate identification and enumerations are presented in table 32.

Quality-Assurance (QA) Program
Quality assurance was incorporated into the sampling design using a variety of techniques, including: (1) pre- and post- calibration of multiparameter water-quality probes (Hydrolabs), (2) weekly or biweekly calibration of fixed-station monitors at Roseburg and Days Creek, (3) replicate water- quality samples, (3) field and equipment- sampling blanks, and (4) reference samples sent to the NWQL with nutrient levels in the ranges found in the South Umpqua River and WWTP effluents.
On a daily basis, Hydrolabs were calibrated immediately prior to and after use, according to the manufacturer's recommendations. Calibration results were recorded in maintenance logbooks for each instrument. Slight linear shifts were applied to temperature, specific conductance, pH, and DO when calibration differences exceeded 0.2°C, 5 percent, 0.2 pH units, and 0.2 mg/L (milligrams per liter), respectively. Similarly, data from fixed-station monitors were shifted on the basis of field-calibration results. USGS techniques for the computation of streamflow records (Kennedy, 1983) were applied to water-quality data to shift, develop, and check field-parameter data from these monitors.
Replicate and field-blank samples were collected during synoptic , fixed-station, and WWTP sampling trips. QA data, including replicate and blank results, are stored in in the WATer STOrage and REtrielal System (WATSTORE) and are shown in table 33. Reference samples were prepared at the USGS Oregon District laboratory and sent to the NWQL for analysis. Laboratory-blank samples consisted of inorganic blank water supplied by the USGS laboratory supplies facility in Ocala, Florida. This water was transferred to sample bottles in the district laboratory prior to shipping to NWQL. Blanks were preserved and treated identically to field samples. Analytical results of reference samples and laboratory- blank samples are shown in table 34.
Quality-control samples from the field (replicates and field blanks) were labelled in 5 or 10 minute increments after the original sample time. All QA samples taken at a site where QA sampling was done are listed in table 33. Table 33 also includes the original samples, which appear in table 9. The first QA sample from a site is therefore the original; the second sample is generally a replicate, with a sample time 5 minutes later than the original; and the third sample is usually a field blank (except where triplicate samples were collected), with a sample time 10 minutes later than the original.

Table 16. Water quality of wastewater-treatment plant effluents in the South Umpqua River Basin, Oregon, 1990-92
[Samples were analyzed at U.S Geological Survey's National Water-Quality Laboratory in Denver, Colorado. Some of the samples are 24-hour composite samples and are listed with start and end times for the
sampling period. Discrepancies between total (unfiltered, digested) phosphorus and dissolved phosphorus (filtered, digested) or orthophosphate (filtered, undigested) may reflect the analytical uncertainty of the
procedures used. "K GAL" = thousands of gallons; "US/CM" = microsiemens per centimeter at 25 degrees Celsius, "MGT." = milligrams per liter; "TOTAL" = unfiltered, digested, "dissolved" = filtered,
"CACO3" = calcium carbonate; "N" = nitrogen; "NO2+NO3" = nitrite plus nilrate; "P" = phosphorus; "--" = not analyzed or not available; "E" = estimated, "<" = less than, ">" = greater than, "JUN" = June;
"JUL" = July; "AUG" = August; "SEP" = September; "OCT" = October)

Table 34. Quality-control reference-sample results for nutrient samples analyzed by the National Water Quality Laboratory in 1991 and 1992
[Reference samples of nutrients were submitted to the NWQL (National Water Quality Laboratory) in concentrations varying within the range of values being reported by the NWQL for South Umpqua River Basin water samples, including wastewater-treatment plant (WWTP) effluent samples. The values reported by the NWQL are given in the top section of the table and are denoted as S1-S14. The corresponding expected values for the same reference samples are given in the bottom section of the table. "QA" = Quality Assurance; "mg/L" = milligrams per liter; "N" = nitrogen; "P" = phosphorus; "S1"-"S14"= reference samples 1 through 14; "LB" = laboratory blank; "--" = missing data or not analyzed; "<" = less than]
