Eel River Water Quality Monitoring Project (2002) 3 Humboldt County Resource Conservation District for the California Department of Fish and Game Agreement #P0110546

Overview

The Humboldt County Resource Conservation District (HCRCD) has now completed eight field seasons (1996-2003) of temperature monitoring in the Eel River watershed. This report is the summation of the last two years of this multi-year project

Stream temperature has been a concern in watersheds throughout the Pacific Northwest in relation to salmon and steelhead populations. The effects of past land use activities and potential future impacts to these watersheds have led to a number of regulatory actions that are intended to mitigate the adverse affects of increased temperatures. Restoration activities and resource extraction need to be designed after scientifically based assessment and monitoring is in place.

With the advent of relatively inexpensive continuous temperature recorders, such as the “Onset” HoboTemp series, temperature monitoring has been shown to be one of the most cost effective tools available to land use managers for accessing present conditions and health of existing fisheries and other constituents of the aquatic habitat. Monitoring protocols developed over the past few years by researchers in government and the resource industry have been refined and completed by the Institute for Forest and Watershed Management (IFWM) at Humboldt State University. They provide a sound scientific basis for gauge deployment and data management. (See appendix 2)

In general, the study involved the placement and retrieval of temperature data loggers in upwards to two hundred locations throughout the Eel River’s 3,684 square mile watershed. After logger retrieval, the data was downloaded, archived in summary form, and made available to all “stake holders”.

Many cooperators have assisted the HCRCD these past two years in accomplishing this very large project and our thanks to them, especially the California Department of Fish and Game, cannot be overstated. The real success of this project is being realized as researchers, watershed stewards, and landowners alike use this large data set to probe the health of the Eel River. Information gathered from the first two years of this study is presently being used by many of the Eel Rivers “share holders” including California Department of Fish and Game, researchers at the University of California (Berkeley), Redwood State Park, Trout Unlimited, Eel River Salmon Restoration, and several private landowners.

Protocols and Quality Control

In an effort to standardize fieldwork and logger accuracy with regard to stream temperature monitoring, the HCRCD has adopted the protocols as set forth by the IFWM at Humboldt State University. These protocols were designed with assistance from the Fish, Farms, and Forest Communities Technical Committee and adaptations from similar protocols in Washington and Oregon.

Quality control tests were run on all HCRCD temperature data loggers prior to the field season. Results of these tests are available for review but are so voluminous they are not included here. The tests were conducted in the following manner. June 17, 2002 and May 23, 2003 the data loggers were “launched”, placed in a cooler and left for three hours. Gauges were then down loaded and checked for relative accuracy. This test proved to be very accurate with regard to the NIST traceable thermometer as temperatures “flat lined” for at least an hour. This type of procedure, without ice, tests the gauges in a relatively close thermal unit as encountered with the field Eel River Water Quality Monitoring Project (2002) 4 Humboldt County Resource Conservation District for the California Department of Fish and Game Agreement #P0110546 deployment. All gauges responded positively to this test and random sampling of gauge accuracy was found to be within the manufacturer’s specifications (+/-1 degree C).

Cooperators

Cooperators in the Eel River Temperature Monitoring Program for 2002 and the 2003 field seasons included: Pacific Lumber Company- SCOPAC, Scotia, CA. Robert Darby Barnum Timber, Arcata, CA. Robert Barnum University of California, Berkley Nature Center (Elder Creek). Camille McNeely, Peter Steele Mendocino Water Agency, Ukiah, CA. Dennis Slota California State Parks, North Coast Redwoods, Dyerville Section, Weott, CA. Rocco Fiori California Department of Fish and Game, Fortuna, CA. Trevor Tollefson California Department of Fish and Game, Willits, CA. Scott Harris Eel River Salmonid Restoration Project, Bill Eastwood and Harry Vaughn U.S. Forest Service, Eureka Field Office, Adam Dresser, Andrew Bundshu U.S. Forest Service, Covelo Ranger District, Covelo, CA. Round Valley Tribe, Covelo, CA. Skip Thompson, Warren Mitchell Kyle Keegan and Jack Monskie Assorted private landowners: Tom Long Road Association

Many of the above cooperators have obtained their own gauges for internal studies and share their data with the HCRCD for this compilation. In addition to their own gauges the HCRCD loans out additional loggers to help cooperators extend their studies. The combined total of loggers successfully retrieved, downloaded and archived by these cooperators provides the HCRCD much better sampling coverage.

Results of the 2002 and 2003 field seasons are presented with little discussion as this project was designed to coordinate the deployment of temperature data loggers and compile results. Attempts to interpret findings are beyond the scope of this project. Therefore, there will be no analysis provided here outside noting trends when evident. Each of the major sub-basins (Mainstem, South Fork, North Fork, Middle Fork, and Van Duzen) are treated independently and data are grouped to define the general progressive heating of the water bodies as they flow downstream until reaching the cooling effects of coastal influences.

The raw and validated data from this survey will be archived in several locations for future use by interested parties. These locations include:

Eel River Water Quality Monitoring Project (2002) 5 Humboldt County Resource Conservation District for the California Department of Fish and Game Agreement #P0110546 Estimated Cost Share and In-Kind Contributions

In the course of the two years a total of three hundred and seventy-five data loggers (231 HCRCD plus 144 belonging to cooperators) were deployed. This activity represents a good deal of time and effort from individuals from: private landowners, watershed coordinators, California State Fish and Game, U.S Forests Service, and Mendocino County Water Agency. This work was valued at $8,640 using a formula based on average field deployment/retrieval time of four hours and at a conservative wage of $15/hour. (Note: This figure does not include time from State employees.)

Data management*, analysis and report writing for all cooperator’s gauges placed in the Eel for the two seasons accounts for additional match. This work, valued at $4,680 includes work accomplished by trained data managers proficient in spreadsheet and database programs. Again a conservative estimate based on conversations with cooperators of 260 hours and an average salary of $18/hr.

A total of $13,320 is available for matching HCRCD activities in this project. * Includes costs for cooperators exporting files, cleaning, and storage with accurate placement of deployment location indicated on Digital Raster Graphed Quads

Stream Temperature Monitoring Site Report

Each site has a three-page report with site information and summaries of various temperature metrics. Reports can be obtained from the MS Access database. To print these reports from the Eel River Water Quality Monitoring Project (2002) 7 Humboldt County Resource Conservation District for the California Department of Fish and Game Agreement #P0110546 database, select the Reports tab and choose YEARLY_SITE_REPORT.rpt from the list. When this document is opened, the user will be prompted for the year of data. These graphs include the following:

1) Plot of daily average temperature. 2) Plot of seven-day moving average vs. a temperature reference value of 18.3ΕC. 3) Graph showing frequency of observations per temperature class and percent probability of exceedance for a given temperature. (See pg. 27)

(Sample printout from “Stream Temperature Monitoring Site Report is to be found in Appendix 1.)

2002 and 2003 Field Seasons:

In 2002 the HCRCD and their cooperators deployed one hundred and ninety-five (195) temperature data loggers in mainstem and tributary reaches of the five sub-basins. A total of one hundred and eighty-three (183) gauges were recovered from the field and one hundred sixty (160) are reported here. Ten gauges were lost or stolen. Others sustained gauge/gauge case/battery failures and data was corrupted or lost.

In 2003 the HCRCD and their cooperators deployed one hundred and eighty (180) temperature data loggers in mainstem and tributary reaches of the five sub-basins. A total of one hundred and seventy-two (172) gauges were recovered from the field and one hundred fifty-seven (157) are reported here. As in 2002, a number a data loggers were either lost, stolen or the data was deemed corrupted for one reason or another.

Mainstem Eel River

Fifty-two gauges are reported for 2002 and fifty-four downloads are reported for 2003. Upper Mainstem Eel River temperatures show a general warming through this two-year period. This is evident in most of the upper tributaries (i.e. Broaddus and Panther Creeks). 2002 was a bit cooler in many areas closer to the coast. (Compare Ryan, Tomki, and Willits Creeks to 2000 and 2003 MWATs.) This is evident even in the Lower Eel River tributaries within the coastal fog belt. (Howe Creek and Thompson Creeks.)

South Fork Eel River

Forty-seven (47) data loggers are reported for 2002 and forty-five successful downloads from 2003 in the South Fork these past two seasons. This basin generally is the most studied due to its relative ease of access. But water draws by the many landowners that inhabit this drainage are cause for concern. This is especially true for the cold-water inputs that flow from the populated sub- watersheds on the east facing slopes. Streams in the Salmon, Sproul, Redwood, and Bull Creek drainages bear special attention due to the rising amount of urbanization and unregulated summer take.

Temperatures in this more coastal basin were on average just slightly warmer than the 1999 through 2001 recordings at the same locations. This is very likely due in part to warmer general weather patterns for the two years. A comparison of ground water flow and regional air temperatures for the duration of this data would be helpful in identifying trends when fluctuations are this small. Headwater streams in relatively natural settings such as Elder Creek, Dutch Charlie and Jack of Hearts Creek, all near the town of Branscomb; show slight cooling in 2001-2002 but then a slight increase in 2003.

Middle Fork Eel

Figure 4 Middle Fork Eel River:

Sixteen (16) gauges and seventeen (17) are reported for 2002-2003 field seasons respectfully. An important system with regard to refugia associated with summer steelhead populations, the Middle Fork is significant in that most of the land holdings in the drainage are in Tribal and Federal ownership. This makes dealing with the problems facing this watershed somewhat easier to deal with even though these are the most inland sites for the Eel River system.

Temperatures in the Middle Fork Eel River demonstrated a slight rise over the past two years of this study. Beaver, Rattlesnake, and Middle Fork at Osborne pool are examples of one degree Celsius rise.

North Fork Eel River:

Fifteen gauges were recovered this field season in the North Fork Eel River and successfully downloaded in 2002. In 2003, twelve downloads were kept for the study. The Mad River Ranger District, U.S. Forest Service is of great assistance in this remote drainage. The lack of gauges in this region is two fold. Partly due to this remote character and partly due to a drop in staffing at the Mendocino National Forest, USFS as they had placed a number of North Fork loggers in the past. The Natural Resource Department of the Round Valley Tribe had placed three to five gauges in past years but has opted out of our cooperative effort for the time being. As a result, very little should be inferred from this small sample. The data may still prove quite valuable as we continue this project in the coming years.

Van Duzen River:

A total of twenty-five data loggers were deployed and retrieved in the Van Duzen River these past field seasons. This includes eighteen gauges that were placed in this drainage by Pacific Lumber Company.

One gauge was placed above Eaton Roughs, near the town of Dinsmore in 2003. Although this is considered above anadromy, it was deemed prudent to see what mainstem Van Duzen temperature was prior to reaching the area that does contain salmonids. This basin again demonstrated a cooling trend throughout. Grizzly Creek is a good representative showing decreases from 22.4 C to 17.4 C into 2002 and the a one degree rise in 2003. A cursory review of the 2002-2003 data sets display a very slight warming these two years when one compares the MWAT average. (See Table 7) .

SUMMARY OF THE TWO-YEAR PROJECT

General Project Activity

A) Cooperators:

Undoubtedly the most successful aspect of this project over the course of the past few years is the impressive assistance the HCRCD has received from our many cooperators. In total, the HCRCD has been fortunate to have worked with sixteen different agencies, groups and individuals. In all, its been a very positive and rewarding relationship. That said, the vagaries of working with volunteer individuals and/or groups do not come without its problems. Federal and State agencies have changed personnel mid field season. This has added unnecessary confusion to the communication linkage and has led to lost gauges and data. In the private sector, timber companies often have an issue with public disclosure of their data. It is very unfortunate that the HCRCD lost Campbell Timber Company as a contributor when one of the state bureaus held them accountable for legacy activities on properties they had recently purchased from Georgia Pacific Corporation. This was done using the companies freely given temperature data. Until that time, Campbell’s Natural Resources Department had provided the HCRCD with 18-25 sites from their South Fork Eel River holdings. The HCRCD has endeavored to keep all of their partners involved with this cooperative effort to maximize the coverage and provide all user groups with the most complete and accurate temperature profile of this large basin. Thanks to these cooperators the HCRCD can be boastful when regarding the total matching discussed below. Their efforts greatly expand the grant funds obtained that nurture this endeavor.

Eel River Water Quality Monitoring Project (2002) 24 Humboldt County Resource Conservation District for the California Department of Fish and Game Agreement #P0110546 B) Hardware, Software and Deployment Issues:

Prior to the upcoming field season all data loggers under the control of the HCRCD are tested for operational accuracy (see Protocols and Quality Assurance p. 5 this document).

Every two years batteries are replaced in the HoboTemp data loggers. (StowAways have a ~ten year permanent battery installed at the factory and can not be replaced by field personnel.) This helps ensure less problems with deployments but poorly sealed units or cases disturbed by the unaware public have caused damage and sometimes loss of HCRCD gauges. Data loggers are plugged into the computer via a patch cord and linked to the BoxCar software for deployment (launching) and retrieval (download). A highlight of this program has been the outstanding relationship between the HCRCD and Onset Computer Corporation has maintained. Onset manufactures the continuous recording data-loggers used throughout the project. Their very knowledgeable staff has been a continual resource when trouble-shooting issues regarding their HobTemps and/or the BoxCar software. The software has proved reliable and extremely easy to operate and maneuver to spreadsheet programs such as EXCEL or Lotus. The HCRCD purchased a hundred and seventy five (175) of the HoboTemp data loggers in late summer of 1995. These gauges have served us well and, despite the expected attrition, the HCRCD has one hundred and twelve of these after eight field seasons.

Some deployment problems have arisen mainly out of improper training prior to sending field personnel out to sites. In a few instances loggers, which have to “launched” via a computer have not been set up correctly. In these cases the logger is deployed and then retrieved three months later only to find out that the gauge was set to record for three hours. One interesting side note was one gauge that was deployed up a small tributary on the South Fork Eel (McCoy Creek). The gauge was lashed down a bit too severely with wire to the point where heating and contracting broke the wire and the gauge floated free. Two years later, the gauge was found on a beach in Oregon near the town of Yachats. Most of the loggers are deployed in airtight containers in which are placed a short statement regarding the project and where to send if found. This was the winner for returns.

C) Sites and Site Selection:

Original site location for this project was decided on at planning meetings held with California Department Fish and Game Biologists, U.S. Forest Service personnel familiar with sub-basins, California State Park Ranger, several fisheries biologists from the timber products industry, and members from the State Water Quality Board staff. Sites were chosen for fisheries value, owner access, public access, and representational qualities of the watershed. In all, a total of four hundred and eighty-five (485) sites have been identified as placement locations in the Eel River system. Many of these sites were changed by design due to low water issues or loss of access. Field personnel not returning to the correct site changed some locations. A movement of over fifty feet was deemed a new site by IFWM to keep variables at a minimum. A review of the site map provided by IFWM in the analysis section will help clarify placement locations and give a quick view of MWAT for that location for that year.

Eel River Water Quality Monitoring Project (2002) 25 Humboldt County Resource Conservation District for the California Department of Fish and Game Agreement #P0110546 D) Uses of the Data to Date:

Another of the successes of the monitoring project is the number or resource agencies and shareholders that have made use of all or part of this data set. The HCRCD, the Eel River Watershed Improvement Group, and the Eel River Salmon Restoration Project have used this temperature information to validate and monitor work planned, underway, or completed as they deal with landowners in various drainages to improve habitat for trout and salmon. University of California biologists from Berkeley have used the data for macro-invertebrate studies in the Elder Creek and Bull Creek drainages of the South Fork Eel. They are studying the food webs that support the growth of juvenile steelhead at the Angelo Coast Range Reserve. The Federal Energy Regulatory Committee, CDF&G and Trout Unlimited have made use of the data as they review temperature changes in the mainstem Eel River with regard to water allocations to the PG&E Potter Valley Hydro-electric facility. State Water Resources Control Board and the North Coast Regional Water Quality Control Board have also used this data for monitoring stream temperatures with regard to the 303d listing. Future use is unknown but expected to continue at higher levels as the data sets become more available through activities such as KRIS Coho for the Eel River, which is underway at this time.

E) Operations and Procedures:

What follows is a brief description of yearly activities that take place to get the loggers in the field and then into a format usable to the user groups. As mentioned above, loggers are pre-tested then provided to field personnel for the deployment. Once the field technician reaches the location for the deployment, generally after driving goodly distance, he or she would then further locate the same site at which the logger had been placed in previous years. Since the river is a living entity pools, riffles, and runs change over the course of time so small deviations are acceptable. Most field workers tie the gauge to a rock or tie it to a submerged root wad where possible. A field form is completed (see Appendix 3) and photo (s) are taken to backup drawings of the location. In high use areas caution is taken to hide the gauge as much as possible. The HCRCD gauge cases were spray-painted camouflage to conceal their location to prevent tampering. At the conclusion of the field exposure the data logger is retrieved and downloaded to a file for that years DTFs (data transfer file).

After receiving the downloads from cooperators, the HCRCD sub-contractor then complies field data forms, reviews placement information foe accuracy, constructs an EXCEL spreadsheet to manage the years downloads from the various cooperator and then turns over all down loads and field forms to the Institute for Forest and Watershed Management. (Refer to Appendix 2).

Product Deliverables to Data Contributors

Data Verification and Validation:

Consistent gauge placement verification, data validation, and calculation of various stream temperature metrics are performed by the Institute for Forest and Watershed Management (IFWM) for each data contributor.

Spatial accuracy is critical to placing stream temperature gauges in the proper landscape perspective. The IFWM geo-references all stream temperature monitoring sites through iterative conversations and correspondences with data contributors.

All stream temperature data are then plotted and anomalous readings are flagged. These flagged values are sent to each data contributor for verification that the readings are due to ambient air exposure or some other anomaly. If the data contributor cannot verify that the anomalous reading(s) is not a true water temperature reading it is left in the data set.

Calibrations are requested from each data contributor. These data are stored in a relational data that links back to the temperature sensor serial number.

Chronic and Acute Exposure Calculations:

Cadres of stream temperature metrics are calculated that are considered to be indicative of both chronic and acute thermal stress at the growth and development stages for salmon and steelhead.

Daily minimum, maximum, and means are then calculated for each site using Statistical Analysis System Software (SAS). Seven-day moving averages are calculated for both the daily means and the daily maximum for each site/year using SAS. Daily and weekly statistics are included in the final data package that is submitted to the data contributor.

Chronic Exposure Calculations and Variables

Time series plots of the seven-day running averages are generated. The seven-day moving average of the daily average and the seven-day moving average of the daily maximum are plotted and compared to a threshold of 18.3°C. These graphs are included in the final data package.

The following are descriptions of each of the variables included in the chronic exposure data set:

Site_ID assigned to each temperature monitoring station. Site-specific information for each site can be found by referring to the join file.

Date The date the daily stream temperature data were collected. The format is day- month-year. Example: 01AUG96

Freq The number of readings for that date. For example, if Freq = 15, 15 readings were used for that day to calculate the Dailymin, Dailymax, Dailyavg, Mov_avg, and Max_avg.

Dailymin The lowest temperature for a 24-hour period, in °C.

Dailymax The highest temperature for a 24-hour period, in °C.

Dailyavg The daily average for all readings in a 24-hour period, in °C.

Mov_avg The seven-day moving average of the daily average, in °C.

Max_avg The seven-day moving average of the daily maximum, in °C.

Dayoweek The day of the week, with Sunday being Dayoweek = 1, Monday being Dayoweek = 2, etc.

Year The year in which the data where collected. Although the year is part of the Date variable, a separate Year variable makes sorting of the data by year easier. A four-digit format is used. Example: 1996.

Several acute thermal stress variables have been calculated from the data. These variables give a clearer picture of the frequency and duration of stream temperatures above an acute threshold. A different acute threshold can be used for each species and each life stage.

Acute Exposure Variables

Variable Description

HRS_HI total number of hours above the acute threshold for the site/year

HR_CN_HI longest stretch of consecutive hours above the acute threshold for the site/year

HR_CN_DT date and time of the last hour of HR_CN_HI

DY_HI_n number of days with = 'n' hours above acute threshold, m = 2, 3,...

DY_HI_Cm no. days with = 'm' consecutive hours above threshold, n = 2, 3,...

SUM_DEG sum of degrees above acute threshold, similarto degree day

We provide the results from four iterations of the above acute variables using four different temperatures, 23°C, 24°C, 25°C, and 26°C.
