INTRODUCTION
The purpose of this report is to comply with Article 33 of the
Federal Energy Regulatory Commission (FERC) License which states
that a water quality moni taring program must be developed to
evaluate water temperatures in the lower Bradley River particularly
as they may be related to the production of fish resources.
The monitoring program was developed and presented in the Bradley
Lake mitigation plan published in November 1985 (Alaska Energy
Authority, 1985). This is the eighth annual progress report and
covers water quality data collected during the period -December
1992 through November 1993.
Information presented includes intragravel and surface water
temperatures in the Bradley River and surface water temperatures
in the North Fork of the Bradley River. Also included are surface
water temperature and turbidity measurements collected at the
Bradley River fish camp by the fisheries study crew during the July
to September period.
The Bradley Lake Hydroelectric facility began operation in the fall
of 1991 and was operational during the period of this study.
Discharge volumes in the Bradley River during the 1993 water
quality monitoring period were characteristic of operational flows.
This annual report is the third to report on water quality during
the operational flow regime.
METHODS
surface and intragravel water temperatures continued to be
collected at two-hour intervals utilizing Model DP212 omnidata
Datapod digital recorders as described in the 1988 Annual Water
Quality Report (Alaska Power Authority, 1988). Figure 1 depicts
the locations of the temperature stations.
The datapods were serviced at approximately monthly intervals.
Some variation in servicing interval occurred because of weather
limitations. The longest period between servicing was
approximately 5 weeks. At each servicing, the datapod surface
temperature reading was compared with a reading obtained from a
hand held thermometer in open water near the surface probe.
Additional surface water temperature and turbidity data were
collected during the mid-July to mid-September period by field
personnel associated with the Salmon Escapement Monitoring Study.
This information was collected at the fish camp which is about 150
ft. downstream from the Tree Bar Reach datapod station.
Temperature readings were always collected at 8:00 am. Turbidity
was usually measured in mid-afternoon.

RESULTS
The intragravel and surface water temperature data for December
1992 through November 1993 are presented in graphic form by month
and by study site. An annual graph has also been produced for each
study site. The monthly graphs were prepared using a computer
program which plots each of the 2 hour temperature readings
obtained from the datapods. Temperature readings that were
obviously erroneous due to datapod malfunction were filtered out
of the data prior to plotting. The annual graphs were prepared by
computing the average daily temperature from the 12 daily
temperature readings and plotting the average daily temperature for
each day of the December to November period. Complete printouts
of the data are not presented here due to their bulk, but are
available upon request from the Alaska Energy Authority.
Riffle Reach
The record for Riffle Reach contains several gaps. Portions of the
months of May, August, and September have incomplete records due
to unknown datapod malfunction and/or prematurely expired
batteries. The maximum variation between the datapod reading (when
operating correctly) and the hand held test thermometer was 0.5
degrees c. with variation usually less than 0.3 degrees.
Graphs of the surface and intragravel water temperatures for the
months December, 1992 through November, 1993 are presented in
Figures 2 through 13 and the annual temperature record is presented
in Figure 14. The general trends observed were similar to those
seen in past years except that maximum temperatures during the
summer were substantially higher than have been observed
previously. The higher temperatures were a result of unusually
clear, mild weather that occurred in June and July.
Tree Bar Reach
The temperature record for Tree Bar Reach is complete except for
datapod malfunctions which occurred in May, August, and September.
The maximum variation between the datapod reading (when operating
correctly) and the hand held test thermometer was 0.5 degrees c.
with most variation less than 0.2 degrees.
Graphs of the surface and intragravel water temperature for the
months December through November are presented in Figures 15
through 26 and the annual temperature record for the full period
December through November is presented in Figure 27. As was the
case with Riffle Reach, temperatures observed during July and the
first half of August were unusually high.
North Fork of the Bradley River
The temperature record for the North Fork contains several gaps
2
including most of April, all of May, most of August, and most of
September. The maximum variation between the datapod reading (when
operating correctly) and the hand held test thermometer was 0. 3
degrees c. with most variation less than 0.2 degrees.
Graphs of the surface water temperature for the months December
through November (excluding May) are presented in Figures 28
through 38 and the annual record is presented in Figure 39.
Miscellaneous Data
Surface water temperature and turbidity data collected during the
1993 Salmon Escapement Monitoring Program at the fish camp near
Tree Bar Reach are presented in Table 1.
RECOMMENDATIONS FOR FUTURE MONITORING
Water temperatures will continue to be monitored from Riffle Reach,
Tree Bar Reach and the North Fork of the Bradley River through
1995. Datapod servicing frequency will continue to be once per
month. A protocol was developed in early 1993 to standardize and
improve servicing procedures and coordination between the several
participants involved in the data retrieval and analysis. Some
improvement in percentage of data retrieval was seen in 1993
compared to 1992. However, data gaps still occurred. At least
some of the lost information in 1993 was a result of bad batteries.
The extremes of temperature and humidity encountered at the Bradley
River stations continued to cause unpredictable malfunction of the
datapods. In the future, all batteries will be checked prior to
use and procedures will continue to be refined. It is recommended
that the instrument boxes currently used at the field stations be
replaced with improved weatherproof fiberglass enclosures.
It is currently planned to prepare a final summary report in 1995
which summarizes pre-operational and post-operational water quality
data and addresses both water quality and fisheries concerns as
they may be related to the operation of the Bradley Lake
Hydroelectric Project.
