4. Water Supply Update
Mr. Goodrich reported:
• Average water use for the month May was 6.75 million gallons per day (mgd).
This usage is 1.55 mgd higher than our 10-year data, and significantly higher
than last year (May 2017) by 1.75 mgd. Usage in June has increased to 8 mgd,
with drier temperatures reported for the month of May.
• For the month of May, there is no change in aquifer storage recovery (ASR)
well conditions. Stored water for ASR well no. 1 is approximately 39 days of
supply based on 1,000 gallons per minute (gpm) recovery rates. ASR no. 2 has
81 days of supply based on 1,500 gpm recovery rates. ASR well no. 1 was last
operated from April 3 to April 11 for testing purposes.
• The June 12 Bonita Pump Station data indicates a pH of 7.68 with 1 mg/L
chlorine residual, 25 mg/L alkalinity, and water temperature of 14.9 centigrade
(57 degrees F).
• Staff received one water quality complaint in the month of May. That
complaint involved strong chlorine taste or odor.
• Water treatment plant operations continued to be normal during the month of
May. Ozone is fully functional and operating without any problems reported by
Lake Oswego Tigard Water Treatment Plant staff. The plant is preparing for
summer operations. Lake Oswego was successful in filling several positions
over the last few weeks due to staff turnover.
• Clackamas River USGS information reports that the river is flowing at 1,550
cubic feet per second (cfs) with a mean value of 2,540 cfs. These flows are
above our conditional use parameters for May June, but significantly lower by
30 percent than the normal average for this time of year. Water temperature is
57 degrees F, with a pH of 7.5 and turbidity at 0.7 NTU.
5. Briefing on Hazardous Algae Blooms (HABs) Water Quality Monitoring on
the Clackamas River
Mr. Goodrich spoke about the recent drinking water advisory issued by the City of
Salem. The advisory was due to cyanotoxins—produced by blue-green algae—
that were detected at low levels in the city's water. The following are some
highlights of Mr. Goodrich's explanation:

SERVING TIGARD, KING CITY, DURHAM,AND TIGARD WATER DISTRICT
■ The media has released information stating that many utilities do not monitor
for cyanobacteria or cyanotoxins because there is no current regulation for
these contaminants. The City of Tigard participates in an active and well-
established source water protection and monitoring plan for sampling and
response to cyanotoxins. No cyanotoxins have been detected in the Lake
Oswego and Tigard Water Service Area's drinking water.
• The Lake Oswego Tigard Water Partnership participates in a voluntary blue-
green algae monitoring program to monitor both the source water and the
treated drinking water. With recent upgrades, the Lake Oswego Tigard Water
Treatment Plant has robust treatment technologies that provide multiple
barriers to remove algal toxins, including: ozone treatment, biological filtration,
and chlorine disinfection, ranked among the best technologies for reducing
algal toxins. At this time, no major algae blooms are reported in our water
source—the Clackamas River.
• Our staff currently collect samples for cyanotoxins twice a month and will
increase this sampling if indication of toxin producing cyanobacteria are
detected in reservoirs upstream of our water intake. In the event of problems
occurring that could affect drinking water, including any imminent advisories
related to HABs or cyanotoxins, council and IWB members will be notified
immediately.
6. Summer Supply Update—Briefing on National Weather Service
Information for the Clackamas River 2018
Mr. Goodrich discussed the effect of unusually dry weather conditions over the
past few months on the Clackamas River flow. Currently the Clackamas River is
running at approximately 70 percent of its average. There have been discussions
and plans in place to ensure sufficient water for the Tigard water service area.
The National Weather Service has released information, which includes a drought
monitor map. Staff will send the board members a web link to this information.
7. Informational Items
