Hydrocarbons
in the Kenai River
During the summer of 2004, KWF completed the most intensive hydrocarbon
monitoring of the Kenai River to date. Our goal was to look at the
estuary portion of the river and better document how much fuel is
in this stretch of the river and what affect the tide has on the
levels we have been reporting over the past five years. Over a very
busy weekend, we collected one sample every three hours from the
middle of the river near the Kenai City Dock, Warren Ames Bridge
and Cunningham Park. The 48 samples we collected should give us
a better understanding of how fuel from the in river fishing moves
downstream and how much the lower river dipnet fishing contributes
to the pollution load. Since we conducted this on a Saturday and
Sunday, it will also give us the first insights into any differences
we see on days with guided fishing boats compared to non-guided
boats. This is a never ending controversial topic, and one that
KWF can now put some real numbers on. There are no real surprises,
by anyone’s measure, there is a great deal of gas that goes
into the river and gets flushed out to Cook Inlet.

Baseline
Water Quality Monitoring
In April 2005, KWF completed its 5th year of baseline sampling
of the Kenai River Watershed. Every April and again in each July
since 2000, water samples have been collected at 21 sites from Cooper
Landing to Cook Inlet.
Our plan has been successfully carried out by having numerous
agencies dividing up the workload to cover a big watershed. Six
sampling teams each collects a sample from 2 to 4 sites, depending
how hard they are to access. This strategy covers all 21 index sites
in a single day. Each water sample is then evaluated at a 30% discount
by Analytica Laboratory in Anchorage. Our coordination and multiple
agency participation have combined to create a data set to use as
a starting point for assessing the health of the Kenai River by
looking at the concentrations of metals, nutrients, hydrocarbons,
and bacteria. We will continue this monitoring effort as long as
funding is available to do this important work.
We’d like to thank our many partners in this project: Brad
Olson, and his team from Analytica Group Testing Lab, City of Soldotna,
Kenai River Sportfishing Association, Inc., Kenaitze Indian Tribe,
U.S. Forest Service, Kenai National Wildlife Refuge, Kenai Peninsula
Borough, Cook Inlet Aquaculture Association, Alaska Departments
of Natural Resources and Environmental Conservation. Many others
behind the scenes are invaluable. No agency or non-profit has the
ability to do this alone so we Thank You!
Flow
Monitoring
The Greek philosopher ~Heraclitus (c.535 - 475 BC) said "You
cannot step into the same river twice". This eloquently states
why we monitor the amount of water flowing in key streams, at any
give spot on any given stream, the water is constantly changing
as it flows toward the ocean. Water quality is different when on
the rise during a flood compared to when it is receding and very
different between peak runoff times and dry periods. We cannot say
very much about water quality without understanding water flow.
Different streams exhibit vastly different flow patterns on the
Kenai Peninsula, largely dependent on the presence or absence of
glacial melt. How fish respond to changing flow is poorly understood,
and we seek to more clearly understand this. In addition to how
much it rains or how much and how fast the snow or ice melts, some
of the factors controlling stream flow include characteristics of
the watershed such as : percentage and type of wetlands, how much
pavement ( or other hard surfaces that shed 100% of rainwater),
forest type, and topography. Water runoff behavior in Alaska is
significantly less understood than in the other States; however,
many decisions important to fish and other aquatic life are based
on the best available information - it is our goal to make an important
contribution to better understanding the water flow characteristics
of smaller streams that are the nurseries of juvenile salmon.
Continuous
Water Quality Monitoring of the Kenai River
If you went dipnetting this summer, you probably noticed our new
yellow buoy. We have upgraded one of our instruments that monitors
water temperature, dissolved oxygen, conductivity, turbidity and
pH every 15 minutes round the clock. The data is then transmitted
to a satellite via phone modem, then sent to our office via Email.
We are now working to get this data published on the internet in
near realtime. |
