Title: Steven Sobieszczyk,USGS Hydrologist

00:00:16.700 --> 00:00:18.700
So right now we’re over at Burnt Bridge
Creek.

00:00:18.700 --> 00:00:23.580
It’s in Vancouver Washington, so right across
the Columbia from Portland Oregon.

00:00:23.580 --> 00:00:30.880
It’s one of the 44 sites I believe in the
Willamette Valley or the Portland Metropolitan

00:00:30.880 --> 00:00:36.230
area that is part of the Oregon study and
depending on what site we are looking at there

00:00:36.230 --> 00:00:39.440
are a variety of different things we are trying
to determine.

00:00:39.440 --> 00:00:44.040
So here we actually have two monitors in the
stream running 24 hours a day, seven days

00:00:44.040 --> 00:00:49.560
a week that are recording values every 15
minutes or so and it covers your basic water

00:00:49.560 --> 00:00:54.730
quality parameters but then there is also
some newer technologies put on this instrument

00:00:54.730 --> 00:00:57.090
that include chlorophyll and blue/green algae.

00:00:57.090 --> 00:01:02.210
There is also something called an FDOM, it’s
a fluorescence dissolved organic matter, so

00:01:02.210 --> 00:01:07.299
we’re interested in knowing how much broken
down leaflet or how much organics are actually

00:01:07.299 --> 00:01:08.680
making it into the stream.

00:01:08.680 --> 00:01:12.360
The program we’re out here for as part of
the U.S. Geological Survey is the National

00:01:12.360 --> 00:01:17.670
Water Quality Assessment Program, so we have
an acronym for it we call it NAWQA.

00:01:17.670 --> 00:01:22.250
It started in the early 90’s and then every
decade or every ten years or so we’ll do

00:01:22.250 --> 00:01:27.080
another cycle of these assessments, so what
we’re doing is we’re able to actually

00:01:27.080 --> 00:01:32.409
compare and learn about how rivers are responding
to things like urbanization and how people

00:01:32.409 --> 00:01:36.130
are … land is being developed, more people
moving in, more people being born, the effect

00:01:36.130 --> 00:01:41.729
that has on the water and water quality and
we want to see how that changes over time.

00:01:41.729 --> 00:01:47.730
So this data's gonna be available and people
can use that for scouting places to go fishing

00:01:47.730 --> 00:01:54.100
and things like that, so government groups,
regulatory agency groups use it, recreationists

00:01:54.100 --> 00:01:55.100
can use it and then the USGS uses it for its
own kind of historical record and comparison

00:01:55.100 --> 00:01:56.600
and analysis that we like to do.
