GGWC and B2BC volunteers did the third and final stream monitoring
session
of 2011.
Here,
they set up to do the stream profile at the downstream site.
28 August 2011
Volunteers climb over obstacles at the downstream Bridger Creek
monitoring site.
The heavy Spring run-off has undercut the banks,
toppling many trees and bushes into the stream.
Water flow at both sites was much reduced compared to the July session,
so we were able to do profiles and collect macro-invertebrates at both
the upstream and downstream sites.
16 July 2011
Volunteers do a stream profile at the upstream Bridger Creek monitoring
site.
The heavy Spring run-off has dramatically changed the profile –
note the erosion several feet above the water level.
Some of the permanent markers used for monitoring were destroyed and
will
have to be replaced.
Water flow at the downstream site was too deep and swift to do a
profile,
and other monitoring activities at both sites had to be deferred to the
August session.
25 June 2011
Volunteers attended a training course to prepare for the water quality
monitoring sessions that will take place in July,
August and September
of 2011.

Wolman Pebble Count.
Because of the high run-off,
we had to conduct training in Mandeville Creek.
21 August 2010
Volunteers participated in the second water quality monitoring session
of
2010.
Two volunteers conduct a
Wolman Pebble Count
to determine the nature of the stream bed.
The stream bed type affects water flow and determines the habitat for
aquatic creatures and plants.
17 July 2010
Volunteers participated in the first water quality monitoring session of
2010.
Two volunteers take stream profile data while another volunteer
discusses
procedures with the auditors from MSU.
The auditors observe to ensure that monitoring is done properly.
26 June 2010
Volunteers attended a training course to prepare for the water quality
monitoring sessions that will take place in July,
August and September
of 2010.

macroinvertbrate
samples and preserve them for labratory analysis.
19 September 2009
B2BC volunteers participated in the third water quality monitoring
session of 2009.
They are preparing to do water flow measurements.
This monitoring site is near a golf course,
so volunteers have taken to wearing head protection to guard against
stray balls.
22 August 2009
B2BC volunteers participated in the second water quality monitoring
session of 2009.
This permanent water level gauge aids in quick estimates of water flows,
but it is still necessary to do detailed water flow measurements during
the three yearly monitoring sessions.
25 Jul 2009
B2BC volunteers joined these
GGWC
volunteers doing the first water quality monitoring session of 2009.
This first monitoring session takes about 8 hours because great care
must be taken gathering
macroinvertebrate
samples in addition to the usual stream profile,
water flow and chemistry measurements.
27 Jun 2009
B2BC volunteers attended a
GGWC
refresher course to prepare for water quality monitoring sessions that
will take place in July,
August and September of 2009.
Here,
two new volunteers take stream profile measurements that will be used to
estimate the flow volume.
20 September 2008
B2BC volunteers did a monthly water quality assessment of the two
monitoring sites established on Bridger Creek.
Here,
volunteers make use of sophisticated water quality measurement tools
provided by the
GGWC
to monitor dissolved oxygen,
potential hydrogen,
particulates,
etc.
26 August 2008
B2BC volunteers did a monthly water quality assessment of the two
monitoring sites established on Bridger Creek.
Here,
volunteers are doing flow measurements by timing the progress of floats
dropped into the creek.
24 July 2008
B2BC volunteers established two monitoring sites on Bridger Creek and
spent a long day doing measurements to set a base line.
Measurements were made quite challenging by the high water levels due to
the late Spring snows and rain followed by warm weather.
June 2007 & July 2008
Several B2BC area residents participated in a
water quality monitoring workshop
held June 1st and 2nd of 2007 and July 12th of 2008.
This picture shows a field trip to Mandeville Creek on the Montana State
University campus to practice some of the measurements we take for our
own quality assessment projects.
Training sessions are conducted yearly before monitoring occurs.
