This power point describes the Bear Creek sampling program.

2. The Bear Creek Story

3. Introduction
In March 2011 the Bear Creek Watershed Group Technical Advisory
Committee proposed a stream monitoring project for Bear Creek, the
largest creek in the watershed. The goal of the project was to collect
water quality data that could be used to guide riparian revegetation
efforts along the creek. This work was deemed necessary to encourage
the increase in the salmonid population which had been in decline for a
number of years. The ensuring work has been conducted in
cooperation with personnel from the local California Fish and Wildlife
Office.

4. Introduction
Bear Creek Watershed is located in Shasta County, Northern California.
The watershed is northeast of Redding, east of interstate 5 and south
of the City of Shasta Lake. The watershed is 157 square miles and
approximately 40 miles long. The elevation range is from 6,740 ft. at
Latour Butte in the northeast to the Sacramento River at 360 ft. in the
south west (1).

5. Introduction
Water quality monitoring began in September 2011 and is on-going.
The focus of this poster is to present a visual representation of the
water quality measurements that have been collected to date for the
three parameters: temperature, dissolved oxygen and pH.

6. Introduction
It is hoped that this poster will help further the goals of the Bear Creek
Watershed group to: inform interested individuals about the human,
aquatic, riparian and terrestrial features of the entire ecosystem and to
assist in identifying areas in which additional data and information are
needed” (2)

7. Methodology
Sample data was collected monthly from 9/16/11 to 5/22/14. The data
consisted of eight water quality related parameters and air
temperature collected at nine sites along a 26-mile stretch of Bear
Creek, the largest stream in the Bear Creek Watershed. The water
quality related parameters measured were temperature, dissolved
oxygen DO (mg/l), DO (%), conductivity, specific conductance, turbidity
(NTU), pH, and water depth at the logger. The map to the left locates
and highlights the location of the sample points along Bear Creek.

8. Results
Data collected to date on three of the water quality parameters,
temperature, dissolved oxygen and pH are presented in the three lower
maps. The parameter values are averages for the entire sampling
period. Each parameter was mapped on background layers that
represent specific watershed elements that may affect the parameter.
Therefore, temperature was mapped on an elevation layer, pH was
mapped on soil and fire history and dissolved oxygen was mapped on
fire history and vegetation.
