CARO Reports see page bottom
Indexes to the test results as submitted to and reported by CARO (Kelowna), along with the Hach meter readings where available, are listed below.
Cherry Creek, Bessette Creek and Upper Middle Shuswap River Watersheds see page bottom
The number of constituents (analytes) in each test is vast, particularly for samples tested for metals. So some analytes have been selected as important or interesting, particularly if they have tended to exceed published limits with regard to the requirements of aquatic life or human recreation. They have been displayed in three watershed groupings from upstream to downstream.
N.B. The British Columbia provincial government has an excellent web site for tables of standards and discussions of what they are based on. http://www2.gov.bc.ca/gov/content/environment/air-land-water/water/water-quality/water-quality-guidelines/approved-water-quality-guidelines
Below is a list of posts with attachments as received from CARO Analytics Services. The attachments show the analyses for each of our sampling days throughout the years since 2008. On some days, analyses were augmented to include metals.
Every sampling day we also used a Hach meter (thanks to Claude Labine) to measure the water's oxygen content at each location, by immersing the Hach probe in the stream and reading the milligrams per litre (mg/L) displayed by the meter. The readings are (in the process of being included) in the posts, along with the water temperature, the air entrainment percentage, and the atmospheric pressure, from which the meter calculates the Dissolved Oxygen (DO).
Test results from the Upper Middle Shuswap River, Cherry Creek and often including Reiter & Ferry Creeks:

At the Harris Creek site the large bottle was lost downstream. We used the bottle from the Duteau set, and the next day (Monday) removed a bottle from the set slated for use in August, filled it at the Duteau site and sent it to CARO. Hence 2 reports. A third report appears to be an (unsuccessful)attempt by CARO to provide a concatenation.

The Middle Shuswap River begins at Brenda Falls on Sugar Lake and empties into Mabel Lake, It has serveral tributaries, among them Reiter, Cherry, Ferry and Bessette Creeks. Only Bessette Creek contains spawning pacific salmon, because of the Hydro Dam at Shuswap Falls.
