Middle Shuswap Water Stewards

Shuswap River -- Oddfellows Campground

What is referred to here as the Middle Shuswap Water Stewards is actually a combination of 2 groups of volunteers calling themselves the Cherryville Water Stewards and the Middle Shuswap & Lumby Water Stewards. The Middle Shuswap watershed stretches from Sugar Lake to Mabel Lake, and encompasses all the tributaries sampled by these groups.

Analysis of the samples gathered by these volunteers is funded by the Regional District of North Okanagan.

CARO Reports

Indexes to the test results as reported by CARO, along with the Hach meter readings, are listed below.

Excerpts

The number of constituents (analytes) in each test is vast, particularly for samples tested for metals. So, for quick reference, 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. See the list at bottom of this page.

Watersheds
The data has been organized into various watershed segments, shown beginning with the upstream sampling sites in the watershed, and ending downstream.
N.B. the numbers have been transcribed by hand in most cases; refer to the data in .PDF files as reported by CARO in cases of uncertainty.

Analyte Limits
The number at the head of each table provides for quick comparison of actual values with an appropriate maximum or minimum.

The concentration of any particular analyte in the water may be appropriate (acceptable) or not depending on the purpose assumed for that water. None of the limits included here refers to drinking water, since little or no water from these courses should be drunk by humans without prior treatment. What wild animals and aquatic life  are supposed to do regarding treatment is unknown.

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

CARO Reports - Upper Middle Shuswap (Cherryville)

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 2008-2019. 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).

Cherry Creek (N. & S. Forks) (w.i.p.)

Cherry Creek, beginning as two creeks known as the North and South forks, is the largest tributary of the Middle Shuswap River. It is not a Pacific salmon spawning creek but may have been prior to the construction of Wilsey Dam at Shuswap Falls in 1929.

(*) Primary Contact Maximum :-

B.C. provincial standard for recreation with most of the body in the water and risk of ingestion (e.g. swimming).
The Canadian standard is much higher, being a count of 200/100mL.
Both references speak of the geometric mean of several samples, as opposed to single-sample maximum. The standards quoted here are for the geometric mean, a lower maximum than allowed by a single sample result.

Bessette Creek & Lumby (Harris, Duteau, Vance Creeks)

Bessette Creek is formed in Lumby by the confluence of Harris and Duteau Creeks. It is the largest tributary of the Middle Shuswap River downstream of Cherry Creek, is a Pacific salmon spawning creek, and gives the salmon access to Harris, Duteau and Creighton creeks, where they also spawn.

(*) Primary Contact Maximum :-

B.C. provincial standard for recreation with most of the body in the water and risk of ingestion (e.g. swimming).
The Canadian standard is much higher, being a count of 200/100mL.
Both references speak of the geometric mean of several samples, as opposed to single-sample maximum. The standards quoted here are for the geometric mean, a lower maximum than allowed by a single sample result.
