Tweedsmuir Provincial Park

Bulkley-Nechako E, British Columbia
Managed by The Swim Guide

BEACH INFO:
Tweedsmuir is a 981,000 hectare park, the largest provincal park in BC. For this mapping project, we will include this area in one overall view, even though the park itself contains both North and South provincial protected areas, many lakes, and many streams and rivers.

The park is near Williams Lake and Bella Coola; to get there, you may book a flight on Wilderness Airlines from Vancouver.

The park was named for the 15th Governer General of Canada, John Buchan, Baron Tweedsmuir, who had traveled the area extensively. According to BC Adventure, he stated in a book, "I have now travelled over most of Canada and have seen many wonderful things, but I have seen nothing more beautiful and more wonderful than the great park which British Columbia has done me the honor to call by my name."

The South Tweedsmuir Provincal area has a few precautions, including in January 2011, when flooding closed some facilities, and winter damage to some foot bridges on hiking trails in the Turner Lake Canoe Chain. Trails in this park are not regularly maintained, and strong caution is advised, especially during windy periods and after heavy snow and ice. Watch for fallen trees and road wash-outs. The government of BC notes that the Atnarko River can be extremely dangerous due to debris and fluctuating water. Only those with comprehensive knowledge of the river should even consider planning to trek it. At times, floods and winter damage may close boat launches, so be on the lookout. The south area consists of four ecological zones: apline tundra, Engelmann spruce/sub-alpine fir, sub-boreal spruce, and western hemlock.

The North area is considered a wilderness area, and visitors are warned to come equipped and self-efficient, as no supplies are around. Hunters must hunt only with licences, game tags, and knowledge of BC hunting laws (hunting is allowed only in the fall). Backcountry fees, such as to Eutsuk Lake and other areas, are in effect. The ecological zones in the north area are apline tundra and sub-boreal spruce.

This area has been used for thousands of years by the Nuxalk (Bella Coola) people of the coast and the Tsihquot'in people of the interior, who all have relied on the salmon in the rivers. Angling is one of the most popular draws of the park. The nearby rivers have steelhead, truot, coho, and chinook. The Dean River is well-known for fly-fishing. The lakes have dolly varden, cutthroat, rainbow trout, and whitefish.

The parks also boast a canoe chain, including the Turner Lake chain, a 19 km route through seven lakes. The canoes can be rented at Turner Lake, or airlifted in. Take note of Hunlen Falls, 260m, one of BC's highest waterfalls.

SOURCE INFORMATION

The Interior Health Authority monitors the water quality at 54 Interior region beaches. Sampling is conducted during the height of swim season (May – September).

Interior Health follows the recreational water quality criteria recommended by the the Canadian Recreational Water Guidelines. One sample is collected per beach per week. The geometric mean for each beach is calculated from the 5 most recent samples.
Recreational water is considered safe if the geometric mean result is under 200 E.coli/100mL. The single sample criteria is 400 E.Coli/100ML. Should the geometric mean exceed 200 E.coli/100 mL, or the single sample result exceed 400 E.coli/100 ML, or in the event of a known hazard or spill, the Medical Health Officer will make an assessment of the risk to human health. If there is a risk to human health, a warning sign will be posted at the beach. Results are communicated on the Interior Health Authority website (https://www.interiorhealth.ca/YourEnvironment/RecreationalWater/Pages/default.aspx). To ensure consistency, Fraser Riverkeeper calculates the geometric mean result for the Interior Health samples. We update Swim Guide according to these results, as soon as they become available.

Test results from the weekly samples for the Interior region beaches are typically posted on Fridays. Recreational water quality for a beach is determined by E. coli counts from based results collected by either the beach owner (local beach owners conduct their own beach testing and provide the sampling results to Interior Health) or Interior Health.

A beach is marked Green when geometric mean results are under 200 E.coli / 100 ML water.

A beach is marked Red when the geometric mean is equal to or above 200 E.coli / 100 ML water.

A beach can also be marked red when a single sample result is equal to or above 400 E.coli/100ML water.

A beach is marked Grey when there are no current results or there is no available information.
