Tributaries

The Nanaimo River has three main tributaries and several smaller ones. The North Nanaimo River, often referred to as ''North Fork'', starts south-west of Okay Mountain (49°11′9″N, 124°13′47″W) and travels south and joins with the Nanaimo River at the outflow of First Lake. The South Nanaimo River, often referred to as ''South Fork'', starts at Rheinhart Lake (48°57′51″N, 124°5′17″W) and flows north and meets the mainstem a short distance downstream from the North Fork. Almost the entirety of the South Fork watershed is restricted to public access as that's the source of Nanaimo's water. The watershed itself is 230 square kilometres and is privately owned b
Timberlands
An agreement between Timberlands and the city of Nanaimo was formed to safeguard the drinking water supply. Haslam Creek is the other main tributary. Its source is only a short distance east of South Nanaimo River's source, Rheinhart Lake. While South Nanaimo travels north to meet the main stem, Haslam Creek flows east-northeast to meet the Nanaimo River near the Nanaimo River Fish Hatchery and Nanaimo River Regional Park.

Harmac Pacific
Two other man-made lakes, Jump Lake and South Fork Reservoir, are operated by the city of Nanaimo and supply water to Nanaimo and the surrounding area. Other notable lakes in the watershed include Blackjack Lake, Quennell Lake, Michael Lake, Crystal Lake, Blind Lake, and Whisky Lake.


Jump Lake Dam

along the course of Jump Creek, which starts at Butler Peak and flows northward where it meets the South Nanaimo River at the same spot as east flowing Dunsmuir Creek. Jump Lake Dam was built in 1974 to create a stable source of drinking water for Nanaimo and area. It can hold 17 million cubic metres of water, which is enough to supply every home in Nanaimo for a year. Water levels in Jump Lake are regulated so that downstream South Fork Reservoir remains at full supply level all the time and other reservoirs downstream have a constant supply of water.


South Fork Dam

Farther down stream, along the South Nanaimo River, about where Whisky-jack Creek meets South Nanaimo River, is South Fork Reservoir. South Fork Reservoir was created in 1931 with the completion of South Fork Dam. The dam is 50.3 metres (165 feet) wide and 30.5 metres (100 feet) tall and is built of unreinforced concrete. The reservoir holds 2 million cubic metres of water and it is kept full as Nanaimo's water delivery system is gravity fed. Two pipelines, one 750 mm and the other 1200 mm in diameter, carry water downstream to Nanaimo, where there are additional holding reservoirs. The 750 mm pipeline was built in 1954 and has a capacity of 50,000 cubic metres of water a day. The other pipeline was completed in 1993 and has a capacity of 190,000 cubes a day. In 2000, South Fork Dam was upgraded to produce

for local uses. There are nine balancing reservoirs located throughout the city to meet peak domestic demand. The first balancing reservoir was built at Lost Lake in Nanaimo's north end in 1969. That was followed by reservoirs at College Park and Rutherford Road. During the 1980s, additional reservoirs were built at Duke Point Industrial Park, Langara Drive, and Tanya Drive. More recently, another reservoir was added near
