A Wet End to August, 1991

Recently, we were tasked with finding more information about a flood that washed out and damaged several bridges over Fitzsimmons Creek in the 1990s.  As it turned out, the flooding had happened exactly 28 years before we looked into it, with the bulk of information found in the September 5, 1991 edition of The Whistler Question.

The first mention of an unusually wet end to August appeared in the previous week’s editorial section, where editor Bob Barnett opened a piece on government money granted in the area with the thought, “The old age it never rains, it pours, has applied to the weather this week, but also to government handouts.”  Between August 16 and 31, 155 mm of rain were reported to have fallen in Whistler, with the bulk of the rain falling between August 29 and 30.  The average rainfall for the entire month of August was historically under 50 mm; this unusually large quantity of water caused destruction throughout the Sea to Sky corridor.

During the five days of intense rain, water levels at the Pemberton Airport and the Golf and Country Club were recorded at over two metres and BC Rail recorded at least twelve places between Britannia Beach and Lillooet where the crushed rock that supported the rails was washed away, leaving sections suspended over the ground.

In Britannia Beach severe flooding caused Britannia Creek to change course through the lower townsite and the highway around Squamish was blocked for 36 hours.  According to the Ministry of Forests, three quarters of the forest service roads in the Squamish Forest District were closed from washouts, flooding or slides, with multiple bridges destroyed.  North of Pemberton, some residents around Skookumchuck were evacuated to Pemberton by helicopter.

Within the Pemberton Valley, a Friday afternoon community effort to shore p a dike behind the Van Loon property attempted to mitigate the damage caused by the flood.  Approximately 100 people were reported to have come out to fill sandbags.  Their success was limited as the dike was breached a few kilometres north of their work, flooding fields and homes and ruining potato crops.

Compared to other areas of the Sea to Sky, the flooding would appear to have caused relatively little destruction in Whistler, mainly due to the community effort to keep Fitzsimmons Creek in its channel.

Through the evening of Thursday and Friday, local contractors, excavators and heavy equipment crews worked to shore up the banks of Fitzsimmons Creek and keep the waters out of the village and White Gold.  According to Tony Evans, public safety director, “If we hadn’t had that we could have made Britannia Beach look like a walk in the park.”

As it was, the high waters and debris in the creek took out two supports of the Nancy Greene Drive bridge, partially washed out two footbridges linking the village and benchlands, and destroyed Fitzsimmons Creek Park.  The flooding also damaged sewer pipes and interrupted water supplies to White Gold.

At this time 28 years ago, Whistler and the surrounding communities were still in the midst of their clean up efforts as the water receded.  It would take weeks to clear debris, assess damages, rebuild bridges, and construct measures to prevent future flooding, such as deepening Fitzsimmons Creek.  Some of these measures can still be seen while walking across Fitzsimmons Creek today.
