Flood Review Makes 65 Recommendations

Mar 14, 2018 | 12:37 PM

An independent review of last spring’s flooding in BC has made 65 recommendations to improve the province’s response.

Associated Environmental Consultants looked at what could have been done differently to reduce the flooding impacts, which included properties on Okanagan and Kalamalka lakes.

The report says the main cause of the flooding was a wetter than normal spring — combined with high snowpacks, and unusual weather conditions the previous fall and winter.

The review doesn’t cast blame on how the systems were managed, or the decisions that were made, but does make recommendations centred around staffing levels, experience and training, and streamflow forecasting models related to climate change.

“High inflows to Okanagan Lake, Kalamalka Lake and Nicola Lake in the spring of 2017 were part of a general pattern of high flows in creeks and rivers in this area of B.C. that resulted in widespread flooding due to high lake levels, a high groundwater table and high streamflows,” says a government release. “The high flows resulted from a combination of high elevation snow melt and above-average rainfall. Both Okanagan and Nicola Lakes experienced their highest May inflows on record.”

The Ministry of Forestry and Lands says it has already started implementing some of the report’s recommendations and is developing an action plan to address the remaining recommendations.

The flooding led to about 2.500 people having to evacuate their homes, while thousands more were on evacuation alerts.
