Testalinden Creek is a watercourse that flows east into the Okanagan River, south of the Okanagan town of Oliver, British Columbia. [1] The Testalinden Dam was at the headwaters of this creek prior to the dam's failure in June 2010. [2]
The dam at Testalinden Lake located near the summit of Mt. Kobau burst on June 13, 2010 at around 2:15 pm creating a debris torrent landslide that descended about 1500 m to the valley below, destroying 5 houses, damaging several farms and blocking British Columbia Highway 97. [2] The overall damages were estimated to be over CAD$20 million. [2] The dam was constructed in 1927 and was in poor maintenance at the time of failure. [2] Two days before the breach, a hiker noted that Testalinden Lake was full and the dam was overtopping. [3] After a surge of snowmelt, the dam failed, releasing approximately 20,000 m3 of water into the Okanagan Valley, which led to a debris flow with a volume of more than 200,000 m3. [3] Traffic was detoured around the debris on the highway for several days as the highway was repaired. Additionally, two of Oliver's water mains were affected by the slide, resulting in 10 homes and 750 acres of farmland losing access to water. [4] Testalinden Creek was later rehabilitated by returning it to its former channel, which was heavily armoured with rock.
On August 14, 2015, lightning caused a large wildfire in the Testalinden Creek area. [5] Strong winds quickly spread the fire, which burned 5,202 hectares over the course of a month. [6]

Mount Boucherie is a mountain located in West Kelowna on the west shore of Okanagan Lake, British Columbia, Canada, opposite the city of Kelowna. It is the remnants of a former stratovolcano created nearly 60 million years ago. Between four and six different glacial periods over the past 50 million years have eroded the volcano to produce Mount Boucherie.

Vaseux-Bighorn National Wildlife Area is a National Wildlife Area in British Columbia, Canada, primarily set aside to protect winter rangeland for California bighorn sheep. In 1979, the Vaseux-Bighorn Wildlife Area was established in response to substantial reduction in wild animal populations in the area. Identified factors contributing to species decline at the time were high predator population, overharvesting of species, and illegal hunting. Land development, cattle raising, and lumbering also might have altered species populations. Under these conditions, the area was able to be classified as a Category IV area by the IUCN and is now used for wildlife habitat and conservation. Even with minimal anthropogenic use of the area, threats persist through invasive species. Recreational use is limited spatially and is only open to the public during the day.
The 2010 Mount Meager landslide was a large catastrophic debris avalanche that occurred in southwestern British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m3 (1.6×109 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment. It was one of the largest landslides in Canadian history and one of over 20 landslides to have occurred from the Mount Meager massif in the last 10,000 years.
