RDCK – 2020 Nuisance Mosquito Program Meadow Creek, Pine Ridge Executive Summary Morrow BioScience Ltd. (MBL) has now completed the 20th consecutive year as mosquito control contractor for Meadow Creek and Pine Ridge within the Regional District of Central Kootenay (RDCK). This season, 2020, concludes the 3rd year of a 5-year contract. Mosquito development site knowledge has been acquired in low and high-water years and through early and late freshet seasons. The mosquito control program reduces floodwater and snowmelt mosquito abundance within Meadow Creek and Pine Ridge. Most control activity takes place along the north side of Kootenay Lake, Pine Ridge, along the Duncan River, Meadow Creek, and the Marblehead area. Immediately preceding the mosquito season, the snowpack in the West Kootenay basin, was 118 percent of normal. Fluctuating high and low pressure systems within the West Kootenay snow basin led to a late start to the mosquito season. Secondary warming stints at the end of May triggered the melting of the majority of regional snowpack and led to the Kootenay Lake peak and the initial peak of the Duncan River. The Kootenay Lake peaked on 4 June at 533.425 m. The Duncan River first peaked on 30 May. The Duncan River’s peak in May was attenuated by the Duncan Dam; the technical peak for Duncan River occurred on 27 July (3.069 m) in response to a large discharge event from the Duncan Dam. Considerable precipitation was locally received in May, augmenting river levels beyond the natural trend of the freshet. Because the 2020 River and Lake peaks were higher than those of 2019, a compounded egg abundance existed within mosquito development sites. This caused a greater number of mosquito eggs to hatch than would have hatched under normal environmental conditions. Accordingly, more concern calls and emails were received than in 2019, or other low-water years. No human-case of West Nile virus or Zika were reported by the CDC in 2020. Between 21 April and 4 August, a total of approximately 716.4 hectares were treated by ground and helicopter. This total is approximately 450 ha greater than the total of hectares treated in 2019. Treatment efficacy was assessed as high. Three aerial events targeted floodwater mosquito development sites associated with the Kootenay Lake and Duncan River flood plains. A real-time monitoring and treatment data dashboard was provided to the RDCK program manager. The dashboard enables the program manager to view up-to- date treatment information and ensure quality control. Communications with residents remains a priority for MBL. Although no interviews specific to the Meadow Creek and Pine Ridge mosquito control program were requested in 2020, a media release was published on various

Kootenay Lake Ferry Map Kootenay Bay to Queens Bay sailing distance is 5.4 km Kootenay Bay to Balfour sailing distance is 8.8 km The Opportunity • Relocate the Balfour ferry terminal to QueensBay and improve safety, reduce emissions, improve service, reduce operating costs for 9,000,000 ferry users over the next 25 years. • In addition, a smaller ferry can be built and would be able, due to the significant reduction in crossing time, to surpass the car carrying capacity of the new proposed 60 car ferry during a major transportation disruption of the Kootenay Pass. • It would improve the economic and societal benefits in the Kootenay region Project Review Balfour terminal • A new ferry is required for both scenarios since the Balfour ferry needs to be decommissioned and the Osprey 2000 will need to be refurbished in 2023. • The Balfour ferry terminal needs to be refurbished, with a large parking lot extension over green space. Minor improvements at Kootenay Bay. • No significant improvement in service since travelling time remains the same.
