WATERSHED UPDATE – APRIL 15, 2021
- The snow course sampling sites were absent of snow and the consensus among the surveying organizations is that no further snow course sampling is expected.
- Current forecasts over the coming 7 days show daytime temperatures ranging from +4°C to +10°C, with minimal precipitation forecasted.
- OPG’s reservoirs on the Upper Mattagami River (Mesomikenda, Peterlong, and Mattagami Lakes) continue to fill, with consideration being given to the maintenance of minimum flows downstream for fish spawn. An earlier than normal refill was initiated at all upstream reservoirs to account for lower than normal snow amounts and inflows. Refill is also ongoing at Wawaitin GS (Kenogamissi). Forecasts and conditions will continue to be monitored and adjustments will be made accordingly. OPG’s water level and flow graphs are updated daily and can be found at www.opg.com/river.
- Town Creek, Crawford Creek and other area watercourses are flowing well. All watercourses will continue to be closely watched by Authority and Municipal staff. Stream flows and water levels continue to be monitored on a daily basis.
Further updates will be issued as required.
