PROJECT DESCRIPTION
Located less than 50 km from Montréal, the Norton Creek organic soil watershed constitutes the main source of fresh vegetables in Québec. The input of this watershed in Québec's agricultural economy is thus important, all the more since it concerns specialized cultures calling for leading technologies acquired during the last 40 to 50 years.
But, this watershed has had many flood problems during the last years, more and more frequently, resulting in considerable agricultural losses. Since the 40s, all the efforts put in making the Norton Creek watershed the granary of Québec are now faced with ravaging events that are still not controlled despite many studies and actions.
In conjunction with flood problems throughout the entire Norton Creek watershed, the conservation of organic soils constitutes another problem just as severe for market-gardening culture. A simple flood control action through drainage could lead to losses just as considerable as those generated by floods. That is why the Ministry mandated Teknika HBA to elaborate an integrated development plan allowing to get rid of floods once and for all, preserve soils and irrigate cultures during dry periods.
