New Program Aims To Rid Hatzic Lake Of Invasive Plant

By October 21, 2016Life

Submitted. The Ministry of Forests, Lands and Natural Resource Operations is taking the first step to eradicate an invasive aquatic
plant in Hatzic Lake that could create problems for local water management systems and interfere with swimming, fishing and boating
activities.

Flowering rush (Butomus umbellatus) also has a negative effect on water quality and degrades fish and wildlife habitat. Hatzic Lake covers over
290 hectares and is a popular destination for people who enjoy swimming, fishing, canoeing and other recreational water sports.

The B.C. government has committed $86,845 to the Invasive Plant Early Detection Rapid Response Program to control the spread of flowering
rush within British Columbia, which includes the initial stages of the two-year Hatzic Lake Aquatic Invasive Plant Action Plan.

The Hatzic Lake Aquatic Invasive Plant Action Plan is specifically designed to stop the spread of flowering rush, which grows quickly to
form dense patches of vegetation that can crowd out native plants and disrupt ecosystems. The current infestation in Hatzic Lake represents
the largest of only three known populations of flowering rush in B.C., so this location represents an ideal opportunity for eradication.

The treatment methods and equipment that are being tested this fall will help guide future aquatic invasive plant management in Hatzic
Lake, its connected waterways and other bodies of water in B.C.

The Hatzic Lake Aquatic Invasive Plant Action Plan consists of several phases that will last through the fall of 2017. This year’s planned
activities include:

* preliminary testing of suction dredge equipment and removal methods (in Bouchie Lake in the Cariboo) for the effective treatment of
flowering rush in the Hatzic Lake area

* an information session with the Dewdney Area Improvement District, lakeshore residents and other stakeholders in the Hatzic Lake area

* full-scale testing of suction dredge equipment in part of the Lower Hatzic Slough

* review of options for the design and installation of a containment system to stop the spread of invasive aquatic plants from Hatzic Lake
to the Fraser River

* preparations for a phased removal of invasive aquatic plants from Hatzic Lake in 2017
