Weed prob­lem

The Glengarry News - - Straight Talk - BY STEVEN WARBURTON News Staff

Sick of the seaweed while swim­ming at Is­land Park? Don’t you fret. North Glen­garry Town­ship will be­gin ad­dress­ing the sit­u­a­tion as of this Fri­day.

“The Town­ship of North Glen­garry rec­og­nizes that while the wa­ter lilies in Mill Pond are pretty when they’re bloom­ing, the al­gae and Canada wa­ter­weeds cre­ate less than ideal swim­ming con­di­tions,” said Tara Kirk­patrick, North Glen­garry’s Com­mu­ni­ca­tions Of­fi­cer, by way of a June 11 press re­lease. “We re­main com­mit­ted to an ag­gres­sive strat­egy to re­duce weeds in Mill Pond.”

The town­ship uses a weed har­vester, which it pur­chased in 2016, to deal with the weed sit­u­a­tion. The bright orange ma­chine is ca­pa­ble of nav­i­gat­ing through shal­low wa­ter at a slow crawl and re­mov­ing weeds with ex­treme care. It is oper­ated by a sin­gle driver who cir­cles the lake in ro­tat­ing pat­terns. The weeds col­lected are de­posited on the shore­line and re­moved for composting.

Ms. Kirk­patrick says that the weed re­moval is done in a way that im­proves the lo­cal ecosys­tem.

“By re­mov­ing nu­tri­ents from the lake (the weeds), we im­proved the fish habi­tat by pro­mot­ing an in­crease in dis­solved oxy­gen for aquatic life,” she says. “The har­vester pulls weeds from depths up to around five feet and col­lects them for re­moval from the lake.”

“If we were to sim­ply cut the weeds and al­low them to sink to the bot­tom of the pond, we would be re­turn­ing nu­tri­ents to the lake bed, which would aid in the pro­lif­er­a­tion of the Canada wa­ter­weed.”

The Town­ship will en­sure that spawn­ing fish’s nests are well iden­ti­fied prior to the re­moval of the weeds.

Canada wa­ter­weed is an in­va­sive and adapt­able peren­nial plant that thrives in both mov­ing and still wa­ter. It usu­ally grows hor­i­zon­tally, form­ing a dense car­pet of weeds. Al­though it sometimes reaches the wa­ter sur­face, this nui­sance plant usu­ally main­tains stems and leaves that are com­pletely sub­merged.

The Town­ship re­ceived a Let­ter of Ap­proval to be­gin the work af­ter dis­cus­sions with the Depart­ment of Fish­eries and Oceans along­side the Raisin River Con­ser­va­tion Author­ity.
