Dead Seagrass and Wrack Removed to Protect Water Quality in Budgewoi Lake

Tue, 21 Dec 2021 22:04:01 +0000

DEAD seagrass will be removed from Budgewoi Lake and Lake Munmorah in the coming weeks as Wyong Shire Council’s weed harvester shifts into overdrive.

Since August, a total of 730 tonnes of wrack was removed from the lake and taken to Buttonderry Waste Management Facility in Australia.

Last year, the council removed 5800 cubic metres of wrack from the shore zone next to recreational areas which would otherwise have decomposed in the lake, affecting water quality and contributing to the formation of organic black ooze.

Weed Harvesting Crew Roles and Weekly Schedule for Harvesters Barges and Transporters

The Harvesters (weed cutters) are Yellow. They are cutting on Mondays, Tuesdays, Wednesdays and Thursdays. Typically “as a rule of thumb” the harvesters do not cut on Fridays.

The Shore Barges (weed pick up – floaters and shorelines) are Orange. They are out every weekday, weather permitting, picking up floating weeds and weeds along the shoreline.

The Transporters are Blue. They are out every weekday weather permitting, and they are used for unloading Harvesters and Shore barges to transport the weeds across the lake. They hook up to the conveyor which loads the weeds into Big Red (the big red dump truck). The Transporters are also heavily utilized in pile pickups on Mondays and Fridays.

Aquatic Harvester Removes Storm Washed Lake Weeds From Rotorua Lakefront

An aquatic harvester has been working at the Rotorua Lakefront in New Zealand, removing mammoth amounts of lake weed from the shore. The large influx washed up around Sulphur Point and Ohinemutu after strong winds and heavy rain battered the region.

An influx like this was not uncommon as storm conditions could break off weed from off-shore weed beds. It happened about every four to five years.

The past two months have been productive for the Chautauqua Lake Association in New York, and the work is just getting started. July is expected to be even more productive with the expansion to a third site to efficiently maintain Chautauqua Lake’s ecology.

To date this season, the Lakewood and Long Point crews have removed 183 truck loads of aquatic vegetation from Chautauqua Lake, totaling more than 3 million pounds. Last week alone the CLA crews removed 500,00 pounds of vegetation from the lake.

Not only does the Chautauqua Lake Association use aquatic plant harvesters to cut and remove the lake weeds, but they also remove floating debris, shoreline and post-storm clean-up, plus scientific monitoring to meet lake management needs.

Curly-Leaf Pondweed Washes Ashore in Clear Lake as Its Seasonal Life Cycle Ends

Fri, 05 Nov 2021 14:53:11 +0000

In mid-June in Clear Lake, much of the curly-leaf pondweed had reached the end of its life cycle, and the weeds washing ashore are just a result of that. Curly-leaf pondweed begins to grow during the fall at the bottom of bodies of water, like Clear Lake, with its life cycle coming to an end in the late spring and early summer.

There was more curly-leaf pondweed this year than in average years because milder winter conditions experienced in Clear Lake made for optimal growing conditions for the weeds, meaning there was just a lot more of it than usual. And while curly-leaf pondweed is an invasive species, according to Cerro Gordo County Department of Natural Resources Fisheries Biologist, the weed is nothing to worry about for Clear Lake, Iowa residents and is just a harmless aquatic plant.
