Weed Harvesting Helps Control Hybrid Watermilfoil in Lake Hallie

Tue, 21 Dec 2021 21:40:36 +0000

Lake Hallie Lake Association is making some headway in the war they’ve been waging against the hybrid watermilfoil weed.

First discovered in Lake Hallie in 2005, watermilfoil is an invasive aquatic plant that has an aggressive tendency to form a thick mat-like layer as it floats on the water. If left unchecked, this plant can cover huge areas of water, blocking sunlight from reaching more desirable plants and making boat traffic difficult.

Using a weed harvesting machine, the Lake Association harvests from May to September, multiple times per week. Over the course of the season, from 200-300 tons of the plant are removed from the lake.

Fox Lake Plan Uses Harvesting and Herbicides to Manage Nuisance Weeds Near Piers

Fri, 05 Nov 2021 19:01:53 +0000

In recent years Fox Lake in Wisconsin has responded to a decade of water quality management that has shifted the lake from being turbid with frequent algae blooms to a clearer water condition.

This has fostered improved lake use, the return of aquatic plants and a more balanced fishery. One consequence of the water quality improvements is that some homeowners are experiencing nuisance levels of plant growth in front of their piers, inhibiting navigation to open water.

To address aquatic plant problem areas, the Fox Lake Inland Lake Protection and Rehabilitation District has developed an Aquatic Plant Management Plan that includes the mechanical harvesting of navigational channels to access open water and an herbicide treatment plan to create a path between the pier area and harvested channels.

Prop Chop Spreads Eurasian Milfoil in Black Lake as Officials Debate Control Options

Fri, 05 Nov 2021 15:44:30 +0000

County legislators are considering providing some type of support to a group trying to get rid of the Eurasian milfoil infestation in Black Lake, New York.

The milfoil problem is exacerbated when propellers on boats going through the lake chop it up (prop chop) the and spread its seeds. Legislators debated what methods could stop that. One group wants to dig a 50-foot channel to keep the propellers away from the milfoil. Another method could be to rent a machine that mechanically harvests the milfoil.

Donations Help Fund Weed Harvesting and Lake Maintenance at Public Boat Launches

A public boat launch doesn’t necessarily make access to a lake free. There are costs involved in keeping the waters weed free, navigable for recreation and stocked with fish. McDill Inland Lake Protection and Rehabilitation District’s president Krista Olson asks people visiting any lake to utlize the donation boxes. Those donations are very important for the lake!

McDill Inland Lake P&R District kicked off the 2021 weed harvesting season on June 11th. The harvester chops and collects weeks 30-40 hours a week so boats can navigate through the water. The harvester will collect about 14 loads weekly.

Iowa Crews Harvest Nearly 1 Million Pounds of Curlyleaf Pondweed to Clear Boat Lanes

Tue, 19 Oct 2021 20:48:31 +0000

With all of the rainfall over the past three weeks or so, the topic of curlyleaf pondweed has kind of taken a back seat. However, as we enter the month of July, it is a good time to reflect on the results of the 2018 curlyleaf pondweed treatment and harvesting process.

Mechanical harvesting of East Okoboji and in Lower Gar (Iowa) initially began on May 13, but it was halted until May 16 to get more weeds closer to the surface.

During the 3½ weeks of mechanical harvesting, 321 loads of cut curlyleaf were transferred to shore with 200 cubic feet per load. The weight of the harvested (wet) curlyleaf was 15 pounds per cubic feet. This led to a total of 963,000 pounds of wet weight!

In all, more than 41 acres of boat lanes were cut with all of the curlyleaf hauled to shore and taken to a DNR approved dumpsite. Once the dumped curlyleaf has dried out, at least 80 percent will be ground up and mixed in a compost for use on gardens, etc.

Dane County Weed Harvesters Cut Dense Aquatic Plants to Improve Navigation and Reduce Flood Risk

Tue, 19 Oct 2021 17:50:42 +0000

Floating weed harvesters have opened passages through Dane County Wisconsin’s dense tangles of underwater plants for about 50 years.

The barges wield rotating cutting bars like those on farm combines to cut a submerged crop that is fertilized too well by runoff of nutrients like dairy manure.

Each spring, the county launches a flotilla of 10 paddle-propelled aquatic mowers to cut and remove thousands of tons of soggy vegetation to improve navigation and reduce flood risk.
