Structures a home for sea creatures

It’s a cold crisp Saturday morning in mid-January and the ice off the north boat landing on Cedar Lake is alive with the sounds of chain saws and Bobcats.

On the horizon, shantytowns harbor diehard fishermen trying their luck through 16 inches of ice. However, the largest and loudest population on the ice this morning consists of volunteers from Star Prairie Fish & Game and the Cedar Lake Management District, along with concerned local anglers, who are working together with staff from the Wisconsin Department of Natural Resources constructing 45 new fish cribs.

John Bush, a volunteer from SPF&G, sits behind the wheel of a four wheeler waiting for a crew of his fellow volunteers to position one of the completed cribs on his sled. His job is to tow cribs to one of three staging areas located on the south end of the lake.

Wearing a fashionable blue hardhat and bright green safety vest, Barbara Scott with the DNR props herself up against several rods of rebar.

Surrounding her are numerous cribs in various stages of completion. They look like miniature log houses with no roofs stuffed full of brush and tree branches.

Scott explains part of the process; The logs are placed on top of each other leaving about an eight-inch gap between each layer.

“Once the logs are in place, we bend the tops of the rebar over to hold it all together,” Scott said. “Then we place branches in between the layers to create the fish habitat. After the cribs have been towed into place, we tie cinder blocks on top to prevent them from moving once they sink.”

The cribs will sit in place out on the ice until spring thaw. As the ice melts, the cribs slowly settle into place at the bottom of the lake.

Fish techs from the DNR were out on the lake in the fall determining the precise locations where the cribs would be located.

Daryl Berg, with a pipe in hand, is hard at work bending rebar. Besides being a self-appointed “log loader and brush builder,” Berg is a local fisherman who makes time to help with this project because he “cares about the fish habitat.”

Marty Engel is a biologist with the DNR’s Lower Chippewa and Central Wisconsin Fisheries Team. He operates out of the DNR office in Baldwin and this morning he’s in charge of making sure the cribs are correctly constructed and delivered to the correct locations. The plan is to sink up to 500 cribs throughout Cedar Lake over the course of the next 10 to 20 years.

“Cedar Lake is clear enough to grow weeds in the spring, but by around June 15th, the algae begins to come on strong. When the lights go out, the plants don’t grow,” Engel said. “By mid-July the weeds are starting to die back and by August they’ve all but died off. Cribs are one way to create alternate habitat in green lakes.”

Creating log cribs provides a place for fish to migrate to when the weeds die off. According to Engel, the center of the cribs provides cover for smaller fish like bluegills, perch and crappies, while the extended branches on the perimeter provide hunting areas for larger species like northern pike, walleyes and muskies.

“Once they go through the ice, fish will gravitate to them instantaneously,” he said.

The results of the project have been promising.

“There wasn’t a lot of good pan fishing on this lake 10 years ago,” Engel recalls, “But now you can tell the results just by seeing the number of ice shacks out on the lake and talking with the people.”

Ever wonder why all the shacks seem to congregate in just a few areas on the lake? Individual cribs are installed in “colonies” to mimic habitat like a weed bed.

By the end of the day, Cedar Lake will be home to numerous colonies consisting of 325 individual cribs. The fish, both predator and prey, move to where the colonies are. The fishermen follow the fish resulting in a landscape of shantytowns right on top of the cribs.

Marty reports that the DNR working in conjunction with several other volunteer groups, including students from Somerset High School, is starting crib construction initiatives on two other local lakes, Bass and Glen. In addition to the winter crib construction programs, the DNR will also be creating “near-shore” structure on Bass Lake once the water opens up by dragging 80 oak trees out into the lake so that the crowns of the trees rest in about eight feet of water.

HIGH PRAIRE, ALBERTA–(Marketwire – Jan. 31, 2012) – On January 26, 2012 in the Provincial Court of Alberta, R.J. Williscroft Contracting Ltd. pled guilty to one count of a violation of subsection 35(1) of the Fisheries Act for “the harmful alteration, disruption, or destruction of fish habitat“. The defendant was ordered to pay a fine and penalties totaling $90,000. The charge related to a project proposal by Shadow Creek Resort Inc. (owned and directed by Mr. R.J. Williscroft) to construct and connect an inland marina and approaches in the community of Joussard, Alberta to Lesser Slave Lake, via a dredged channel.

The Court heard that on September 15, 2008, an environmental consultant sent applications on behalf of “Shadow Creek Resort Inc. c/o R.J. Williscroft Contracting Ltd.” to various federal and Alberta government departments, including Fisheries and Oceans Canada, for approvals related to the construction of a proposed inland marina development on the south shore of Lesser Slave Lake. Fisheries and Oceans Canada concluded that the proposed works would likely result in the harmful alteration, disruption or destruction of fish habitat, thus an authorization and environmental assessment would be necessary. The environmental assessment began in October 2009. Aboriginal consultations with potentially affected First Nations and Métis groups began in December 2009. In the spring of 2010, Fisheries and Oceans Canada was notified of alleged works being conducted in the lake by the defendants prior to the environmental assessment and consultation process being complete, and prior to a Fisheries Act authorization being issued. The excavation of the lakebed removed aquatic vegetation and lakebed substrate and damaged spawning and rearing habitat for many Lesser Slave Lake species of fish, including Northern Pike, Walleye and Yellow Perch. Lesser Slave Lake sustains a valuable commercial, recreational and Aboriginal subsistence fishery.

At the request of Fisheries and Oceans Canada, the Court ordered a fine of $8,500 to be paid under subsection 40(1) of the Fisheries Act. Two penalties were also ordered by the Court. An amount of $500 will be paid to the Alberta Conservation Association for the creation and installation of a sign to educate the public about the fish species in Lesser Slave Lake. A total of $81,000 will be paid into Environment Canada’s Environmental Damages Fund and will be used to hire an environmental consultant to consider ways to enhance fish habitat in the inland marina and to conduct a monitoring project in the inland marina. The remainder of the penalty will be used to conserve and protect fish and fish habitat in the Lesser Slave Lake watershed.

Prior to undertaking work in or around water, Fisheries and Oceans Canada encourages the public to avoid the potential for any harmful impacts to Canada’s fisheries by ensuring they have obtained and are in compliance with all necessary permits, approvals or authorizations from municipal, provincial, and federal agencies and authorities.

FOR BROADCAST:

Fines were handed out in provincial court today after R.J. Williscroft Contracting Ltd. of Alberta pled guilty to damaging fish habitat in Lesser Slave Lake. The defendant was ordered to pay a total of $90,000 in fines and penalties for violating the federal Fisheries Act. Fisheries and Oceans Canada has requested that $81,000.00 of the penalties be directed to Environment Canada’s Environmental Damages Fund for fish habitat enhancement and monitoring in the inland marina and area.
