Iowa DNR to Discuss Silver Lake Restoration Plan
Posted: 10/04/2011
VENTURA, Iowa - The Iowa Department of Natural Resources is hosting an open house to discuss plans to restore Silver Lake, in Worth County.  The open house will be held on Oct. 10, from 6:30 to 8:30 p.m., at Kuennan’s Quarry Shelter House, about two miles south of Northwood on Hwy. 65, then east on 450th Street. 

The Iowa DNR will unveil plans to improve the water quality, replace the dam, and restore the fishery at Silver Lake. Staff will be on hand to discuss the project and answer questions during the informal meeting.
“We have had tremendous success improving shallow natural lakes and wetlands by restoring the ecological health,” said Greg Hanson, wildlife management biologist with the Iowa Department of Natural Resources Ventura office.  The DNR and its local partners have used similar approaches in restoring Diamond Lake, Jemmerson Slough, Twelve Mile Lake, Big Wall Lake and others across North Iowa since 2004.

“The timing is favorable for restoring Silver Lake now because the dam is scheduled to be replaced, the fishery is in a state of decline after two consecutive winter fish kills, and the lake has poor water quality,” Hanson said.
Once a shallow lake is in a degraded state, its water quality will remain poor unless intensive management is implemented.  The Silver Lake plan includes dewatering the lake for 18 to 24 months while the dam is replaced and eliminating the rough fish.

“By drawing down the lake, we are simply trying to replicate the natural drought process that no longer happens frequently enough due to our altered landscape,” said Hanson. 

The lake will be gradually refilled and stocked with northern pike and yellow perch.
