Rough Fish Management and Wild Rice Restoration

Upper Clam Lake (Burnett Co., WI) has a documented history of supporting large, dense stands of northern wild rice (Zizania palustris). However, in 2006 wild rice declined dramatically throughout the lake. Unlike the periodic, temporary rice declines that occasionally occur in regional lakes, the decline of rice in Upper Clam Lake was particularly severe and it persisted for 8 years (2006 to 2013). Previous studies have clearly identified carp as the primary cause of the observed decline of rice stands in Upper Clam Lake.
In 2010, the most substantial remnant stands of wild rice were found in a large shallow bay on the southern end of the lake (~80-acre bay, mean depth <1 m). Rice stands in this bay were very sparse and generally isolated to extremely shallow areas immediately along shore. As a part of the ongoing wild rice monitoring and management activities in the lake, staff from St. Croix Tribal Environmental Services installed nets across the opening to this southern bay to exclude carp during the open water period in 2011, 2012, and 2013. These nets were left in place from May through September of each year. Assessments were completed to record late-summer distribution and density of rice growth in the bay each year from 2010 through 2013. Additionally, carp removal efforts over several years have removed an estimated 800,000 pounds of carp from the Clam Lakes since the process started in October of 2010. This talk reviews the monitoring methodology and findings from these surveys and gives an update on how the rice beds have responded to management.

Watershed Connections/Water Quality - Friday, 1:30-2:30 pm

Watershed Management & Use of BMP’s in Various Land Use Settings: 

Silver Creek Pilot Watershed Project at NEW Water

NEW water, the brand of the Green Bay Metropolitan Sewerage District, is leading a project in Silver Creek to evaluate if it is more cost effective to spend over $100 million on wastewater treatment plant phosphorus improvements or to work with agriculture to reduce phosphorus delivery to Green Bay. NEW Water is partnering with the local community to effectively execute an agricultural based Adaptive Management pilot project in the Green Bay area. The pilot study is utilizing innovative tools to execute field-level assessments, gather soil and water data, work closely with landowners and growers, and leverage local agronomist experience to target the most effective practices. The pilot will review potential frameworks for implementing a future full-scale Adaptive Management program to achieve continued permit compliance for NEW Water.

1. Partnerships are essential for successful watershed efforts.
2. Landowner and grower trust is critical to success.
3. Cover crops are very effective.
