Marsh drawdown planned at ice out

Like most ecosystems, wetlands are dynamic and need constant change to thrive.

The Broughton Sheboygan Marsh Strategic Management Plan 2013 outlines and directs the use of drawdowns every five years as a management tool for Sheboygan Marsh.

On a controlled and managed wetland restoration, such as at the Sheboygan Marsh, drawdowns mimic natural drought cycles which occur onnatural wetland ecosystems.

The 2017 drawdown will start on or around March 15 or after the ice has thinned too much forsnowmobile travel.

The benefits of a drawdown are numerous and are primarily related to vegetative and wildlife health.

However, the benefit that generates the most attention is the cost to remove floating cattail mats that tend to start to back-up behind the dam after about five years post-drawdown.

In 2016, well over 700 loads of cattail mats were removed from behind the dam, a sure sign it is time again for a drawdown. The last drawdown took place in 2011.

The duration of the drawdown lasts throughout the summer and early fall.
