Wild celery

The Delavan Lake Sanitary District has extended pier pick ups this season and will be extending the actual harvest season due to excessive plant growth this season. The wild celery has begun propagating for the year and is forming large mats on the lake, this is the plants natural cycle and is easily seen by the root system visible within these floating mats, the root system appears as white nodes that can protrude above the water line. We are speculating that the excessive growth this year may be due to heavy rainfall events this spring that contributed to larger runoff events than we’ve seen the last few years. We are currently on pace to have a record harvest this season with a greater volume of aquatic plants taken out of the lake since the inception of the harvesting program. We are working diligently to address the ever changing conditions that are associated with Lake Delavan.
