Entities Look to Acquire Hundreds of Acres Around Delavan Lake
Entities with an interest in Delavan Lake are embarking on a project to create a buffer zone around the lake that one local official believes could be as significant as the $40 million lake drawdown of 1989.

The town dredged the Inlet in 2011, removing 45,000 cubic yards of phosphorus-laden sediment. It plans to dredge the Mound Road ponds, which were built as part of the $40 million lake rehabilitation project, again next year and has also dredged Brown’s Channel.

Officials are working toward a plan to acquire additional land around the lake to create a larger buffer for run-off into the lake. The plan would involve acquiring hundreds of acres around the lake that would take farmland out of production and improve water quality in the lake.

Ecological Value of Exotic Water Plants Equals that of Indigenous Species - If you look at the role of exotic water plants in an ecosystem, you won't find any significant differences compared to indigenous species. Researchers studied seven essential functions of water plants in experiments with indigenous and non-indigenous species. They looked among other things at the impact of the plants on the habitat and food supply of fish and small aquatic animals, on cyanobacterial growth and on greenhouse gas emissions. What they found was that all things considered, the two groups are not fundamentally different.
