1 – Two new invasive species have been found in Michigan waters

Staff from the state Department of Environment Quality have confirmed a freshwater alga commonly known as didymo (di di-mo)  – or rock snot – growing in extensive mats in the St. Mary’s River near Sault Ste. Marie.

Also recently discovered were New Zealand mud snails in the Pere Marquette River near Ludington.

Didymo is a nuisance algae that thrives in cold, clean water. It can grow into thick mats that cover the river bottom. The algae is not a threat to human health, but it can crowd out biologically valuable algae and important food for fish. It also can interfere with fishing and wading.



New Zealand mud snails are about an (1/8) eighth of an inch long. But they cluster together, and compete with native snails for food and space.

State agencies want to remind anglers and boaters to clean, drain and dry their equipment to help prevent the spread of didymo, New Zealand mud snails, and other types of aquatic invasive species.

3 – 
Michigan has a new Web-based system designed to streamline the process of obtaining federal environmental permits.

The MiWaters system replaces more than 25 applications and databases, some of which were more than 30 years old.

Officials say MiWaters simplifies the process for permits dealing with aquatic nuisance control and wastewater, stormwater and groundwater discharges.

It also includes electronic reporting of untreated or partially treated sanitary wastewater.
