Casco Bay is healthy for now but suburban development poses a threat to wildlife and water quality.

That is the conclusion of the Casco Bay Estuary Partnership’s 2010 State of the Bay Report,  which assesses the condition of the bay and its watershed every five years.

While industry was the major source of pollution in the 986-square mile bay in the past, today runoff from roads and lawns are the major threats to water quality, the report says.

The findings will be discussed at a conference open to the public at 8:30 a.m. Oct. 21 at the Wyndham Portland Airport Hotel in South Portland. Registration information is available at 780-4820 or online at
