Oswego Lake Watershed Council

Friends of Iron Mountain Park

You are invited to come individually or as a family (children are welcome with parents) to help simply weed landscape areas of our new active area. The recent plantings are doing well but competing weeds need to be removed for both aesthetics in the landscape but also so that the native plants can thrive (picture above of our targeted area).

Hand pulling with or without small cultivator tools will immensely help our Parks Department staff in maintenance responsibilities.  Please contact Mike Buck to register for this Saturday’s, June 12th  work party:

Date: Saturday, June 12th
Time:  10:00am – noon
Place:  Iron Mountain Park (meet just off parking lot)

A brief orientation will be given at the beginning of this park enhancement.

covid-19 virus


Oswego Lake Watershed Council’s number one priority is the health of our community and volunteers. We appreciate all of you and want you to know that our staff is closely monitoring the spread of COVID-19 and taking appropriate measures to ensure that we are doing our part to promote wellness in the community.


Black Lives Matter

Black Lives Matter

The murders of George Floyd and Breonna Taylor at the hands of the police have reinvigorated national conversations around racial justice, and police violence against Black people. We condemn this racial violence.

Environmental justice is inherently linked with social and racial justice. We cannot have a safe and healthy watershed unless we address the conditions that harm folks who live in our community. We envision a world where a black man can hike through our local parks and birdwatch without fear of surveillance or violence. Where everyone can breathe, and have access to clean air and clean water.
