What is the Marsh Creek Watershed Council?

The Marsh Creek Watershed Council is a voluntary, non-regulatory forum to achieve integrated, long-term watershed planning, management and funding, and increase communication and access to information regarding the watershed. 

Meetings are held once a month and typically alternate between virtual Zoom meetings and in-person field trips throughout the watershed. The Zoom meetings are held on the last Tuesday of the month from 4:00 to 5:30pm.

The 2025 MCWC Zoom meetings are planned to occur on January 28th, March 25th, May 27th, July 29th, and October 28th. Field trips and/or in-person meetings will be scheduled during the months between. The MCWC will not meet or have field trips during the months of August or December.

MCWC Mission, Vision, and Guiding Principles

Mission Statement: The Marsh Creek Watershed Council connects and inspires people and communities to collaborate, organize, and facilitate stewardship of a healthy, thriving watershed.

Guiding Principles:

  1. Interconnectivity: We recognize the connection between our individual selves, communities, and ecosystems. 
  2. Resilience: We aim to build the capacity of our communities and local ecosystems to be resilient in the face of natural and human caused changes.
  3. Adaptability: We practice flexibility, utilize technologies and develop resources to build a thriving watershed.  
  4. Understanding: We strive to include diverse perspectives to enable collaboration on common goals and actions. 
  5. Impact: We promote and create opportunities to educate and deeply connect our communities to nature and the watershed.   
  6. Engagement: We provide opportunities for all to learn, participate and take action.
