Portage Lake Watershed Management Plan

The Portage Lake Watershed Forever Committee’s 2008 watershed management plan was in need of a 10-year update.  Spicer Group compiled 10 years’ worth of watershed data and 2008 plan to develop the EPA approved 2019 Portage Lake Watershed Management Plan. Additionally, the plan was supplemented with watershed stormwater quality monitoring data that was collected by Spicer Group in 2017 and 2018 during rain events.  Spicer group was responsible for the development and execution of the stormwater quality monitoring protocol for wet weather monitoring in Onekama Township stormwater infrastructure.
