Easter Lake was deemed impaired by the Iowa DNR and U.S. EPA due to high phosphorus and sediment levels. To reduce sediment and nutrients through water quality improvements, a group of project partners completed research to identify sources of pollution, areas of priority, and create a plan for restoration. The Polk County Conservation Board identified the need for a loop trail around the lake in 2006 through master planning efforts.

Project recommendations were extremely wide-ranging and involved numerous types of construction and expertise. Polk County Conservation and the Iowa DNR determined general project needs and goals before Snyder & Associates, Inc. was chosen as the civil engineer. Dividing the projects into several smaller phases allowed for manageable project contracts and contractor specialization to guide project success.

Construction activity at the lake started in 2013 with the first phase of the trail.  Subsequent phases of trail construction and lake improvement projects occurred in following years including a drawdown of the lake in 2017 and 2018 to allow final mechanical dredging, shoreline work, trail construction and construction of the signature bridge across the west end of the lake.  The lake was allowed to fill in the winter of 2019 and a grand re-opening was held in June of 2019.
