Title: Central WI assessment: Using available GIS data to evaluate regional hydrologic alteration and opportunities
Abstract: Working with WWA, EOR has completed the first stage of a regional assessment of hydrologic conditions and restoration opportunities in Wisconsin's Central Sands region. The objective of this work was to directly identify trends and opportunities across the Central Sands region using available, largely state-wide GIS data. We also aimed to develop a framework for to apply to similar assessments in other regions of Wisconsin. We documented and obtained all known applicable data sets, conducted GIS statistical analysis at the HUC-12 and county scales, and created a web map for internal collaboration and discussion. We learned that while the Central Sands is a large and diverse region, key patterns in natural landscape features and human hydrologic alterations can be teased out of the available data. In particular, we have identified several subregions that contain overlapping stressors, and we will work to identify potential restoration opportunities and conduct detailed assessments of these areas during the project's second stage.
