Illinois Streams Filtered by Flow Volume
Our team has worked to create a multi-scale repository of stream data for the state of Illinois. This project combines stream data from across 13 USGS HU-4 subregions and uses simplification techniques, such as filtration and the use of simplification algorithms, to enable all users to have access to stream data for the state of Illinois. We currently provide seven different levels of filtration, which enable the user to further filter the data in multiple possible ways.
