Extent of available data.
This data layer is the Rivers and Streams component of the Hydrography data set. It was developed by the Minnesota Department of Natural Resources and includes detailed line work for rivers and streams. The location and flow direction of rivers and streams are important to understanding the potential consequences of activities on the landscape. Not only are these surface waters locally susceptible to pollution, they can effectively transport that pollution to other surface or groundwaters downstream. Due to their vulnerability and exceptional ecological and economic importance, the potential to impact them should be carefully considered.
