Big Walnut Creek Watershed

Descriptions of Watershed Characteristics


The drainage area, stream network, and monitored stream segments for the Big Walnut Creek Watershed have been detailed by the Ohio EPA Division of Surface Water. The location of the watershed in relation the other watershed throughout the state can also be seen in the small Ohio map on the top right.
According to the Ohio EPA, the Big Walnut Creek Watershed is impaired by nutrient enrichment, ammonia, and pathogens. Similar to many of the other watersheds, the majority of the river miles are impacted by nutrient enrichment. Such severe river and stream impairments commonly result from human development, inadequate agricultural practices and land use changes in the surrounding area.
