Areas of shallow fog have developed across portions of northwest Indiana early this morning, with some patchy dense fog along and south of Indiana State Route 14. This includes the Interstate 65 corridor from Rensselaer southward. Localized visibilities as low as a quarter mile or less are possible. Visibilities should gradually improve from north to south prior to sunrise however, as light north winds bring drier air into the region. However, if driving across the area during the predawn hours, be alert for rapidly changing visibility conditions.

Weather today, Tomorrow,

The river has several potential tributaries and dams that could affect its hydrology. Seasonal trends show that the river experiences high flows in the spring due to snowmelt and rainy weather, while summer and fall typically have lower flows. An interesting fact about the Iroquois River is that it is one of the few rivers in the US that flows northward. Overall, the stream gauge data can provide valuable information for understanding the hydrology of the Iroquois River and its impact on the surrounding ecosystem.
