Porter County historically has received on average 40 inches of annual rainfall. Over the last three years, annual rainfall increased to an average of nearly 50 inches (1). Lake Michigan, north-most Porter County, has reached peak elevation levels that were last recorded in the late 1980s (2). These factors play into what the citizens of Porter County have been experiencing: wetter seasons and changes in property care.
With more rainfall and high water levels, the Department of Development and Storm Water Management has received a year’s worth of drainage concern reports in the first six months of 2020. Many property owners have reported experiencing more water presence these last few years which aligns with the high rainfall trend.
