January, 2017

Precipitation

January 2017 Indiana precipitation was generally at or above normal, with average temperature above normal. The statewide monthly precipitation average was about 144 percent of normal. The overall monthly temperature average for Indiana was 33.7 degrees Fahrenheit or about 7.7 degrees above normal.

Eight of Indiana’s nine climate divisions received well above or above normal precipitation for the month of January, and the remaining division received near normal precipitation. Climate Division 3 (NE) received the highest (200.0) percentage of normal precipitation for the month, while Division 7 (SW) received the lowest (99.0) percentage.

For the 2017 water year, which began October 1, 2016, total precipitation is below normal for seven of the nine climate divisions and above normal for Division 1 (NW) and Division 3 (NE) received above normal precipitation. Precipitation for the water year ranges from 71.7 to 111.7 percent of normal. Starting from January 2016, each of the state’s nine climate divisions has received near or above normal precipitation. These range from 98.4 percent for Division 2 (NC) to 114.2 percent for Division 1 (NW).

For the Standardized Precipitation Index (SPI) long-term 12-month index, one of Indiana’s nine climate divisions is in the “very wet” category, two in the “moderately wet” category, and the remaining six divisions are in the “near normal” category. The 6-month index shows one division in the “very wet” category, two in the “moderately wet” category, and the remaining six divisions lie in the “near normal” category. The 3-month index shows the entire state in the “near normal” category. The 1-month index shows one division in the “very wet” category, three in the “moderately wet” category, and the remaining five in the “near normal” category. 

U. S. Drought Monitor

The period ending January 31, 2017 shows no drought conditions for the entire state. The U.S. Seasonal Drought Outlook does not predict drought conditions through April 30, 2017. .

Streamflow

Mean monthly flows for all twelve monitored streams were well above their historical mean monthly flow for the month of January. The White River near Alpine had the lowest mean monthly flow at 113 percent. Fall Creek near Fortville had the highest mean monthly flow at 241 percent.

Detailed Information on Streamflow

Lake Michigan

The Lake Michigan-Huron water level for January 27, 2017 was one inch above the measurement taken on December 27, 2016, and two inches below the January 27, 2016 water level. Comparison of January monthly mean water levels to long-term (1918-present) average shows Lakes Michigan-Huron water levels were about eight inches above average. On January 31, 2017, the Michigan-Huron water level was 579.02 feet. The water level was 36 inches above the previously lowest recorded monthly mean level for January, set in 2013.

The U.S. Army Corps of Engineers predicts the Lake Michigan-Huron water level to remain the same over the next month. 

Reservoirs

The water levels in all eight Indiana reservoirs being monitored by the U.S. Army Corps of Engineers was above its normal pool elevation on January 31, 2017. The normal pool deviation ranged from 0.1 feet (Brookville) to 15.3 feet (Mississinewa).

Two of the three reservoirs monitored by Citizens Water, Morse and Geist, were above their respective normal pool elevations as of January 31, 2017. Eagle Creek Reservoir was below normal pool elevation. The deviation from normal pools ranged from -1.11 feet (Eagle Creek) to 0.26 feet (Morse).

Ground Water Levels

As of January 31, 2017, recent water level data are available for each of the nine wells being monitored. The mean monthly water levels for the observation wells are above normal for LaPorte 9, Vigo 7, Randolph 3, and Posey 3; near normal for Harrison 8, Morgan 4, Fulton 7, and Clark 20; and below normal for LaGrange 2. 

Real-time data are available for all nine observation wells. The real-time information may be accessed on the following U.S. Geological Survey website: http://waterdata.usgs.gov/in/nwis/current/?type=gw
