Monthly Water Resource Summary

November, 2019

Precipitation

November 2019 Indiana precipitation was generally below normal, with average temperature below normal. The statewide monthly precipitation average was 73.9 percent of normal. The overall monthly temperature average for Indiana was 3.68 degrees Fahrenheit or about 5.5 degrees below normal.

One of Indiana’s nine climate divisions received above normal precipitation for the month of November. Climate Division 1 (NW) received the lowest (43.8) percentage of normal precipitation for the month, while Division 7 (NW) received the highest (109.5) percentage. 

For the year to date, all nine climate divisions have received above to well above normal precipitation, ranging from 107.0 percent of normal for Division 4 (WC) to 134.3 percent of normal for Division 7 (SW).  For the 2020 water year, which began October 1, 2019, total precipitation is normal or above normal for four of the nine climate divisions (81.8 to 133.8 percent of normal). Beginning January 2018, each of the state’s nine climate divisions have received above normal precipitation. These range from 111.4 percent for Division 4 (WC) to 129.7 percent for Division 7 (SW).

The Standardized Precipitation Index (SPI) long-term 12-month index shows Climate Division 7 (SW) in the “extremely wet” category; Climate Division 1 (NW), Climate Division 3 (NE), and Climate Division 8 (SC) in the “very wet” category; Climate Division 5 (C), Climate Division 6 (EC), and Climate Division 9 (SE) in the “moderately wet” category; and the remaining climate divisions in the “near normal” category. The 6-month SPI indices shows Climate Division 7 (SW) in the “moderately wet” category, and the remaining climate divisions in the “near normal” category. The 3-month SPI indices shows Climate Division 1 in the “moderately wet” category, and all remaining climate divisions in the “near normal” category. The 1-month SPI indices shows Climate Division 1 (NW) and Climate Division 2 in the “moderately dry” category, and all remaining climate divisions in the “near normal” category.

U. S. Drought Monitor

For November 26, 2019, the U.S. Drought Monitor shows Indiana is not experiencing any drought conditions. The U.S. Seasonal Drought Outlook predicts no drought conditions through the end of February 2020.

Streamflow

In November 2019, of the twelve streams included in drought reporting since 1999, two had stream flow well above normal, and ten had stream flow well below normal.  The Muscatatuck River near Deputy had the lowest mean monthly flow at 18%, and the Kankakee River at Shelby had the highest mean monthly flow at 159%.   

Detailed Information on Streamflow

Lake Michigan

On November 29, 2019, the Lake Michigan-Huron forecasted water level was two inches below the measurement taken on October 29, 2019, and sixteen inches above the measurement taken on November 29, 2018. On November 30, 2019 the Michigan-Huron level was 581.59 feet, which is about 64 inches above the lowest recorded monthly mean level for November set in 1964. Comparison of November monthly mean water levels to the long-term (1918-present) average shows Lakes Michigan-Huron water level was about 34 inches above the average. All Lake Michigan-Huron data are referenced to the International Great Lakes Datum 1985.

The Lake Michigan-Huron water level is forecast by the U.S. Army Corps of Engineers to fall two inches through December 26, 2019.

Reservoirs

On December 2, 2019, the water levels for all eight reservoirs monitored by the U.S. Army Corps of Engineers were above the normal pool elevation. The deviation from normal pools ranged from 0.1 feet (Brookville) to 5.4 feet (Cagles Mill).  

Two of the three reservoirs monitored by Citizens Energy Group (Morse and Geist) were above their respective normal pool elevations as of December 2, 2019.  The deviation from normal pools ranged from -1.57 feet (Eagle Creek) to 0.30 feet (Morse).

Groundwater Levels

As of December 2, 2019 new water level data is available for all of the nine wells currently monitored. Of the nine wells monitored, data indicates groundwater levels are currently above to well above normal for Lagrange 2, and Vigo 7. Groundwater levels are near normal for Posey 3 and Harrison 8 and below normal for LaPorte 9, Fulton 7, Morgan 4, Randolph 3 and Clark 20.

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
