Monthly Water Resource Summary

October, 2022

Precipitation

October 2022 Indiana precipitation was below normal, with average temperature slightly below normal. The statewide monthly precipitation average was 54.3 percent of normal. The overall monthly temperature average for Indiana was 53.1 degrees Fahrenheit or 0.9 degrees below normal.

All nine climate divisions received below normal to much below normal precipitation for October (see Percent of Normal Precipitation Table).  Climate Division 6 (EC) received the lowest (24.7) percentage of normal precipitation for the month, while Climate Division 1 (NW) received the highest (97.9) percentage.

For the year to date, three of the nine climate divisions have received near to above normal precipitation, ranging from 87.1 percent of normal for Division 5 (C) to 110.2 percent of normal for Division 7 (SW). Over the longer duration (from January 2021) all nine climate divisions have received near normal to slightly above normal precipitation ranging from 94.4% for Climate Division 6 (EC) to 106.3% for Climate Division 3 (NE).

The 12-month SPI indices shows all climate divisions in the “near normal” category.  The 6-month SPI indices shows all climate divisions in the “near normal” category. The 3-month SPI indices shows Climate Division 6 (EC) in the “moderately dry” category; with the remaining climate divisions in the “near normal” category. The 1-month SPI indices shows Climate Division 6 (EC) in the “severely dry” category, climate divisions 8 (SC) and 9 (SE) in the “moderately dry” category; with the remaining climate divisions in the “near normal” category.

Explanation of Standard Precipitation Index (SPI)

U. S. Drought Monitor

For September 27, 2022, the U.S. Drought Monitor shows most of northern Indiana is experiencing “abnormally dry” conditions. The U.S. Seasonal Drought Outlook predicts current drought conditions in Indiana to end by the end of December 2022.

Streamflow

In October 2022, all the twelve streams included in drought reporting since 1999 had much below normal stream flow.  Muscatatuck River near Deputy had the lowest mean monthly flow at 6%, and the Kankakee River at Shelby had the highest mean monthly flow at 59%.

Detailed Information on Streamflow

Lake Michigan

On October 28, 2022, the Lake Michigan-Huron forecasted water level was four inches below the measurement taken on September 28, 2022, and 13 inches below the measurement taken on October 28, 2021. On October 31, 2022, the Michigan-Huron level was 579.33 feet, which is 35 inches above the lowest recorded monthly mean level for October set in 1964. Comparison of October monthly mean water levels to the long-term (1918-present) average shows Lakes Michigan-Huron water levels were approximately 6 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 over the next month.

Reservoirs

On October 31, 2022, the water levels for seven of the eight reservoirs monitored by the U.S. Army Corps of Engineers were below the normal pool elevation. The deviation from normal pool ranged from -6.22 feet (Roush) to +0.4 feet (Cagles Mill).

All three reservoirs monitored by Citizens Water, Geist, were below their respective normal pool elevations as of October 31, 2022. The deviation from normal pools ranged from -1.47 feet (Eagle Creek) to -0.9 feet (Geist and Morse).

Groundwater Levels

As of November 1, 2022, new water level data is available for all nine wells currently monitored. Of the nine wells monitored, data indicates the groundwater level is currently above normal for Lagrange 2. The groundwater level is near normal for Vigo 7. Groundwater levels are below to well below normal for LaPorte 9, Fulton 7, Morgan 4, Randolph 3, Posey 3, Harrison 8 and Clark 20.  Laporte 9 reached a record low on October 26, 2022, at -8.79 feet.

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:
