June 2025
Precipitation
June 2025 Indiana precipitation was above normal, with average temperature above normal. The statewide monthly precipitation average was 114.0 percent of normal. The overall monthly temperature average for Indiana was 74.1 degrees Fahrenheit or 3.2 degrees above normal.
Eight of the nine climate divisions received above normal to much above normal precipitation for June (see Percent of Normal Precipitation Table). Climate Division 8 (SC) received the highest (141.2) percentage of normal precipitation for the month, while Climate Division 1 (NW) received the lowest (88.0) percentage.
Precipitation for the year to date (2025) ranges from 83.1% to 134.3% through June. Precipitation for the Water Year 2025 to date ranges from 84.1% to 126.5% through June. Over the 2-year period (from July 2023-June 2025), eight of the nine climate divisions have received below normal to near normal precipitation ranging from 89.4% for Climate Division 4 (WC) to 109.2% for Climate Division 8 (SC).
The 12-month SPI indices show Climate Division 8 (SC) in the “extremely wet” category; climate divisions 7 (SW) and 9 (SE) in the “moderately wet” category; and the remaining climate divisions in the “near normal” category. The 6-month SPI indices show Climate Division 8 (SC) in the “very wet” category; climate divisions 7 (SW) and 9 (SE) in the “moderately wet” category; and the remaining climate divisions in the “near normal” category. The 3-month SPI indices show Climate Division 8 (SC) in the “extremely wet” category; climate divisions 5 (C), 7 (SW), and 9 (SE) in the “very wet” category; Climate Division 6 (EC) in the “moderately wet” category; and the remaining climate divisions in the “near normal” category. The 1-month SPI indices shows climate divisions 5 (C) and 8 (SC) in the “moderately wet” category and all remaining climate divisions in the “near normal” category.

U. S. Drought Monitor
For July 1, 2025, the U.S. Drought Monitor shows the northwestern and north-central parts of the state are experiencing “Abnormally Dry” or” Moderate Drought” conditions. While the rest of the state is not experiencing any drought conditions. The U.S. Seasonal Drought Outlook predicts the current drought conditions to end by the end of September 2025.

Streamflow
In June 2025, three of the streams included in drought reporting since 1999 had below normal to much below normal stream flow. St. Marys River at Decatur had the lowest mean monthly flow at 36%, and the Sugar Creek at Crawfordsville had the highest mean monthly flow at 255%.
Detailed Information on Streamflow
Lake Michigan
On June 27, 2025, the Lake Michigan-Huron forecasted water level was 2 inches above the measurement taken on May 27, 2025, and 10 inches below the measurement taken on June 27, 2024. On June 30, 2025, the Michigan-Huron level was 578.97 feet, which is 28 inches above the lowest recorded monthly mean level for June set in 1964. A comparison of June monthly mean water levels to the long-term (1918-present) average shows Lakes Michigan-Huron water levels were about 6 inches below 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 rise 0 inches over the next month.
Reservoirs
On July 1, 2025, 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
pool ranged from +0.2 feet (CM Hardin) to +12.2 feet (Monroe).
All three reservoirs monitored by Citizens Water, Morse and Geist, and Eagle Creek were above their respective normal pool elevations as of July 1, 2025. The deviation from normal pool ranged from +0.25 feet (Geist) to +0.72 (Eagle Creek).
Table and reservoir graphs are appended.
Groundwater Levels
As of July 1, 2025, new water level data is available for all nine wells currently monitored. Of the nine wells, data indicates that water levels are below normal for LaPorte 9, Fulton 7, and LaGrange 2. Water levels are near normal for Vigo 7, Morgan 4, Randolph 3, Posey 3, Harrison 8, and Clark 20.
Real-time data is available for all of the wells and may be accessed on the U.S. Geological website.
