June, 2015

Precipitation

June 2015 Indiana precipitation was generally well above normal across most of the state. Temperature on the whole was normal. The statewide monthly precipitation average was about 213 percent of normal. The overall monthly temperature average for Indiana was 70.9 degrees Fahrenheit, which is the normal average temperature for June.

Each of Indiana’s nine climate divisions received above normal precipitation for the month of June. The northeastern climate division received the highest (270.0) percentage of normal precipitation for the month, while the southeastern division received the lowest (171.9) percentage.

For the year-to-date, each of the nine climate divisions have received above normal precipitation, ranging from 107.9 percent for the west-central climate division to 129.5 percent for the southwestern division. For the 2015 water year, which began October 1, 2014, total precipitation is above normal for each of the nine climate divisions (103.4 to 120.9%). Starting from January 2014, five of the state’s climate divisions have received above normal precipitation. Those ranges are from 96.7 percent for the southeastern division to 115.6 percent for the northwestern division.

For the Standardized Precipitation Index (SPI) long-term 12-month index, seven of Indiana’s nine climate divisions are in the “near normal” category. The northwestern and southwestern  divisions are in the “moderately wet” range. The 6-month index shows the north-central, west-central, and central climate divisions in the “near normal” category. The rest of the divisions are in the “moderately wet” range. For the 3-month index, the northeastern climate division is in the “extremely wet” category, and the west-central division is in the moderately wet” range. The remaining divisions are in the “very wet” category. The 1-month index shows the west-central, east-central, south-central, and southeastern climate divisions in the “very wet” category. The rest of the state lies in the “extremely wet” range.

U. S. Drought Monitor

The period ending June 30, 2015 showed no drought conditions for Indiana.

Streamflow

Mean monthly flows for each of the 12 monitored streams were above or well above their historical mean monthly flow for the month of June. The East Fork White River at Shoals had the lowest mean monthly flow with 147 percent of the historical mean flow for the month. The St. Marys River at Decatur had the highest mean monthly flow with 900 percent of the historical mean flow for the month.

Detailed Information on Streamflow

Lake Michigan

The lake Michigan-Huron water level for June was six inches above last month’s water level, and 13 inches above the June 2014 water level. Comparison of June monthly mean water levels to long-term (1918-present) averages shows that Michigan-Huron water levels were about eight inches above average. On June 30, 2015, the Michigan-Huron water level was 579.79 feet. The water level was about 39 inches above the previously lowest recorded monthly mean level for June, set in 1964.

The U.S. Army Corps of Engineers predicts the lake Michigan-Huron water level to increase one inch over the next month.

Reservoirs

The water level in each of the eight Indiana reservoirs being monitored by the U.S. Army Corps of Engineers was above or well above its normal pool elevation on June 30, 2015. The normal pool deviation ranged from 2.4 feet (Brookville) to 50.2 feet (J.E. Roush).

Each of the three reservoirs monitored by Citizens Water-Morse, Geist, and Eagle Creek- was above its normal pool elevation as of June 29, 2015. The reservoirs’ deviation from their normal pools ranged from 1.22 feet (Eagle Creek) to 1.26 feet (Geist).

Ground Water Levels

As of June 30, 2015, recent water level data are available for each of the nine wells being monitored. The water level for the observation wells is below normal for LaGrange 2; and near or above normal for LaPorte 9, Fulton 7, Vigo 7, Morgan 4, Randolph 3, Posey 3, Harrison 8, and Clark 20. Groundwater levels are expected to decrease through July for much of the state.

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
