November, 2014

Precipitation

November 2014 Indiana precipitation was generally below normal across most of the state, with temperature on the whole also below normal. The statewide monthly precipitation average was about 80 percent of normal. The overall monthly temperature average for Indiana was 35.9 degrees Fahrenheit or 6.4 degrees below normal.

One of Indiana’s nine climate divisions received above normal precipitation for the month of November. The north-central climate division received the highest (102.9) percentage of normal precipitation for the month, while the southeastern division received the lowest (59.3) percentage.

For the year to date, each of the nine climate divisions have received above normal precipitation, ranging from 102.9 percent for the southeastern climate division to 125.2 percent for the northwestern division. For the 2015 water year, which began October 1, 2014, total precipitation is above normal for seven of the nine climate divisions (90.7 to 130.4%). Starting from January 2013, each of the state’s climate divisions has received above normal precipitation. Those ranges are from 105.3 percent for the southeastern division to 116.5 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 division is in the “very wet” range, and the east-central division lies in the “moderately wet” category. The 6-month index shows the northwestern climate division in the “very wet” range. The rest of the state is in the “near normal” category. For the 3-month index, the entire state is in the “near normal” range. Likewise for the 1-month index, all nine of the state’s climate divisions lie within the “near normal” category.

U. S. Drought Monitor
The period ending November 25, 2014 showed no drought conditions for Indiana.

Streamflow
Mean monthly flows for seven of the 12 monitored streams were below their historical mean monthly flow for the month of November. The Muscatatuck River near Deputy had the lowest mean monthly flow with 54 percent of the historical mean flow for the month. The Eel River at North Manchester had the highest mean monthly flow with 169 percent of the historical mean flow for the month.

Detailed Information on Streamflow

Lake Michigan

The lake Michigan-Huron water level for November was one inch below last month’s water level, and 21 inches above the November 2013 water level. Comparison of November monthly mean water levels to long-term (1918-present) averages shows that Michigan-Huron water levels were about six inches above average. On November 30, 2014, the Michigan-Huron water level was 579.23 feet. The water level was about 35 inches above the previously lowest recorded monthly mean level for November, set in 1964.

The U.S. Army Corps of Engineers predicts the lake Michigan-Huron water level to decrease two inches over the next month.

Reservoirs

The water levels in seven of the eight Indiana reservoirs being monitored by the U.S. Army Corps of Engineers were above their normal pool elevation on November 30. The normal pool deviation ranged from -0.1 feet (Brookville) to 9.0 feet (Salamonie).

One of the three reservoirs monitored by Citizens Water-Morse, Geist, and Eagle Creek- was below its normal pool elevation as of December 1, 2014. The reservoirs’ deviation from their normal pools ranged from -0.65 feet (Eagle Creek) to 0.30 feet (Morse).

Ground Water Levels
As of November 30, 2014, recent water level data are available for each of the nine wells being monitored. The water level for the observation wells is above normal for LaPorte 9, Fulton 7, Vigo 7, and Harrison 8; near normal for Randolph 3, Posey 3, and Clark 20; and below normal for Morgan 4 and LaGrange 2. Groundwater levels are expected to increase through December 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
