Understanding Plant Lake Levels*

The Lake Levels (Elevation in feet Local Datum) represent the level of the lakes at the hydros.

Norway/Lake Shafer FERC Operating Target
645.15 ft (Normal)
644.90 ft - 645.90 (Low-High)

Oakdale/Lake Freeman FERC Operating Target
610.35 ft (Normal)
610.10 ft - 611.10 (Low-High)

Understanding Plant Discharge Levels

The Plant Discharge (cubic feet per second) represents the water flow through each plant.

As conditions warrant
Flood Emergency
13,000 Cubic Feet/Second
Flood Warning
9,000 Cubic Feet/Second
Flood Watch
<=300 Cubic Feet/Second**

* Change in elevation taken near the face of the hydros does not reflect or equate to the same potential change in depth for other areas of the lake. A change of .01 ft in the surface elevation equates to 1/100th of a foot or .12 inches. NIPSCO does not measure average depths.

** An Abnormally Low Flow (ALF) event occurs at the Oakdale Dam when the prior 24 hour daily average for flows at Winamac USGS gauge drop below 300cfs. During an ALF event NIPSCO is required to maintain 1.9 times the previous 24 hour daily average flow measured at the USGS gauge in accordance with the USFWS mandate, which could result in lower lake levels. An ALF event will end once the 24 hour average rises above 300 cfs at the Winamac USGS gauge and hourly readings at the Oakdale USGS gauge are above 500 cfs. (This is based on USGS data).

About NIPSCO's Hydro Electric Plants

Northern Indiana Public Service Company (NIPSCO) owns and operates two Hydro Electric Plants in northern Indiana. Norway Hydro Electric Plant was put in service in 1923 and NIPSCO purchased the plant in 1944. Norway Hydro maximum output is 7.2 mw. Oakdale Hydro Electric Plant was put in service in 1925 and NIPSCO purchased the plant in 1944. Oakdale Hydro maximum output is 9.2 mw. Norway and Oakdale were licensed by FERC on October 2, 2007. NIPSCO operates these facilities as Run-Of-River dams. In other words, flow through the dams is matched as close as possible to the flow coming into the dams. These facilities are not flood control dams.
