TFF Water Level Graph 2016

The top graph shows the water level of the Turtle Flambeau Flowage for the prior and current years, Maximum Drawdown and functional Utilization Level on a weekly basis. The lower graph shows the trend of the Flowage Discharge Rate in cubic feet per second for the prior and current years and the mandated minimum discharge rate. Although we were disappointed with the rapid drawdown of the Flowage in July and August, 2015, Xcel energy was in compliance with the terms of the Memorandum of Understanding. The current unseasonably high water level that we are experiencing is due to the above average rainfall received both at the Flowage and across the entire watershed.
