Lake Water Levels

The above chart provides a weekly 'snapshot' of water levels on Mississippi Lake.


During periods of rapid change in water levels (spring runoff or severe storms) the chart may be updated at more frequent intervals. Throughout most of the year, the levels should track within the target range (black lines). During the spring runoff, there is no target range due to the variability in timing of spring melt and ice conditions.  Through most of the summer we would expect to see a gradual decline in levels (within the target range).

Historical Data:  the above data is available in tabular and chart format for the years:

2016, 2017, and 2018

2019, 2020, and 2021

2020, 2021, and 2022

2022 and 2023

The Mississippi Lake water level chart is produced by MLA, using information gathered by the Mississippi Valley Conservation Authority (MVCA).  Here are direct links to the MVCA website for additional information regarding the entire Mississippi River Watershed:


FLOOD WARNING information.  It is important to note that severe storms, with subsequent heavy rainfall, may result in fairly rapid increases in water levels.  Consult the MVCA for detailed information and guidance regarding flooding conditions;

Water Levels elsewhere in the Watershed. MVCA tracks lake levels and stream flow throughout the watershed.
