Arlington Heights Park District officials are currently investigating a fish die-off at Lake Arlington. Hundreds of Gizzard Shad came up dead along the shoreline on Sunday at the Lake. The Arlington Heights Park District is in the process of cleaning up the dead fish and District officials have been in contact with DNR about this issue.
The term fish die-off or 'fish-kill', known also as fish die-off and (in Britain) as fish mortality, is a localized die-off of fish populations which may also be associated with more generalized mortality of aquatic life. The most common cause is reduced oxygen in the water, which in turn may be due to factors such as drought, algae bloom, overpopulation, or a sustained increase in water temperature.
The boathouse at Lake Arlington will continue to be open during the cleanup process. Updates will be posted as the investigation continues.
