Dead fish at pond no cause for concern
A couple dozen dead fish surfaced at the Marshall Habilitation Center Lake last week, and it turns out that it might be more common than some realize.
A low amount of oxygen in the water is most likely the cause of fish dying last week. Missouri Department of Conservation Agent Chase Wright said that could happen for multiple reasons.
Thick ice in the wintertime or too much algae, which has recently been the case, can block sunlight from filtering into the lake. The website www.lakeaccess.org describes a process in which low oxygen at the bottom of a lake combined with summer heat can be problematic.
Mid-summer, when strong thermal stratification develops in a lake, may be a very hard time for fish. Water near the surface of the lake is too warm for them, while the water near the bottom has too little oxygen. Conditions may become especially serious during a spate of hot, calm weather, resulting in the loss of many fish. You may have heard about summertime fish kills in local lakes that likely results from this problem, the site reads.
Anglers are still encouraged to fish the lake. Currently, Wright believes there is no cause for concern regarding public health and safety.
