These can be caused by poor water quality, overfeeding and overstocking. Texas rustlers brought lawlessness, poor management resulted in overstocking, and carelessness introduced destructive diseases. Droughts and overstocking can also result in inland fish kills. Inexperienced ranchers brought poor management, resulting in overstocking, and introduced destructive diseases. Overstocking of fish (or an unusually large spawn) can also result in inland fish kills. The financial burden of this overstocking would lead to its ultimate demise.
