Trout Creek Trout Creek is an 8-mile hard water stream that is a tributary to Duck Creek.
Trout Creek is classified as a warm water sport fishery.
The lower and mainstem reach have relatively steep topography, are well buffered by woodlands and have few nonpoint source impacts. The headwaters originate in areas with more gentle topography, poor buffering and significant nonpoint source impacts. Water chemistry results from the spring of 1995 depicted very high amounts of suspended solids.
