Mill Creek at Big Mill WMA is stocked with catchable rainbow trout during April - October and also maintains a high density of wild brown trout. A floodplain restoration project was completed on the upper 1000 feet of Mill Creek on Big Mill WMA during spring 2014 and an additional 1200 feet in 2019. This project mitigated negative impacts of the incised channel and provided improved shoreline access along the stream in the project area. Access continues to be challenging downstream of the restoration sites and below the mouth of South Fork Mill Creek.(2022)
