The following information is from Texas Parks & Wildlife. Navarro Mills Lake provides excellent opportunity for white crappie and catfish. However, turbid water makes angling for largemouth bass and sunfishes difficult. White bass angling is very good at times.
Fishing Cover/Structure: Inundated timber is abundant in the upper end of the lake. However, this shallow water area can be difficult to access during low water periods. Siltation from the watershed has exacerbated this condition. Some vegetation is present in the creeks entering the north side of the lake. Emergent native plant species such as water willow, and smartweed provide a marginal fringe during high water periods. Marine naiad provides some submersed cover near Wolf Creek Park.
Tips & Tactics: Bass anglers should look for patches of pondweed along the north shoreline. Fish these with buzz baits or jig and eel combinations in the spring during the spawn. Catfish and crappie anglers will find live bait works best in the inundated timber in the upper end.
