Overview  Riparian zones: Generally mostly grasses with few wooded low coverage areas. Ex. Martinville  Stream Width: Average between 2m and 4m  Stream Depth: Average Between 20 and 35cm  Embeddedness: Varied between 1.5 to 7cm  Erosion: Banks fairly equal, < .35m. Ex. Martinville  Substrate: Mid-sized particles. Ex. Newell  Flow: Averages < .5m/s. Ex. Crow

Overview  Brow Trout found in Crow, Culvers, Harker, Martinville  Martinville high abundance of fingerlings  Largest trout found in Crow  Brooke Trout found in Harker  Ozark Minnow found only in Newell  Each stream displayed a variety of minnows, chubs, suckers, daces, scuplins, etc.

Survey Summary  All five streams vary from one another.  Found trout of various sizes in Crow, Culvers, Harker, and Martinville.  Habitat, chemistry, invertebrate, and fish studies suggests that Crow, Culvers, Harker, and Martinville are suitable for trout habitat.  No trout found in Newell; Habitat, chemistry, and invertebrate studies are comparable to rest of streams with exception of slower stream flow and large substrate particles. Most transect variation of substrate.
