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.
