1 Additional Primary Headwater Habitat Stream Parameters

2 Riparian Zone Plant growth between the stream and the floodplains 1 (Riparian in short hand is plants covering stream banks) Plant growth between the stream and the floodplains 1 (Riparian in short hand is plants covering stream banks)

3 Floodplain Quality (left and right bank) Mature Forest, Wetland Immature Forest, Shrub or Old Field Residential, Park, New Field Fenced pasture Conservation Tillage Urban or Industrial Open Pasture, Row Crop Mining or Construction

4 Flow Regime Stream Flowing: Flowing water present at time of assessment. Stream Flowing: Flowing water present at time of assessment. Interstitial Flow with Isolated Pools: Flowing water present in isolated pools, which remain connected by subsurface flows. Dye testing may be needed to document pool connection. Interstitial Flow with Isolated Pools: Flowing water present in isolated pools, which remain connected by subsurface flows. Dye testing may be needed to document pool connection. Moist Channel, Isolated Pools, No Flow: Moist substrate and/or water present in isolated pools, Moist Channel, Isolated Pools, No Flow: Moist substrate and/or water present in isolated pools, but no visual evidence that the water in the pools is flowing. Dry Channel, No Water: A completely dry channel for the entire 200 ft (61 m) stream reach. Dry Channel, No Water: A completely dry channel for the entire 200 ft (61 m) stream reach.

5 Sinuosity 1

6 Stream Gradient

7 Glossary Gradient- Ratio of descent to length of a stream. Gradient- Ratio of descent to length of a stream. Floodplains - Flat land bordering a river and made up of alluvium (sand, silt, and clay) deposited during floods. When a river overflows, the floodplain is covered with water. Floodplains - Flat land bordering a river and made up of alluvium (sand, silt, and clay) deposited during floods. When a river overflows, the floodplain is covered with water. Tributary - A stream that flows to a larger stream or other body of water. Tributary - A stream that flows to a larger stream or other body of water. Sinuosity - A bending or curving shape or movement. Sinuosity - A bending or curving shape or movement. Rise – The drop in elevation of a stream over a given distance (run) Rise – The drop in elevation of a stream over a given distance (run) Run – The length of a stream used to calculate rise. Run – The length of a stream used to calculate rise. Meander - To define the margin of (a body of water) with a meander line. Meander - To define the margin of (a body of water) with a meander line.
