11. Using underwater lasers to determine Substrate scale (dot spacing is 7.75 inches)

12. Substrate Classification

13. Sand Small Gravel Cobble Small BoulderLarge BoulderBedrock Some Substrate Types

14. River Surface Characteristics

15. Driftwood River River Characteristics 20 mile 38,503 Sample Points

16. Driftwood River Thalweg Depth 20 mile 38,053 Sample Points

17. Driftwood River Substrate 20 mile 38,053 Sample Points

18. Species at Risk Habitat Maps Rayed Bean (Villosa fabalis) mussel Develop Optimum Habitat Criteria

19. Rayed Bean (Villosa fabalis) Habitat Criteria primarily found in small, shallow rivers usually about 4 feet in depth or less in and near riffles/runs usually found deeply buried in sand and gravel substrates often in and around aquatic vegetation Search (Depth <= 4 feet) River Characteristic = riffle/run Substrate = sand or gravel

20. Rayed Bean (Villosa fabalis) 6.7% Optimum Habitat

21. Obed Wild and Scenic River

23. Virtual tour capabilities

27. Summary - River Habitat Videomapping for Aquatic Species at Risk (SAR) Habitat Cover large reaches (10 miles/day) - continuous Non-intrusive, no access required Determine above and below water features Develop total river habitat suitability index By mapping every foot of the river, the total amount and location of optimum habitat can be determined (development occupancy model) Provides permanent historical video database to evaluate changing habitat conditions

28. Legacy FY 2015 Proposal Species At-Risk, Species of Concern and Declining Species and Habitat (Natural) Pilot or demonstration efforts of new techniques, methodologies, and management practices, including the implementation of new or innovative monitoring and predictive modeling techniques.

31. Snorkel mapping for Species counts Embedded video recorder and GPS on back strap

35. Georeferenced manual underwater recording video for observing under rocks

38. Legacy Project (Year 1) GIS-based streambank mapping to identify areas of erosion potential on rivers/streams within military installations (Camp Atterbury and Fort Benning) Mapping Site-specific Streambank Erosion

39. Streambank Erosion Videomapping Determine erodibility and erosivity Identify areas of restoration needs Cover large areas (10 miles/day) - continuous Non-intrusive, no access required Permanent video database and virtual tour capability Uses EPA Bank Assessment of Non-point source Consequences of Sediment (BANCS) for annual total streambank erosion prediction Used to determine sediment TMDL’s.
