CONCLUSIONS Reaches where salmon must pass numerous dams are less likely to result in viable sub-populations. Management efforts should concentrate on reaches with fewer dams, balancing survival with production potential (amount and quality of available habitat). Where production potentials are equal, reaches with the fewest dams will be more likely to produce self-sustaining populations. To make these balancing decisions managers need estimates of freshwater production potential for all management reaches. They also need better fish passage efficiency and dam mortality estimates that will allow them to 1) improve fish passage, or 2) manage populations in the face of fish passage losses. PRFP Page 140
Appendix C - Penobscot Habitat and Freshwater Juvenile Atlantic Salmon Production Potential Author: Greg Mackey We estimated juvenile Atlantic salmon rearing habitat in the Penobscot basin using both field survey data and data from a GIS-based habitat model (GIS-Based Atlantic Salmon Habitat Model, Draft, 2008, Appendix C, Critical Habitat). Habitat data were aggregated at several spatial scales within the basin, including Dam Reach, Management Reach, and HUC 10. The data used in this work are available as an ARCMap geodatabase. The goals of this work were to 1) provide the best available information on Atlantic salmon rearing habitat in the Penobscot basin, 2) provide an estimate of the relative potential for large parr production in the basin, and 3) Identify reaches with the highest parr production potential. Dam Reaches are defined as areas of the basin that are affected by a common collection of dams; therefore, fish in these reaches experience the same dam-related passage and mortality rates (Figure 1). Management Reaches attempt to organize the basin into reaches that could be managed independently (Figure 2). This provides finer scale information to managers that may be more useful for some management actions. The HUC system can also be used to aggregate data at any HUC level. Management actions may be described by these reaches, but also, finer scale management may be performed at the stream level. In any case, the location of management actions within the geographic hierarchy will be known. Figure 1.
