  32. 32. • Reservoir Fish Habitat Partnership formed - 2010 • Nationwide reservoir habitat assessment - 2012 • Habitat management guidelines (BMPs) - 2016 what next?
  33. 33. • improve through feedback system • $$$ - line item • targeted $$$ incentives by geography • nationwide coordination by RFHP • coordination between RFHP and USFWS Fed Aid • application of ARM and SDM tools • improved communication through listserver • establish short-term & long-term goals for 2050
  34. 34. where will we be in 2050? • established line-item funding for reservoir habitat management • matured discipline with its own paradigm (set of problems, concepts, methods, theoretical principles) • reservoir habitat management major at universities • journal of reservoir habitat management
  35. 35. 2050? best way to predict the future is to create it A. Lincoln
