How big do inland rainbows get approximately? Do inland rainbows generally get bigger than inland browns? Thank you!

Hi Angler, most rainbows and brown trout stocked in small lakes will grow to about 5-6 lb..  Some can reach weights of 10 lb. Their grown rate will depend on how plentiful their food supply is and whether or not they have been “engineered”. In western Canada natural strains of in-land rainbows as those in Quenell Lake, Kootenay Lake, Lake Pend Orielle, Naknek Lake and Lake Illiamna, BC can reach weights of over 20 lb. Both Rainbow and Brown trout have been genetically altered to grow over 30 lb. in size.
