Quite variable in size, mature rainbow trout may weigh one or two pounds in streams and more than 15 pounds in the Great Lakes. Whether the fish is small or large, fishing for rainbow trout is a popular pastime for many New York anglers.ake trout are long-lived, with some adults reaching more than 20 years old in certain waters. These older fish can reach large sizes. Great Lake's lake trout often reach weights of 15 pounds or more. The current New York State record lake trout weighed more than 39 pounds.
The pH of pure water (H20) is 7 at 25oC, but when exposed to the carbon dioxide in the atmosphere this equilibrium results in a pH of approximately 5.2. Because of the association of pH with atmospheric gasses and temperature, it is strongly recommended that the water be tested as soon as possible.
When I water them, I always add some vinegar to the water because they definitely have no tolerance for high pH, and high means even 6.0, a pH level usually considered safely acidic. If you add a tablespoon or two of vinegar per gallon of tap water, it should be ok, given the nature of NM tap water.
