A genus is composed of a number of similar SPECIES.
Most organisms can tolerate a very narrow pH range close to neutral, i.e., around pH 7. It is likely that there would not be much life in the lake at pH 3.

Once the pH rises to above around 9, the solution is starting to become basic, and once again, few organisms will survive.
