What are they talking about?

Both Lake Wentworth and Crescent Lake are categorized as ‘oligo’ lakes. What the heck does this mean?

First “oligo’ is short for Oligotrophic. If you separate the two parts of this word you have “oligo” which means very little; and “trophic” the root of which is ‘trophy’ meaning nutrients. So an oligotrophic lake is one that has relatively little available nutrients. The nutrients they are primarily referring to are phosphorous and nitrogen.

Scientists classify lake types so they can be easily referred to and their basic characteristics conveyed. In this case scientists are characterizing the fertility of the water body = it’s trophic state.

All lake users and watershed residents (seasonal or year round) need to do their part to keep these lakes in their present oligotrophic states.
