Dear Truth Finders,

Last week, one of your classmates asked a seemingly simple question: is Blue Mesa the biggest lake in Colorado? But, like everything, the answer is a bit more complicated. And like the best questions, it leads to a rich conversation rather than a simple answer.

It’s a reservoir not a lake. There’s a larger reservoir in Colorado that also stretches into New Mexico. And the levels of all reservoirs go up and down because they are fed by rivers, which are fed by snowfall.

So we’re dealing with tricky things that all interact and make a giant mess–human-created dams, weather, human-drawn borders.

Sincerely,

Mr. Heimbuck
