aquatics overview
Students gather at the lake's edge to drag the shallow water with their collecting nets under the watchful eye of their Blinn College volunteer instructor.

Macroinvertebrates are the small bugs living in the shallow water at the lake's edge. Different types of bugs have different abilities to tolerate polluted water which makes them good indicators of how polluted the water is.

Sometimes you get a lot, sometimes not so many. Everyone wants to see what's new in the net.

Once the macroinvertebrates are collected, it's the students job to identify and count them quickly so they can be returned to the lake in healthy condition.
