Little Wapsipinicon River N of Sumner (REMAP #248)

Invert Sampling Series #2287

A sampling series is a set of benthic macroinvetebrate sessions that are used to generate an Index of Biotic Integrity (IBI). A standard series will contain 3 quantitative sessions and one qualitative session. However, sometimes quantitative replicates are lost in the field, buried, or otherwise damaged enough not to be included in a series. There may even be an extra replicate collected and included in the series. This is rare and typically only occurred during the early stages of the biological assessment program.

Comments

Artificial substrates were in lower than desirable velocity, though is was the highest velocity in the reach. Velocities were good through most of the deployment, with impoundment by a beaver dam occurring only in recent day (after July 19). The bottom plates of the substrates had been buried until checked on July 19.
