  • Pool 4 2003 does not include backwater isolated or Lake Pepin Stratum.
  • Poolwide analysis was not calculated because no data were collected for the isolated backwater and Lake Pepin strata in 2003, Pool 4.
  • Sampling in Pool 26 and La Grange was only conducted from 1998 to 2004.

Querying for vegetation eveness allows you to see how diverse the pools vegetation species are. It allows you to query based on lifeform and a year range. The diversity index and eveness are calculated using Shannon's diversity index where a value close to 1 means the pool is diverse and a value close to 0 means the pool is not diverse.
