Summary of Fathead Minnow survival (in percent) from water samples collected from the Grassland Bypass Project's monitoring site between 2001 and 2009.  Statistically significant reduced responses (P<0.05) are indicated with an asterisk.  Statistics were computed between all site means and the Delta Mendota Canal (DMC) ambient water sample.  No statistics were computed between sampling dates.  Results are for seven day tests.  (Key at bottom of table.)
