Page 17, paragraph 1: The last sentence originally read:
Analyses of effects of outflow (or X2) together with export flow (not export:inflow ratio) have revealed nonexistent (salinity; Kimmerer unpublished) or very weak (striped bass survival, Kimmerer et al. 2001) effects of export flow.
The last sentence should be replaced with the following to clarify that salinity in the Delta can be affected by export flow:
Analyses of effects of outflow (or X2) together with export flow (not export:inflow ratio) have revealed nonexistent (salinity in Suisun Bay; Kimmerer unpublished) or very weak (striped bass survival, Kimmerer et al. 2001) effects of export flow.
Page 48, paragraph 1: The last sentence originally read:
Blooms of Microcystis have occurred in the southern Delta (Lehman and Waller 2003).
The last sentence should be revised as follows to state that Microcystis blooms throughout the Delta.
Blooms of Microcystis have occurred throughout the Delta (Lehman and Waller 2003).
Page 63, paragraph 1: The first three sentences of the paragraph originally read:
The principal exception to the generally saturated oxygen concentrations occurs in late summer to early fall in the San Joaquin River near Stockton (Hayes and Lee 1998, 1999, 2000; Lehman et al. 2004), a region not included in Figure 32. In that region, a combination of high summer temperature and high organic matter loading and phytoplankton production result in high oxygen demand relative to gas exchange with the atmosphere. Furthermore, stratification presumably limits oxygen transport to the bottom, and together with planktonic and benthic oxygen consumption results in low oxygen concentration (less than ~5 mg L-1) near the bottom. This may impede movement of fish through the area (Hayes and Lee 1998, 1999, 2000), although estuarine organisms may tolerate lower values (e.g., Stalder and Marcus 1997).
The principal exception to the generally saturated oxygen concentrations occurs in late summer to early fall in the San Joaquin River near Stockton (Hayes and Lee 1998, 1999, 2000, Lehman et al. 2004), a region not included in Figure 32. High oxygen demand relative to gas exchange with the atmosphere in that region was previously attributed to high summer temperature and high organic matter loading and phytoplankton production, but Lehman et al. (2004) presented results showing that loading of nitrogenous nutrients from sewage treatment plants could account for most of the biological oxygen demand. Low dissolved oxygen may impede movement of fish through the area (Hayes and Lee 1998, 1999, 2000), although estuarine organisms may tolerate lower values (e.g., Stalder and Marcus 1997).
