... , including but not limited to alternatives considered but not adopted by FWS (e.g., potential entrainment index and the delta smelt behavioral model) and NMFS (e.g., bubble-curtain technology and engineering solutions to reduce diversion of emigrating juvenile salmonids to the interior and southern Delta instead of towards the sea)

... • Are there provisions in the FWS and NMFS biological opinions to re solve potential incompatibilities between the opinions with regard to actions that would benefit one listed species while causing negative impacts on another, including, but not limited to, prescriptions that: (1) provide spring flows in the Delta in dry years primarily to meet water quality and outflow objectives pursuant to Water Board Decision-1641 and conserve upstream storage for summertime cold water pool man agement for anadromous fish species; and (2)

... To the extent that wa ter flows through the Delta system contribute to ecosystem structure and functioning, explore flow options that would contribute to sustain ing and restoring desired, attainable ecosystem attributes, while provid ing for urban, industrial, and agricultural uses of tributary, mainstem, and Delta waters, including for drinking water. • Identify gaps in available scientific information and uncertainties that constrain an ability to identify the factors described above.
