Title	Yolo Bypass Salmonid Habitat Restoration and Fish Passage: Scenario Analysis of Fremont Weir Notch - Integration of Engineering Designs, Telemetry, and Flow Fields
Lead	U.S. Army Corps of Engineers [USACE]
Description	This study analyzes 12 notch scenarios in the Fremont Weir in terms of entrainment of juvenile salmon. The goal is to quantify the relative entrainment rates (between 0 and 1) across the suite of scenarios and to identify possible strategies for enhancing entrainment outcomes. This study does not predict future entrainment as models generally do not predict future outcomes so much as highlight trends
Science topics	Chinook Salmon, Endangered species, Water conveyance and infrastructure

Title	Waterborne Commerce of the United States [WCUS] Monitoring
Lead	U.S. Army Corps of Engineers [USACE]
Description	Waterborne Commerce of the United States (WCUS) is a series of publications which provide statistics on the foreign and domestic waterborne commerce moved on the United States waters. The Manuscript Cargo and Trips File (Parts 1-4) presents data on the movements of commodities at the ports and harbors and on the waterways and canals of the United States and its territories. National totals by traffic and commodity are provided under waterway codes 9950. Data on foreign commerce are supplied to the Corps of Engineers by the Bureau of Census. Data for the compilation of the domestic statistics are collected by the Corps of Engineers, Department of the Army.
Science topics	Docks and ports, Vessels and shipping channels

Title	Levee Waterside Erosion Surveys
Lead	U.S. Army Corps of Engineers [USACE]
Description	The USACE, with DWR sponsorship, has contracted for waterside erosion surveys of the Sacramento River system since 1998. As stated earlier, FPIIB began conducting waterside erosion surveys of the San Joaquin River portion of the State-Federal flood protection system Project levees in September of 2006. The primary purpose of these surveys is to: a) inspect the waterside levees for erosion activity, b) document and report new erosion sites, c) document and report the current condition of previously identified erosion sites, and d) rank and rate the severity of erosion sites based upon the findings from the field survey. The USACE and its contractors generate the report on erosion found in the Sacramento River system;FPIIB staff supplements their inspection reports with the USACE data as it becomes available.

Title	Sacramento District Water Control Data System [WCDS]
Lead	U.S. Army Corps of Engineers [USACE]
Description	The Sacramento District's Water Control Data System (WCDS) collects data necessary for the management of Corps Reservoirs and Flood Control Space in Non-Corps Reservoirs (i.e.,"Section 7" projects)
Science topics	Water operations and exports, Water storage, Water conveyance and infrastructure, Wastewater discharge, Surface water flow, Stage, Flood, Air temperature, Precipitation, Wind, Main channels, Sloughs, Environmental drivers, Snowpack and snow water equivalent SWE, Water use and demand
