Title:Modeled daily Yolo Bypass inundation
Alternate Identifier:DOI PLACE HOLDER
Abstract:
Hydrology is one of the major disturbance regimes thought to shape aquatic habitat. However, the San Francisco Estuary (SFE) has been altered by urban and agricultural development. Approximately 95% of the estuary’s wetlands have been diked, channelization is pervasive, and the biological community and water quality have been changed by exotic species introductions, sediment inputs from mining, and pollution from agricultural and urban chemicals. The hydrography has also been altered by upstream dams, which reduce the magnitude of both winter precipitation pulses and spring snow melt pulses when filling reservoirs. In addition to reservoir storage, 35% to 65% of tributary inflow is diverted by large water diversions, as well as thousands of smaller agricultural pumps and siphons. Nevertheless, the SFE retains a substantial area of seasonal off-channel habitat in the Sacramento River, the Yolo Bypass. The Yolo Bypass is hydraulically dynamic and is strongly influenced by tides during low discharge periods and dominated by fluvial river dynamics during flood events. This river floodplain-tidal slough complex is, therefore, much more hydrodynamically variable than the adjacent mainstem Sacramento River channel and benefits from additional metrics than those typically measured for river systems. These data are the modeled duration of inundation in the Yolo Bypass, which was approximated as the number of days in which Yolo Bypass flow was greater than 113.27 m3/s following an inundation event from the Sacramento River (e.g., when the stage height of the Sacramento River exceeded the height of the Fremont Weir, 10.2 meters). Inundation in the Yolo Bypass creates a complex transition zone between the river floodplain and tidal slough habitat, which likely represents the historically dominant habitat in the North Delta. Therefore, inundation brings many advantages for native fish, such as increased growth opportunities on the floodplain, an alternative route into the estuary, and an expansion and diversification of rearing habitat. This definition for inundation duration was developed in Goertler et al. 2017.

Data Entities
Data Table Name:
modeled_inundation
Description:
These data are modeled in the “inundation” R package (10.5281/zenodo.6450271), the primary function, calc_inundation(), calculates the duration of inundation days up to and including that date, and whether there is inundation on any given day in the Yolo Bypass (0 = no, 1 = yes). An inundation event begins when the stage height of the Sacramento River exceeds the height of the Fremont Weir and ends when flow is reduced to within bank of the tidal perennial channel along the Yolo Bypass' eastern edge (e.g., the "Toe Drain”).

Description:The Yolo Bypass is a partially leveed floodplain basin that has been adapted to support flood management in the region. It comprises 24,000 ha of floodplain that is also managed for wildlife and agriculture. The Yolo Bypass was built as a water conveyance system to avoid flooding in the Sacramento metropolitan area, and therefore is meant to drain more quickly than a natural floodplain. Inundation is possible from several sources: (i) the primary input is the Fremont Weir in the north (38.7646608521372, -121.65187661397954), which conveys flood water from the Sacramento River and Feather River, (ii) the Sacramento Weir in the east can also convey flood water from the Sacramento River and American River (38.60547494388854, -121.55813378457187), and (iii) small westside streams, such as Knight’s Landing Ridge Cut, Cache Creek, and Putah Creek (38.51888900052138, -121.69282528578388) flow into the Yolo Bypass. During dry periods, the aquatic habitat in the Yolo Bypass is reduced to a tidal perennial channel along its eastern edge (e.g., the “Toe Drain”, 38.341524061527274, -121.64820729548717). There are also perennial ponds and seasonally managed wetlands on the floodplain (38.67693553499289, -121.64398147843116).

Abstract:Ecological synthesis is a critical component of ecosystem-based management and informed decision-making, both of which are tools for achieving the coequal goals. The need for increased capacity, dedicated time, and coordinated synthesis in the San Francisco Estuary (SFE) is widely recognized and included as an action in the Delta Science Plan, Science Action Agenda, and Interagency Ecological Program Science Strategy. This effort, led by the Delta Science Program (DSP) in partnership with the National Center for Ecological Analysis and Synthesis (NCEAS), provided high-quality training in data science and statistics and an opportunity for enhanced collaboration among agency and academic scientists in a focused working group. This is one of many products from this working group which can be used to offer strong scientific support to inform decision-making for restoration, protection of endangered species, and management of flow actions in the SFE. This definition of inundation duration was developed in Goertler et al. 2017.
