Arguments

year

The year of simulation

adults

Potential spawning adults for each watershed (length = 31) values must be integer

hatch_adults

Total hatchery adults

mode

A value meant to be inherited to determine if model is in "seed", "calibrate", or "simulate" mode

month_return_proportions

The proportion of fish returning for each month

prop_flow_natal

A dataset containing the proportion flows at tributary junction coming from natal watershed using October CALSIM II flows. These proportions are used to estimate straying in the CVPIA SIT Salmon Population Model. More details at proportion_flow_natal

south_delta_routed_watersheds

Indicator of whether fish have access to a region. More details at south_delta_routed_watersheds

gates_overtopped

A monthly TRUE or FALSE value to describe if the gates are overtopped to the bypasses (years 1980-2000) for use with the CVPIA SIT Salmon Population Model to apportion fish onto the bypasses. More details at gates_overtopped

tisdale_bypass_watershed

Indicator of whether fish have access to a region. More details at tisdale_bypass_watershed

yolo_bypass_watershed

Indicator of whether fish have access to a region, More details at yolo_bypass_watershed

migratory_temperature_proportion_over_20

The median proportion of days over 20°C per month. More details at migratory_temperature_proportion_over_20
