Recent legal rulings on listed fish populations in the Sacramento-San Joaquin Delta bring public attention to conservation of these species through the water management in the Southern Delta. However, there may be a trade-off between fish conservation in the Delta and agricultural economy in the Central Valley through the operation of Central Valley Project and the State Water Project pumping plants in the southern Delta. Policy-makers should at least know the economic implications of preserving listed species in terms of foregone agricultural returns even before making conservation plans.

520 $a Recent legal rulings on listed fish populations in the Sacramento-San Joaquin Delta bring public attention to conservation of these species through the water management in the Southern Delta. However, there may be a trade-off between fish conservation in the Delta and agricultural economy in the Central Valley through the operation of Central Valley Project and the State Water Project pumping plants in the southern Delta. Policy-makers should at least know the economic implications of preserving listed species in terms of foregone agricultural returns even before making conservation plans.
520 $a This paper aims to examine the economic cost of fish conservation under two different sets of water year assumptions, focusing on the endangered winter-run Chinook salmon. The first set assumes that only water export changes under different water years according to the Department of Water Resources water year classifications and 10% step of pumping reduction scenarios and other environmental factors are fixed at a historical average. The second set assumes that all the environmental factors change over the water years.
520 $a The economic costs of pumping reductions under different scenarios are first calculated using a well-known statewide agricultural production model (SWAP), which applies a positive mathematical programming (PMP) method to the California agricultural production. Increases in the winter run Chinook salmon population under the same scenarios are then estimated through a multi-stage dynamic fish population model. In the estimation of environmental impacts for the stage from juvenile to age 2 adult, three methods are considered: direct estimation by ordinary least squares, a method using prior estimates of environmental impacts from the literature, and estimation of other environmental impacts using a prior estimate of water export impact. The third method proves to be a more precise and reliable method and is used for the point and 95% confidence interval estimates of winter run population increase. By combining the estimates of economic cost from the SWAP with the estimates of population increase from the winter-run population model, the economic costs per age 3/4 adult salmon are estimated for two cases.
520 $a The point estimates of economic costs to increase one age 3/4 adult salmon range from $1,304 to $114,966 for the first case and from $864 to $721,120 for the second case with wide 95% confidence intervals. Economic costs increase at an increasing rate as the pumping cutback increases from 10% to 100% under the first case.
520 $a The point estimate of economic cost for the both cases is ordered from highest to lowest: critical, dry, wet, above normal, and below normal. Although the economic cost estimates are upper bounds of true economic costs due to limitations of biological data, the qualitative results provide policy-makers with economic data that can be used to help understand the tradeoffs in water management for the Southern Delta. One important factor in determining the agricultural losses is the different water years and the corresponding dependency of the farms on water exports.
