Natural resource managers invest a considerable amount of resources on surveillance monitoring programs to track the distribution and abundance of species. Although these data can be useful when evaluating spatial and temporal trends for populations, using these data directly assumes the population dynamics signal is greater than the noise in the data that stems from the sampling process. This assumption is frequently unmet. An equally important consideration is the integration of monitoring and natural resource decision-making. Here we are evaluating the adequacy of long term monitoring data from San Francisco Bay-Delta to depict the status of fish populations and developing alternative estimators that can be integrated with water resource decision-making.
