Datasets used to asses the effects of antecedent streamflow and sample timing on trend assessments of fish, invertebrate and diatom communities (2002-12) Detecting trends in biological attributes is central to many stream monitoring programs; however, understanding how natural variability in environmental factors affects trend results is not well understood. We evaluated the influence of antecedent streamflow and sample timing (covariates) on trend estimates for fish, invertebrate, and diatom taxa richness and biolgical condition from 2002 to 2012 at 51 sites distributed across the conterminous United States. This data release contains all of the input and output files necessary to reproduce the results presented and discussed in the associated journal article.

This data release consists of invertebrate, water-quality, and covariate data from 1,322 sites and water-quality, covariate, and trend result data from an additional 259 sites with reported water-quality trends but no invertebrate data. Collectively, these data were used to describe invertebrate response to total nitrogen, total phosphorus, or specific conductance and to estimate changes in invertebrate taxa richness in response to changes in water-quality. Description of data processing and analysis are documented in the...
