Real-time models include easily- or continuously-measured factors that do not require that a sample be collected.  Real-time models are presented in two categories: (1) six models with continuous monitor data, and (2) three models with on-site measurements.  Real-time models commonly included variables such as phycocyanin, pH, specific conductance, and streamflow or gage height. Many of the real-time factors were averages over time periods antecedent to the time the microcystin sample was collected, including water-quality data compiled from continuous monitors.  Comprehensive models use a combination of discrete sample-based measurements and real-time factors.  Comprehensive models were useful at some sites with lagged variables (< 2 weeks) for cyanobacterial toxin genes, dissolved nutrients, and (or) N to P ratios.  Comprehensive models are presented in three categories: (1) three models with continuous monitor data and lagged comprehensive variables, (2) five models with no continuous monitor data and lagged comprehensive variables, and (3) one model with continuous monitor data and same-day comprehensive variables.
