The Columbia River forecast provides a six-day prediction of the Columbia River’s navigation channel depth based on weather forecasts and tide tables. The results of the forecast can be impacted by actual weather conditions. This online planning tool incorporates the estimated vessel speed for calculating the estimated arrival time. River forecast data and tide levels are used to estimate the depth at various gauge points along the river.

When planning river transit, ship squat must be taken into consideration. This planning tool is not recommended for actual river navigation and is only intended to give an estimate of future channel conditions.
