Summary

Mainstem rivers are the backbone of a connected network of hydrologic units that cover the landscape. A mainstem connects a headwater source area to an outlet. This data release identifies the same mainstem paths in hydrographic datasets for the conterminous US. The Mainstems dataset includes cross walks between mainstem identifiers and several hydrographic datasets. These cross walk tables do not include geometry. It also includes a summary of all mainstems with headwater and outlet identifiers from other datasets for those mainstems that could be matched. The summary table has highly simplified geometry and should be used for visualization purposes only. Any analysis should rely on source dataset geometry. As a convenience, a geodatabase [...]

Purpose

Persistent, cross-scale, identification of hydrologic features, network navigation, and hydrologic indexing (hydrographic addressing). The cross walk tables in the dataset relate the RF1, NHDPlusV1, NHDPlusV2, Watershed Boundary Dataset snapshot from NHDPlusV2, and Watershed Boundary Dataset from June 2021.
