Using a combination of tabular and spatial data queries, we identified 133,111 flowlines in the National Hydrography Dataset Plus Version 2 (NHDPlusV2) that were created due to breaks in flowlines resulting from flowline intersection with quadrangle map boundaries. We found instances of this occurring in all 18 processing units of the NHDplusV2 dataset. To aid in managing for this characteristic of the NHDPlus, this EcoReach table (nhdplusv2_ecoreachv2.0.csv) assigns all flowlines into units that are representative of ecological stream reaches. These "ecological stream reaches" may be defined by: stream origins, stream confluences, lake or reservoir inflows or outflows, and/or stream outflows (described in more...
