U.S. Fish & Wildlife ServiceData are directly from the LAGOS-US platform . The current dataset identifies the lake watershed: the contributing watershed area accumulated upstream to the first connected lake ≥ 10 ha, if present. This definition e mphasizes the importance of local inputs, and also acknowledges the potential for larger upstream lakes to function as sinks. The LAGOS-US dataset contains locational, identifying, and physical information of all lakes ≥ 1 ha and their watersheds in the conterminous U.S. Geospatial files for lakes and watersheds as well as tables for linking across other LAGOS modules and broad-scale lake databases are available. LOCUS data can be linked across LAGOS data products using the unique lake identifier (lagoslakeid).
