Oregon lakes

FAQ

What official dataset are these lakes from?

Primarily BLM Oregon hydrography waterbody polygons aligned with USGS National Hydrography Dataset (NHD) naming — we keep features typed as Lake or Pond that carry a GNIS name.

Does a mapped lake mean I can swim, boat, or fish there?

Not necessarily. Hydrography confirms the waterbody and its official name/location. Swimming, boating, fishing seasons, and shore access are set by the land or wildlife manager — we do not invent those amenities from the map layer.

Why are many small ponds missing?

We import named Lake/Pond features above a minimum surface-acre threshold so the catalog stays useful for destination discovery. Tiny unnamed or sub-threshold ponds are omitted by design.

What is GNIS on a lake page?

The Geographic Names Information System (GNIS) is the USGS / U.S. Board on Geographic Names database of official feature names and locations. A GNIS name identifies the waterbody; it is not a recreation permit.

How do I know if the shoreline is public?

Ownership and management are not fully encoded in the hydrography polygon. Check the managing agency (Forest Service, BLM, OPRD, county, or private) and any nearby recreation site or trail before you assume shore access.

Do you copy Wikipedia lake facts?

Some Oregon lakes may also be enriched from the Wikipedia “List of lakes of Oregon” and related pages (coordinates, Commons photos, published facts). Treat Wikipedia as secondary; prefer the land manager for access and safety.
