Know What Your Project Requires

Almost every private parcel in the county shares at least one boundary with federal land. Federal boundary surveys require coordination with the relevant federal land management agency and the use of BLM cadastral survey records for the Public Land Survey System corners.

Klamath River and Tribal Land Complexity

Recent Klamath River dam removal projects have altered the river corridor significantly. Properties along the Klamath in Siskiyou County may involve tribal land adjacency, federal reserved water rights, and rapidly changing river morphology that affects thalweg (centerline) boundary determinations.
