Upshur County Sits on Two Major Drainage Divides

Upshur County straddles a continental drainage divide. Rain that falls on the northern part of the county flows eventually toward the Mississippi River basin. Rain on the southern part flows through the Sabine River system toward the Gulf of Mexico.

This geography matters for water planning, flood risk, and where lakes and creeks are located. Lake O' the Pines sits in the Big Cypress Creek watershed in the county's north. Understanding which watershed your property sits in helps when researching flood maps and water rights.
