The Elm Fork Trinity River is a major tributary of the Trinity River in north central Texas. It originates in Montague County and flows southeast for approximately 85 miles before joining the West Fork Trinity River in Dallas County to form the main stem of the Trinity River. The Elm Fork watershed covers about 2,500 square miles.

Paddling opportunities abound on the Elm Fork, with the most popular section being the 30-mile stretch from Lake Lewisville Dam to California Crossing Dam. This segment offers scenic flatwater paddling suitable for beginners to intermediate paddlers. The river flows clear and cool for the first 8 miles below Lake Lewisville, providing an enjoyable experience through the Trinity River National Water Trail. The overall difficulty is flatwater with occasional swift water sections, particularly near Hebron Parkway. Most paddlers can comfortably navigate the river, though some basic paddling skills are recommended.

The best paddling times are spring through fall, with summer offering warm water but potentially low flows. Notable wildlife includes herons, egrets, and various fish species. The riparian corridor supports diverse plant life, transitioning from post oak savanna to blackland prairie ecosystems.

Key landmarks include the historical site of Bird's Fort near present-day Euless and the gigantic Sam Rayburn Tollway bridge. Popular access points include Lake Lewisville Dam (LLELA) in Lewisville, Trinity River Kayak Co. in Coppell, California Crossing Dam in Dallas, and McInnish Park in Carrollton. The John F. Burke Nature Preserve in Farmers Branch offers a unique 104-acre ecosystem along the river with a potential future paddle drop.

Historically, the Elm Fork was an important transportation route for Native Americans and early settlers. Today, it serves as a vital water source for the Dallas-Fort Worth Metroplex while offering recreational opportunities.

Safety considerations include checking water levels and flow rates, especially after heavy rains. Paddlers should be aware of low-head dams and potential logjams. Multi-day trips are possible by camping at designated sites along the Trinity River Paddle Trail.

The Elm Fork Trinity River provides a surprisingly natural escape within an urban setting, offering paddlers a chance to explore the river's beauty and ecological significance in the heart of the Dallas-Fort Worth area.
