A) Crosses Red River into Grayson County

B) Crosses tributaries that feed Lake Lavon in Collin County

C) Passes East Lake Ray Hubbard in Rockwall County near Royce City

D) Travels west of Cedar Creek Reservoir in Kaufman County

E) Passes under the Trinity River at the Henderson-Navarro County line

F) Crosses under both segments of Richland Chambers Reservoir in Navarro Count. [According to Enterprise employees speaking at a community meeting in Corsicana, June 26, 2013, the segment under Richland Chambers will be shut down and rerouted along a new Seaway Loop right of way when the planned Seaway Loop is built in 2013-14; after that, the two Seaway pipelines will cross tributaries that feed Richland Chambers, but will no longer cross the lake itself.]

G) Crosses over the Carrizo-Wilcox aquifer where it outcrops in Freestone and Leon Counties, and then along the Brazos River in Madison, Grimes, Waller, and Fort Bend Counties.
