Since the founding of Dallas, many of the city's leaders have dreamed of navigation on the upper Trinity River, but none of their attempts achieved lasting success. Fluctuating water levels and massive snags in the river below Dallas hindered early navigation. In 1866 the Trinity River Slack Water Navigation Co. proposed dams and locks for the waterway. Capt. James H. McGarvey and Confederate hero Dick Dowling piloted "Job Boat No. 1" from Galveston to Dallas, but the trip took over a year. In 1868 the Dallas-built "Sallie Haynes" began to carry cargo southward. Rising railroad freight charges spurred new interest in river shipping in the 1890s. The Trinity River Navigation Co., formed in 1892, operated "Snag Puller Dallas" and the "H. A. Harvey, Jr.," which carried 150 passengers. The "Harvey" made daily runs to McCommas Bluff, 13 miles downstream from Dallas, where a dam, dance pavilion, and picnic grounds created a popular recreation spot. In 1900 - 1915 the U. S. Government spent $2 million on river improvements, including a series of dams and locks, before World War I halted work. A critical 1921 Corps of Engineers report ended further federal investment. Despite sporadic interest in later years, the dream of Dallas an an inland port remains unrealized.
