What defines the boundary line along rivers in Texas?

The boundary line along rivers in Texas is defined by the midway mark between the lower "accretion" bank and the toe of that bank. This definition stems from the principles of riparian rights and the way property boundaries are established in relation to moving bodies of water.

In Texas, when a river flows through property, the landowner's rights extend to the center of the river, but this can be influenced by the nature of the riverbanks and whether the water body is navigable or not. The "lower accretion bank" refers to the channel side that is closest to the path of the river, while the "toe of the bank" is the lower part of the riverbank. The midpoint between these two points is recognized for determining property boundaries due to the dynamic nature of rivers, which can change course over time, affecting the extent of land owned.

Understanding this concept is vital for surveyors and landowners alike to ensure clarity in property rights and land use along riverbanks.
