Pages Branch Watershed<br />
The Pages Branch Watershed is located in north-central Davidson County. Pages Branch<br />
originates at an elevation of approximately 680 feet and flows in a southwesterly direction to<br />
an elevation of approximately 374 feet at its mouth. The watershed drains an area of 3.23<br />
square miles and empties into the Cumberland River at river mile 188.5. The watershed is<br />
divided into 4 sub-basins: Upper, Dickerson, Middle, and Lower. Two major tributaries<br />
empty into Pages Branch Mainstem. The watershed is characterized by flat to gently rolling<br />
plains with scattered, steep-sided hills reaching elevations up to 810 feet. Floodplain areas<br />
throughout the watershed are typically narrow and steep except in the lower reaches of the<br />
mainstem where they are flat.<br />
Damage Reaches<br />
Five damage reaches have been identified on Pages Branch and its tributaries (Appendix C,<br />
Figure C.10). Flooding problems in these areas are primarily due to development and<br />
construction in the natural floodplain. Damage Reach 1 is located on the mainstem of Pages<br />
Branch and extends from a point 27 feet above Old Trinity Lane at river mile 1.03 to a point<br />
497 feet above Old Trinity Lane at river mile 1.12. Damage Reach 2 is located on the<br />
mainstem of Pages Branch and extends from a point 12 feet above Dickerson Pike at river<br />
mile 1.46 to a point 223 feet above Donald Street at river mile 1.87. Damage Reach 3 is<br />
located on the Upper Unnamed Tributary of Pages Branch and extends from a point 210 feet<br />
below Donald Street at river mile 0.09 to a point 590 feet below Dellway Avenue at river mile<br />
0.33. Damage Reach 4 is located on the Upper Unnamed Tributary of Pages Branch and<br />
extends from a point 216 feet below Dellway Avenue at river mile 0.41 to a point 593 feet<br />
above Brunswick Drive at river mile 0.78. Damage Reach 5 is located on the Upper<br />
Unnamed Tributary of Pages Branch and extends from a point 391 feet below Jones Avenue<br />
at river mile 0.88 to a point 499 feet above Jones Avenue at river mile 1.02. Table 4-13<br />
provides specific damage information for each reach<br />
