Chapter 12: Reservoirs

Section 1: Introduction

This chapter deals primarily with large reservoirs, the entities responsible for the reservoirs, and their impact on highway facilities and vice versa. TxDOT storm water detention is covered in Chapter 10.
Many TxDOT highways and roadways are located either alongside of a reservoir, cross upstream of a reservoir, or cross downstream of a reservoir. Reservoirs can impact highways by affecting the following:
  • the natural storm runoff
  • the highway alignment and/or location
  • the risk of highway overtopping
  • the embankment stability
