These points represent the 124 hydrologic indicator sites chosen to cover specified environmental objectives and targets, environmental water requirements or environmental demands. These sites are called hydrologic indicator sites. The hydrologic indicator sites and flows described at those sites are intended to represent the broader environmental flow needs of river valleys or reaches. The selection of sites and flows described focus on those areas and issues with greatest sensitivity to the environmentally sustainable level of take. Three hydrologic indicator sites were added for the Northern Basin Review.
