Bartlett Dam Height Increase Project
Sector: Water Supply and Storage • Location: Arizona, United States
Source: National Audubon Society
The project involves raising the height of Bartlett Dam in central Arizona to increase the storage capacity of Bartlett Reservoir. Two modification scenarios are proposed: raising the dam by 101.8 feet to store up to 628,000 acre-feet of water, or raising it by 60.8 feet to store up to 422,000 acre-feet. This aims to compensate for sediment build-up in the upstream Horseshoe Reservoir, which has r

Description
Description | The project involves raising the height of Bartlett Dam in central Arizona to increase the storage capacity of Bartlett Reservoir. Two modification scenarios are proposed: raising the dam by 101.8 feet to store up to 628,000 acre-feet of water, or raising it by 60.8 feet to store up to 422,000 acre-feet. This aims to compensate for sediment build-up in the upstream Horseshoe Reservoir, which has reduced its water storage capacity. The project includes environmental impact assessments and habitat analyses to understand the effects of the larger reservoir footprint. |
