Revenue from the energy sales provides funds for other SWPB water project (which includes 22 dams and approximately 250 miles of irrigation canals) repairs and rehabilitations. Most of these large projects were completed in the 1930s and 1940s and have significant needs.

The facility is capable of generating roughly 56 million kilowatt-hours of electricity based on average river flows.  Gross revenue power sales in 2014 totaled $4,221,877; after debt repayments and operating expenses, approximately $1.3 million is available for use on other projects.
