The Tuolumne River is more than just a source of water – it is the cornerstone of life across the region. The Don Pedro Project’s primary purpose is to serve as a reliable source of water and power under all conditions, including extended droughts. This is only possible with a thriving and vibrant ecosystem. That is why Turlock Irrigation District (TID) and Modesto Irrigation District (MID) have long taken a role protecting the Tuolumne River watershed.

Protecting Our Natural Resources

Ever since the Tuolumne River was first tapped as a water supply for a parched region, Turlock Irrigation District has taken a leading role as a steward of this precious resource.

Together with our partner the Modesto Irrigation District, TID has spent millions on studies to better better understand Fall Run Chinook Salmon and Rainbow Trout fisheries within the Tuolumne, along with ways to reduce predation and help these fish thrive.

Protecting and preserving habitat along the Tuolumne River is also an important part of this stewardship. Turlock Irrigation District spearheaded numerous restoration projects over the years.

Preserving Habitat

TID and MID led efforts for channel and riparian restoration, predator isolation and sediment management along the Tuolumne River. This includes bank reshaping and the Fox Grove streambed restoration.

Since 1983, $250,000 has been spent on equipment to remove woody debris in Don Pedro that poses threats to swimmers and boaters.

TID and MID have contributed millions of dollars on site-specific science to better understand Fall Run Chinook Salmon and Rainbow Trout.

Since the early 1980s, TID and MID have employed a full-time aquatic biologist to develop a greater understanding of the needs of Rainbow Trout and Fall Run Chinook Salmon.
