California replaced a fish-blocking pipe on Fort Goff Creek with a bridge in 2014; later monitoring found 64 Chinook salmon nests upstream
In California, the removal of the culvert on Fort Goff Creek has significantly enhanced fish passage, particularly for salmon. Completed in 2014, a new bridge now connects fish to breeding grounds that were previously inaccessible. Biologists found 64 nests of Chinook salmon in this newly opened habitat, highlighting the importance of addressing culverts nationwide to improve aquatic ecosystems and connectivity.
If AI unwinding pulls power stocks down, mind the difference between narrative and business: 6 stocks with upside potential of up to 30%
It is quite possible that, over the coming weeks, the narrative on the street could be that power stocks, which many had started to treat as a kind of proxy for the AI build-out, would come under pressure. But linking these stocks to global unwinding in the AI trade could be a mistake because demand for power in India depends on something far bigger and far older.

Here’s one thing that is worth clarifying, because it is in the headlines. Large global technology companies have been announcing heavy spending on AI, and there has been some correction in those stocks because of it. It is natural to worry that this will spill over into the Indian market. It most likely will not.
For investors with ability to look past the current bearish narrative: 5 large-cap stocks with upside potential of up to 34%
One stock not falling on bad news does not mean the worst is over for the whole market. It may mean only that the bears have, for now, taken out of that one stock all that they wanted to. The broader pressure can still come back. So this is a small positive, and it should be considered just that, and nothing more.
Arunachal Pradesh faces protests over 11,000-MW Siang dam, 1,605-MW Subansiri project
Protests erupted in Arunachal Pradesh over proposed hydropower projects, causing violent clashes and significant unrest. People oppose the Siang Upper Multipurpose Project and the Subansiri Upper Hydroelectric Project, voicing concerns over environmental damage. Chief Minister Pema Khandu emphasized the need for careful assessment of the projects before proceeding. The proposed developments are linked to fears of water security due to China's dam projects upstream.
Arunachal’s anti-dam protests spread as agitators oppose 1,605 MW Menga hydropower project
In Arunachal Pradesh, opposition to the 1,605 MW Subansiri Upper Hydroelectric Project is growing fierce. A bandh organized by student groups has brought normal activities to a halt, impacting transportation services. Protesters are pushing for the cancellation of the project, raising alarms over potential environmental damage and safety hazards. Incidents of property damage and clashes with law enforcement have been documented.
Dam in China trapped millions of tonnes of water, rising 7 feet daily and threatening millions. How did engineers avert disaster?
The 2008 Wenchuan earthquake triggered a massive landslide that blocked China's Tongkou River, creating the unstable Tangjiashan lake and threatening millions downstream. Authorities evacuated residents and airlifted heavy machinery to carve a controlled drainage channel through the natural dam. The operation averted a catastrophic flood and informed landslide-dam management strategies later applied during China's 2018 Baige landslide crisis.
These large- and mid-cap stocks can give more than 20% return in 1 year, according to analysts
The mayhem in the market is likely to continue, at least for the short-term. Nothing has changed in terms of the known headwinds: The US-Iran war continues in fits and starts, oil prices are still elevated, US bond rates remain high, and global supply chains continue to be disrupted. With the calendar year-end approaching, however, there is a technical factor that has entered the mix.
Washington used 1 pneumatic fish cannon to solve salmon passage past a 60m hydroelectric dam; the result transformed blocked rivers into thriving spawning grounds
Washington used 1 pneumatic fish cannon to solve salmon passage past a 60m hydroelectric dam, using a pneumatic tube system to move migrating fish over major barriers. The Whooshh PassagePortal, also called the Salmon Cannon, helped transport salmon around dams while reducing handling. The system uses scanning, sorting, water mist and controlled air pressure. The technology helped reopen access to upstream waters used by salmon for spawning.
The war will pass; AI and its ecosystem will not: 5 large-cap stocks with an upside potential of up to 33%
A war affects the mood of the market, but it does not affect every underlying business equally. There are sectors where the demand is driven by something far deeper and longer-lasting than any conflict. And those sectors carry on growing, whatever a president says, or a rebel group does.

In 2024, four dams were removed from an American river. Over 400 miles of Salmon habitat reopened. Scientists are now watching an ecosystem rebuilding itself
Four hydroelectric dams on the Klamath River were removed in 2024. This project opened over 400 miles of historic salmon habitat. Indigenous communities and ecosystems will benefit from this significant ecological recovery. Scientists are now monitoring the river's health and salmon populations. The dam removal marks a new chapter for the Klamath River's future.
The U.S. Army Corps of Engineers spent $7 million on fish ladders in 1938 to move salmon past Bonneville Dam; decades later, the system carries 1 million a season in good years
The Bonneville Dam’s fish ladders, designed as part of a New Deal initiative, remain operational after decades of service. The construction saw a notable increase in budget allocation. Annually, millions of fish traverse these ladders, predominantly hatchery-reared. However, wild salmon populations continue to dwindle, impacted by upstream dams and climate change, underscoring persistent environmental challenges despite the fish ladders' effectiveness.
Maryland spent $12 million on a fish lift in 1991 to move American shad past Conowingo Dam; decades later, annual runs remained far below the 2 million-fish target
Maryland invested $12 million in a fish lift to help migrating shad overcome the Conowingo Dam. This technological solution proved ineffective, moving only a fraction of the targeted fish annually. Experts now favor dam removal over fish passage structures like lifts and ladders. The state is investing $340 million in environmental upgrades and trucking fish past the dam. This situation reflects costly infrastructure projects that under-delivered on their initial goals.
Four dams built on the Klamath River between 1918 and 1966 made power, not water storage; in 2024, the last came down, reopening 420 miles of salmon habitat
In a groundbreaking initiative, four dams on the Klamath River spanning California and Oregon have been dismantled after a century of existence, revitalizing roughly 420 miles of crucial salmon habitat. Following years of intense discussions, the demolition was completed in October 2024. Experts predict a resurgence in salmon populations over the next twelve to twenty-five years as ongoing restoration efforts, costing millions, take effect.
In 2012, PacifiCorp launched a trap-and-haul program to move adult salmon upstream past Merwin Dam. 14 years later, researchers found 2 stages in the system but 1 decisive bottleneck: young salmon failing to find the artificial current downstream
A trap-and-haul program on Washington’s Lewis River helps adult Chinook salmon bypass Merwin Dam by transporting them in trucks to upstream spawning habitat. But researchers tracking the salmon life cycle have identified a major weakness on the return journey. Juvenile salmon, or smolts, must travel downstream toward the Pacific Ocean, yet many struggle to locate the artificial current leading to a floating collection system near Swift Dam. Once captured, they can be transported safely downstream, but low capture rates remain the program’s primary bottleneck.
India said to have cut water flow through Baglihar dam after Indus Treaty suspension
Following a terror attack in Jammu and Kashmir, India has halted water flow through the Baglihar Dam on the Chenab River and plans similar actions at the Kishanganga Dam on the Jhelum. These hydroelectric dams provide India with the ability to control water release timings, a move that impacts the Indus Waters Treaty between India and Pakistan.
