ALAMEDA, Calif. (AP) — Denny Glover was hoping for a big catch when he went fishing with buddies on the Sacramento River, but he wasn't expecting a fully grown humpback whale.
Glover saw the whale surfacing on Wednesday while he was fishing for salmon and striped bass from a 21-foot (6.4-meter) boat, less than half the length of the animal. He shot a few videos as the whale broke the surface of the water in California's largest river, about 60 miles (97 kilometers) from its more typical home of the Pacific Ocean.
“One of the guys on the boat, he said, ‘I see a whale.’ He saw the spout,” Glover said. “At first we didn't believe it. We thought he had mistaken a dolphin or a porpoise. Then we saw the spout again, and there's no mistaking a whale spout.”
The rare inland visit from a whale has attracted the attention of scientists who want to know what kind of condition it's in and how it wound up so far from the sea. The whale entered San Francisco Bay earlier in the week and has been traveling east in the Sacramento-San Joaquin Delta, California's largest river delta, The Marine Mammal Center said in a statement.
The center, which is in Sausalito, said its cetacean team is planning to assess and monitor the animal. The public should avoid interacting with the whale and trying to change its course, said Kathi George, the center's director of cetacean conservation biology.
“While it’s unknown whether this whale is just passing through or if there is an underlying, unknown ailment, the best thing people can do is experience this adult whale’s presence from a respectful distance,” George said.
The whale is known to researchers through a photo identification catalog and has been documented 15 times over the past 24 years, the center said. The most recent documented sighting before this week was in Baja California in February, the center said. Researchers don't know whether the whale is male or female.
The California Department of Fish and Wildlife and National Oceanic and Atmospheric Administration both declined to comment about this week's sighting.
The whale isn't the first to travel so far inland. In 1985, a humpback whale known as Humphrey spent several weeks in the Rio Vista area before returning to the ocean, The Marine Mammal Center said. A mother-calf pair known as Delta and Dawn spent nearly three weeks in the Sacramento River Delta in 2007 before returning, the center said. The whales eventually made their way back to the ocean, the center said.
Humpback whales are among the largest animals on Earth and can weigh up to 80,000 pounds (35,287 kilograms). They are known for their dramatic lunges at the water's surface, an activity called breaching, and their complex underwater songs.
Seeing the whale so far upriver was a thrill, Glover said. The animal seemed in good shape despite being far from home, he added.
“It came up and went down in fairly regular intervals,” he said. “It was moving along at a fair clip. It wasn't acting erratically other than that it was upstream in a freshwater river.”

Iran says it struck an oil tanker trying to transit the Strait of Hormuz, while hundreds of thousands of people rallied in Tehran in the largest show of support for the government since the United States and Israel launched attacks in February.
Meanwhile, South Korea says it is considering expanding a naval operation in the Gulf of Aden to protect its ships and oil-shipping routes, but it will not send troops to intervene in the Iran war.
Here is the latest news from the Middle East on Friday. Full coverage is available here.
Iran said it struck the Togo-flagged oil tanker Trend over what it described as an “illegal attempt” to pass through the Strait of Hormuz on Thursday night, according to the state broadcaster, which cited the Revolutionary Guard Corps.
The Associated Press could not immediately confirm the report.
The Guard's navy warned that vessels attempting to pass through the strait without authorization would face “destruction,” the broadcaster said. Tehran has asserted control over much of the waterway since the U.S. and Israel launched the war on Feb. 28.
Separately, the United Kingdom Maritime Trade Operations, which alerts about attacks or military operations, said another tanker was struck Wednesday by an “unknown projectile” while transiting out of the strait, with the crew reported safe. No other details were available.
Hundreds of thousands of Iranians filled the streets of Tehran in the biggest rally since the war began in February, pledging to take up arms as “Janfaday-e Iran,” or those “who sacrifice their lives for Iran.”
Iran’s government has sought to rally the people and stress national unity, even as the economy worsens under a U.S. naval blockade of Iranian ports and new U.S. sanctions meant to increase Tehran’s economic pain.
Some participants trampled flags of the U.S. and Israel. Others chanted “Death to America” and “Death to Israel.”
The president of the breakaway Somali republic of Somaliland is seeking greater recognition from the United States and offering the potential of military and commercial access to the territory’s Gulf of Aden coast in return.
After concluding various meetings with U.S. officials and lawmakers, President Abdirahman Mohamed Abdullahi said Friday that establishing a U.S. diplomatic post in the capital of Hargeisa or the city of Berbera — a major port near the entrance to the Red Sea and the Bab el-Mandeb Strait that has played a critical role in the U.S. war with Iran — is a priority for his government.
A number of U.S. lawmakers have called for the Trump administration to recognize Somaliland as an independent country, particularly after Israel did so earlier this year.
While the Trump administration still continues to recognize the territorial integrity of Somalia, which includes Somaliland.
Hundreds of people rallied in northern areas of Yemen in support of the Houthis and to protest Saudi Arabia’s accusation that the rebels targeted Islam’s holiest site, Mecca.
Houthi-controlled Al-Masirah TV showed protesters carrying pictures of the Kaaba, a landmark in Mecca, along with Yemeni, Iranian, Lebanese and Palestinian flags. A speaker reiterated the Houthis’ opposition to Saudi Arabia, which supports Yemen's internationally recognized government.
The Saudis said they intercepted a Houthi drone targeting Mecca earlier this week. The Houthi leadership has denied responsibility.
The Iran-backed Houthis are fighting Saudi-backed Yemeni forces, and the conflict recently has fueled mass displacement of more than 100,000 people.
Container ships and oil tankers continued to transit the Bab el-Mandeb Strait after the Houthis said they are only targeting Saudi-linked vessels. But a dip in traffic has been reported over the last week after a lightning advance by Houthis on islands in the waterway.
About 26-35 vessels per day have transited this week, down from the 35-40 daily average of the prior eight weeks, according to Dimitris Ampatzidis, Maritime Risk & Compliance Manager at Kpler.
Many shipping companies abandoned the route after Houthi attacks on Israeli-linked vessels began in 2023, though vessels from Russia and China appear to have no trouble.
“Traffic remains severely impaired and increasingly selective,” said Mohamed Kotb with United Insurance Brokers in London.
South Korean President Lee Jae Myung said his government is considering expanding the operations of a naval unit deployed in the Gulf of Aden off the coasts of Yemen and Somalia to protect his country’s vessels and oil shipping routes.
But he stressed that South Korea would not take action that would draw it into the U.S.-Iran conflict, pushing back against recent pressure from the Trump administration. South Korea has deployed the anti-piracy Cheonghae Unit for years.
The growing threat from Houthis in Yemen to shipping in the region has alarmed countries and markets, even though the rebels have said they are only targeting the assets of neighboring Saudi Arabia, the world's top oil exporter.
“There will be no troop deployment that involves or intervenes in the war,” Lee said.
In Lebanon, the state-run National News Agency said the Israeli army threw stun grenades where Lebanese army forces were stationed at the entrance to the town of Deir Mimas.
The Israeli military said in a statement that the Lebanese army had entered what Israel refers to as the “security zone," an area the Israeli army occupied during its latest war with Hezbollah, and established roadblocks "without prior coordination.”
A Lebanese security official said the soldiers wanted to escort villagers to their olive orchards and the area was not part of a security zone. He said Lebanese soldiers eventually withdrew. He spoke on condition of anonymity because he was not authorized to comment publicly.
In June, Lebanon and Israel reached an agreement under which Israeli forces would gradually withdraw from occupied areas in southern Lebanon and allow the Lebanese army to take control, in exchange for disarmament of Hezbollah. There has been little progress in implementing the deal.
