New part of Arizona border wall is dangerous for rare fish
PHOENIX — A newly built segment of the southern Arizona border wall may bolster national security, but it will endanger one of the rarest desert fish in the U.S., according to the Center for Biological Diversity.
The Sonora chub in Arizona is one of only two populations of the species in the U.S. and is protected under the Endangered Species Act. The fish live in the California Gulch, a stream in the western portion of the Atascosa Highlands, a region consisting of three small mountain ranges along the international border just west of Nogales.
The newly built border wall and paved road have impeded the flow of the stream where the fish live, according to a report the center released Wednesday.
The desert fish, a minnow that grows up to 20 centimeters in length, also feeds off of many native food sources in the surrounding streams. Though its Arizona population has remained steady since its discovery in 1995, the Center for Biological Diversity is concerned new infrastructure will push the fish to the brink.
Krista Kemppinen, a senior scientist at the center, said new border infrastructure is cutting this population off from its lifeline in Sonora.
“Designating California Gulch as critical habitat is more urgent than ever to minimize other threats, such as by keeping cows out of the Sonora chub’s pools,” Kemppinen said in a press release.
She also shared ideas for steps federal authorities can take to balance border security with environmental preservation.
“It’s also imperative that carefully designed culverts be added to the new border infrastructure to allow at least some semblance of a natural streamflow and migration. If federal officials are serious about saving this fish, they need to act now,” Kemppinen said.
What progress is being made to protect the fish from the new Arizona border wall segment?
Time is of the essence because the U.S. Fish and Wildlife Service previously stated it would not act on a request to help preserve the fish’s habitat until 2027 at the earliest.
This announcement followed a 36-page petition submitted by the Center for Biological Diversity in March 2023.
Kemppinen said authorities should designate four miles of the fish’s native area in Arizona as critical habitat.
“The Sonora chub’s survival depends on being able to access scarce desert water on both sides of the border, exchange genetic material with nearby populations in Mexico, and bolster its populations with upstream migrations of fish from Sonora after droughts,” Kemppinen said. “The new construction makes all that impossible.”
Besides access to water, other threats to the Sonora chub include uranium mining, nearby livestock grazing and recreational activity like the creation of hiking trails.
PHOENIX — The number of legal challenges to detentions in Arizona and nationwide has grown to record highs.
Immigration Attorney Hugo Balderas Ibarra said when someone is picked up by ICE, typical bond hearings are “pretty much out the window.”
“These policies that the administration is implementing violate the due process, violate fifth amendment,” Balderas Ibarra said.
This has led attorneys representing detained individuals to file what’s known as a habeas corpus petition.
“A habeas corpus petition is something in federal court that says the federal government is detaining me or confining me somewhere without basis in law,” New Frontier Immigration Law founder Hillary Walsh said.
Walsh said she filed three petitions on Friday alone.
“One of these is for an 18-year-old kid who has no criminal history,” Walsh said. “He came here to seek asylum a few years ago, and went through the whole process legally, asked at the border, did everything right, and now he’s detained.”
Data by TRAC shows the surge in the federal filings alleging illegal detention over the past year.
From 105 nationally in March 2025, to 9,059 the same month this year.
In Arizona, more than 1,100 cases have been filed between October and March, according to TRAC.
“A lot more people who are being detained, but we also have a whole other layer to the process for getting them out if they’re eligible for bond, and so that clogs up the whole federal court system,” Walsh said.
As the Iowa State Cyclones continue to reflect on what was a strong season, one of their top players from last year is in the portal and is the best player available.
After deciding to come back to college a couple of days ago, Milan Momcilovic is now the best player in the portal and has a number of suitors looking to bring him in. Due to the large amount of money that he is expected to get, it would be a complete shock if he came back to Iowa State at this point. However, where he goes could have an impact on the program.
Last season, the junior had a breakout year and emerged as one of the best shooters in the country. While there is still work to be done to translate his game to the next level, he is an impact player in college basketball.
However, where he might go is the big decision everyone is waiting to see. Currently, it appears to be a three-horse race between the Arizona Wildcats, Kentucky Wildcats, and the Louisville Cardinals. Of the three, the Cyclones certainly don’t want to see him go to one of those schools.
Momcilovic Choosing Arizona Would Be a Tough Blow
If the star shooter for the Cyclones were to choose the Wildcats, it would be a tough blow for Iowa State. While the Cyclones had a great season this year, it was Arizona that was a thorn in their side.
The Wildcats were able to beat them both in their regular-season matchup and then again in the Big 12 tournament. The game in the Big 12 was an absolute thriller and went right down to the wire.
While Iowa State might have lost, it was Momcilovic who had a fantastic game in the showdown. Now, as the talented sharpshooter mulls his decision on where to play next year, seeing him go to Arizona would be a tough blow for the Cyclones.
This was a team that beat them twice last year, and taking one of their best players would likely result in the Wildcats being considered a better team heading into next season as well.
While Iowa State did a great job in the transfer portal and has some young talent coming back, losing the best three-point shooter in the country is a big blow. Furthermore, since Kentucky and Louisville aren’t in the Big 12, seeing Momcilovic join one of those squads wouldn’t sting or have an impact on the Cyclones nearly as much.
