DENVER (AP) — For National Park Service fisheries biologist Jeff Arnold, it was a moment he’d been dreading. Bare-legged in sandals, he was pulling in a net in a shallow backwater of the lower Colorado River last week, when he spotted three young fish that didn’t belong there. “Give me a call when you get this!” he messaged a colleague, snapping photos.


Minutes later, the park service confirmed their worst fear: smallmouth bass had in fact been found and were likely reproducing in the Colorado River below Glen Canyon Dam.

They may be a beloved sport fish, but smallmouth bass feast on humpback chub, an ancient, threatened fish that’s native to the river, and that biologists like Arnold have been working hard to recover. The predators wreaked havoc in the upper river, but were held at bay in Lake Powell where Glen Canyon Dam has served as a barrier for years — until now. The reservoir’s recent sharp decline is enabling these introduced fish to get past the dam and closer to where the biggest groups of chub remain, farther downstream in the Grand Canyon.

There, Brian Healy has worked with the humpback chub for more than a decade and founded the Native Fish Ecology and Conservation Program.

“It’s pretty devastating to see all the hard work and effort you’ve put into removing other invasive species and translocating populations around to protect the fish and to see all that effort overturned really quickly,” Healy said.

As reservoir levels drop, non-native fish that live in warm surface waters in Lake Powell are edging closer to the dam and its penstocks — submerged steel tubes that carry water to turbines, where it generates hydroelectric power and is released on the other side.

If bass and other predator fish continue to get sucked into the penstocks, survive and reproduce below the dam, they will have an open lane to attack chub and other natives, potentially unraveling years of restoration work and upending the Grand Canyon aquatic ecosystem — the only stretch of the river still dominated by native species

The apostle Paul, in his second letter to the Thessalonians, foretold the great apostasy which would result in the establishment of the papal power. He declared that the day of Christ should not come, “except there come a falling away first, and that man of sin be revealed, the son of perdition; who opposeth and exalteth himself above all that is called God, or that is worshiped; so that he as God sitteth in the temple of God, showing himself that he is God.” And furthermore, the apostle warns his brethren that “the mystery of iniquity doth already work.” 2 Thessalonians 2:3, 4, 7. Even at that early date he saw, creeping into the church, errors that would prepare the way for the development of the papacy.
Little by little, at first in stealth and silence, and then more openly as it increased in strength and gained control of the minds of men, “the mystery of iniquity” carried forward its deceptive and blasphemous work. Almost imperceptibly the customs of heathenism found their way into the Christian church. The spirit of compromise and conformity was restrained for a time by the fierce persecutions which the church endured under paganism. But as persecution ceased, and Christianity entered the courts and palaces of kings, she laid aside the humble simplicity of Christ and His apostles for the pomp and pride of pagan priests and rulers; and in place of the requirements of God, she substituted human theories and traditions. The nominal conversion of Constantine, in the early part of the fourth century, caused great rejoicing; and the world, cloaked with a form of righteousness, walked into the church. Now the work of corruption rapidly progressed. Paganism, while appearing to be vanquished, became the conqueror. Her spirit controlled the church. Her doctrines, ceremonies, and superstitions were incorporated into the faith and worship of the professed followers of Christ.
This compromise between paganism and Christianity resulted in the development of “the man of sin” foretold in prophecy as opposing and exalting himself above God. That gigantic system of false religion is a masterpiece of Satan’s power—a monument of his efforts to seat himself upon the throne to rule the earth according to his will.
Satan once endeavored to form a compromise with Christ. He came to the Son of God in the wilderness of temptation, and showing Him all the kingdoms of the world and the glory of them, offered to give all into His hands if He would but acknowledge the supremacy of the prince of darkness. Christ rebuked the presumptuous tempter and forced him to depart. But Satan meets with greater success in presenting the same temptations to man. To secure worldly gains and honors, the church was led to seek the favor and support of the great men of earth; and having thus rejected Christ, she was induced to yield allegiance to the representative of Satan—the bishop of Rome.
It is one of the leading doctrines of Romanism that the pope is the visible head of the universal church of Christ, invested with supreme authority over bishops and pastors in all parts of the world. More than this, the pope has been given the very titles of Deity. He has been styled “Lord God the Pope” (see Appendix), and has been declared infallible. He demands the homage of all men. The same claim urged by Satan in the wilderness of temptation is still urged by him through the Church of Rome, and vast numbers are ready to yield him homage.
But those who fear and reverence God meet this heaven-daring assumption as Christ met the solicitations of the wily foe: “Thou shalt worship the Lord thy God, and Him only shalt thou serve.” Luke 4:8. God has never given a hint in His word that He has appointed any man to be the head of the church. The doctrine of papal supremacy is directly opposed to the teachings of the Scriptures. The pope can have no power over Christ’s church except by usurpation.
Romanists have persisted in bringing against Protestants the charge of heresy and willful separation from the true church. But these accusations apply rather to themselves. They are the ones who laid down the banner of Christ and departed from “the faith which was once delivered unto the saints.” Jude 3.
Satan well knew that the Holy Scriptures would enable men to discern his deceptions and withstand his power. It was by the word that even the Saviour of the world had resisted his attacks. At every assault, Christ presented the shield of eternal truth, saying, “It is written.” To every suggestion of the adversary, He opposed the wisdom and power of the word. In order for Satan to maintain his sway over men, and establish the authority of the papal usurper, he must keep them in ignorance of the Scriptures. The Bible would exalt God and place finite men in their true position; therefore its sacred truths must be concealed and suppressed. This logic was adopted by the Roman Church. For hundreds of years the circulation of the Bible was prohibited. The people were forbidden to read it or to have it in their houses, and unprincipled priests and prelates interpreted its teachings to sustain their pretensions. Thus the pope came to be almost universally acknowledged as the vicegerent of God on earth, endowed with authority over church and state.
The detector of error having been removed, Satan worked according to his will. Prophecy had declared that the papacy was to “think to change times and laws.” Daniel 7:25. This work it was not slow to attempt. To afford converts from heathenism a substitute for the worship of idols, and thus to promote their nominal acceptance of Christianity, the adoration of images and relics was gradually introduced into the Christian worship. The decree of a general council (see Appendix) finally established this system of idolatry. To complete the sacrilegious work, Rome presumed to expunge from the law of God the second commandment, forbidding image worship, and to divide the tenth commandment, in order to preserve the number.
The spirit of concession to paganism opened the way for a still further disregard of Heaven’s authority. Satan, working through unconsecrated leaders of the church, tampered with the fourth commandment also, and essayed to set aside the ancient Sabbath, the day which God had blessed and sanctified (Genesis 2:2, 3), and in its stead to exalt the festival observed by the heathen as “the venerable day of the sun.” This change was not at first attempted openly. In the first centuries the true Sabbath had been kept by all Christians. They were jealous for the honor of God, and, believing that His law is immutable, they zealously guarded the sacredness of its precepts. But with great subtlety Satan worked through his agents to bring about his object. That the attention of the people might be called to the Sunday, it was made a festival in honor of the resurrection of Christ. Religious services were held upon it; yet it was regarded as a day of recreation, the Sabbath being still sacredly observed.
To prepare the way for the work which he designed to accomplish, Satan had led the Jews, before the advent of Christ, to load down the Sabbath with the most rigorous exactions, making its observance a burden. Now, taking advantage of the false light in which he had thus caused it to be regarded, he cast contempt upon it as a Jewish institution. While Christians generally continued to observe the Sunday as a joyous festival, he led them, in order to show their hatred of Judaism, to make the Sabbath a fast, a day of sadness and gloom.
In the early part of the fourth century the emperor Constantine issued a decree making Sunday a public festival throughout the Roman Empire. (See Appendix.) The day of the sun was reverenced by his pagan subjects and was honored by Christians; it was the emperor’s policy to unite the conflicting interests of heathenism and Christianity. He was urged to do this by the bishops of the church, who, inspired by ambition and thirst for power, perceived that if the same day was observed by both Christians and heathen, it would promote the nominal acceptance of Christianity by pagans and thus advance the power and glory of the church. But while many God-fearing Christians were gradually led to regard Sunday as possessing a degree of sacredness, they still held the true Sabbath as the holy of the Lord and observed it in obedience to the fourth commandment.
The archdeceiver had not completed his work. He was resolved to gather the Christian world under his banner and to exercise his power through his vicegerent, the proud pontiff who claimed to be the representative of Christ. Through half-converted pagans, ambitious prelates, and world-loving churchmen he accomplished his purpose. Vast councils were held from time to time, in which the dignitaries of the church were convened from all the world. In nearly every council the Sabbath which God had instituted was pressed down a little lower, while the Sunday was correspondingly exalted. Thus the pagan festival came finally to be honored as a divine institution, while the Bible Sabbath was pronounced a relic of Judaism, and its observers were declared to be accursed.
The great apostate had succeeded in exalting himself “above all that is called God, or that is worshiped.” 2 Thessalonians 2:4. He had dared to change the only precept of the divine law that unmistakably points all mankind to the true and living God. In the fourth commandment, God is revealed as the Creator of the heavens and the earth, and is thereby distinguished from all false gods. It was as a memorial of the work of creation that the seventh day was sanctified as a rest day for man. It was designed to keep the living God ever before the minds of men as the source of being and the object of reverence and worship. Satan strives to turn men from their allegiance to God, and from rendering obedience to His law; therefore he directs his efforts especially against that commandment which points to God as the Creator.
Protestants now urge that the resurrection of Christ on Sunday made it the Christian Sabbath. But Scripture evidence is lacking. No such honor was given to the day by Christ or His apostles. The observance of Sunday as a Christian institution had its origin in that “mystery of lawlessness” (2 Thessalonians 2:7, R.V.) which, even in Paul’s day, had begun its work. Where and when did the Lord adopt this child of the papacy? What valid reason can be given for a change which the Scriptures do not sanction?
In the sixth century the papacy had become firmly established. Its seat of power was fixed in the imperial city, and the bishop of Rome was declared to be the head over the entire church. Paganism had given place to the papacy. The dragon had given to the beast “his power, and his seat, and great authority.” Revelation 13:2. And now began the 1260 years of papal oppression foretold in the prophecies of Daniel and the Revelation. Daniel 7:25; Revelation 13:5-7. (See Appendix.) Christians were forced to choose either to yield their integrity and accept the papal ceremonies and worship, or to wear away their lives in dungeons or suffer death by the rack, the fagot, or the headsman’s ax. Now were fulfilled the words of Jesus: “Ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death. And ye shall be hated of all men for My name’s sake.” Luke 21:16, 17. Persecution opened upon the faithful with greater fury than ever before, and the world became a vast battlefield. For hundreds of years the church of Christ found refuge in seclusion and obscurity. Thus says the prophet: “The woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and three-score days.” Revelation 12:6.
The accession of the Roman Church to power marked the beginning of the Dark Ages. As her power increased, the darkness deepened. Faith was transferred from Christ, the true foundation, to the pope of Rome. Instead of trusting in the Son of God for forgiveness of sins and for eternal salvation, the people looked to the pope, and to the priests and prelates to whom he delegated authority. They were taught that the pope was their earthly mediator and that none could approach God except through him; and, further, that he stood in the place of God to them and was therefore to be implicitly obeyed. A deviation from his requirements was sufficient cause for the severest punishment to be visited upon the bodies and souls of the offenders. Thus the minds of the people were turned away from God to fallible, erring, and cruel men, nay, more, to the prince of darkness himself, who exercised his power through them. Sin was disguised in a garb of sanctity. When the Scriptures are suppressed, and man comes to regard himself as supreme, we need look only for fraud, deception, and debasing iniquity. With the elevation of human laws and traditions was manifest the corruption that ever results from setting aside the law of God.
Those were days of peril for the church of Christ. The faithful standard-bearers were few indeed. Though the truth was not left without witnesses, yet at times it seemed that error and superstition would wholly prevail, and true religion would be banished from the earth. The gospel was lost sight of, but the forms of religion were multiplied, and the people were burdened with rigorous exactions.
They were taught not only to look to the pope as their mediator, but to trust to works of their own to atone for sin. Long pilgrimages, acts of penance, the worship of relics, the erection of churches, shrines, and altars, the payment of large sums to the church—these and many similar acts were enjoined to appease the wrath of God or to secure His favor; as if God were like men, to be angered at trifles, or pacified by gifts or acts of penance GC 49.1 – GC 55.3

On the brink of extinction decades ago, the chub has come back in modest numbers thanks to fish biologists and other scientists and engineers. Agencies spend millions of dollars annually to keep intruders in check in the upper portion of the river.

Under the Endangered Species Act, government agencies are required to operate in ways that will not “jeopardize the continued existence” of listed animals. That includes infrastructure.

Even before the discovery of smallmouth bass spawning below the dam, agencies had been bracing for this moment. The U.S. Bureau of Reclamation recently enlisted a team of researchers at Utah State University to map the nonnative fish in Lake Powell and try to determine which could pass through the dam first.

A task force quickly assembled earlier this year to address the urgency the low water poses for native fish. Federal, state and tribal leaders are expected to release a draft plan in August containing solutions for policymakers who intend to delay, slow and respond to the threat of smallmouth bass and other predators below the dam.


There are a variety of solutions, but many will require significant changes to infrastructure.

In the meantime, National Park Service, U.S. Geological Survey and Arizona Game and Fish Department are moving quickly to try to contain the issue. During an emergency meeting, they decided to increase their monitoring efforts in other shallow areas and block off the entire backwater where the smallmouth bass were found so they can’t swim out into the river.

“Unfortunately, the only block nets we have are pretty large mesh, so it will not stop these smaller fish from going through, but it will keep the adults from going back out,” Arnold said, noting it’s the best they can do with available resources.

Experts say leaving more water in Lake Powell would be the best solution to ensure cool water can be released through the dam, although it’s tough to do in a river under so much stress.

Last month, the Department of the Interior notified the seven western states that depend on Colorado River water that they must devise a way to conserve up to 4 million acre-feet of water in 2023 — more than Arizona and Nevada’s share combined — or face federal intervention. It is unclear where that conserved supply would be stored, but Healy says he hopes Lake Powell is being considered.

“If we want to protect some of the values for which Grand Canyon National Park was established, we need to really think about how water is stored,” Healy said. “That issue needs to be at the table.”
