Large-scale evacuations are taking place among residents of the low levels of Oroville and areas downstream after torrential rains led to the overflow of Lake Oroville in Northern California for first time in 48-year history, leading to what is said to be an imminent failure of the dam's spillway, which according to officials could "lead to a failure of the structure."

Many of us modern astrologers may have forgotten the work of Cyril Fagan, the pioneer who gave respectability to sidereal astrology. I feel that that it is important that we remember what he said:
It has long been the custom in this branch of astrology to consider maps drawn for the time of the entry of the Sun into the cardinal signs: Aries,Cancer,Libra and Capricorn. Of these, the Aries Ingress was by tradition considered the most important and possibly to be thought of as “the map of the year”. Led by Carter astrologers have begun to consider the Capricorn as the prime ingress.
It was Carter who suggested that if the sidereal zodiac were valid, maps for the entry of the Sun into the constellations of Aries,Cancer,Libra and Capricorn would be of importance. This suggestion was followed up by Garth Allen, who in an extensive statistical investigation found that the sidereal ingresses were not only valid but of the highest significance. This opinion has been fully confirmed by other investigators in recent years. Garth eventually arrived at the conclusion that the Capricorn Sidereal Ingress was of primary importance followed in rank by that of Cancer; Aries and Libra, whilst having some significance, could be considered of lesser importance.

Astrologers have discovered that progressing the Capricorn ingress chart on a daily basis can reveal important events. Shown here is the sidereal Capricorn ingress chart progressed to Feb.12, the date of the news. Notice that the T-square with Sun-Pluto at the apex reaches the horizon axis. The Jupiter-Uranus opposition forms the arms of the T. Uranus [21ar] is conjunct the theta (θ) Eridanus, Acamar, ia star in the River Eridanus often referred to as a dam . Ebertin links Uranus-Pluto with collapses and from the reference below we have:
Pluto in Capricorn  : collapse of infrastructure.
But going a little further we have on the Ascendant, the star Procyon, alpha Canis Minor which was part of the Chinese asterism Pe-Ho, the Northern River and the star xi Geminorum which was Tsi-Choui, the Accumulated Waters; or the Massed or Swollen Waters. A close eye was kept on this star to see if there was danger of summer floods; astrologers held that if one moment it looked bright and the next it faded away, rivers would overflow and fords and bridges would become impassable.
Finally, we also note that Neptune, the planet which rules lakes and rivers  also forms aspects to the progressed horizon axis. Putting the elements together we can see how the chart identifies the danger from waters overflowing from a lake.
