Grants Pass and surrounding areas in Josephine County continue to receive heavy rainfall this week as an intense storm system settles over Southern Oregon. Forecasters predict that by the time the system moves out later this week, rainfall totals could reach record levels not seen in many years. Although widespread flooding like that of past historic events is not anticipated at this time, officials and residents are keeping a close watch on river levels and urban drainage systems as the rain continues to fall.
The city of Grants Pass has a long history of dealing with flooding due to its location along the Rogue River and the many creeks and streams that flow through the area. The most devastating flood in local memory remains the infamous “Christmas Flood of 1964.” That event was triggered by a perfect storm of prolonged rainfall, rapid snowmelt, and swollen rivers, resulting in catastrophic flooding across much of Oregon and Northern California.
In Grants Pass, the Rogue River spilled far beyond its banks, inundating residential neighborhoods, businesses, roads, and bridges. Entire communities were cut off as water levels rose quickly, overwhelming any defenses that were in place at the time. Homes were evacuated, and significant portions of the city faced severe water damage. The 1964 flood not only left a lasting mark on the community but also led to years of planning, rebuilding, and implementing flood mitigation strategies to reduce the risk of future disasters.
Since then, city officials have worked to strengthen flood protection measures, improve drainage systems, and update the city’s floodplain management policies. Nevertheless, many low-lying areas remain vulnerable, and any prolonged period of heavy rain tends to bring concerns of flooding back to the forefront.
The current storm system impacting the region is expected to remain in place until at least Thursday, with an estimated total of 3 to 5 inches of rain falling in Grants Pass and nearby areas. In higher elevation zones and mountainous regions, rainfall amounts may exceed these totals. The Rogue River and its tributaries, including the Applegate and Illinois Rivers, are rising steadily, but so far remain below official flood stage levels.
Local creeks, however, have been reported to be running high and fast, and areas that typically experience minor flooding during large rain events are already seeing water collecting in fields and along road shoulders. Small streams and storm drains are at capacity in several locations, particularly in neighborhoods with older drainage infrastructure or near hillsides where runoff is intense.
Although major river flooding is not predicted at this time, urban and flash flooding remains a concern, especially if rain continues to fall at high rates in short periods. Roadways that are prone to water accumulation may become hazardous, and localized flooding in low-lying parts of the city is possible if the rain persists beyond current expectations.
Several parts of Grants Pass have historically been vulnerable to flooding, and these remain areas to watch closely. These include neighborhoods along Parkdale Drive, Fruitdale, and areas near Tussing Park. Parks adjacent to the Rogue River, including Baker Park, may also see rising water levels and partial inundation as the river swells.
City crews have been working to clear storm drains and remove debris that could cause blockages in the drainage system. Sandbags are available for residents concerned about water encroaching on homes and businesses. Distribution points include the Josephine County Public Works yard, and other designated city locations.
With rain expected to continue for several more days, residents are encouraged to monitor weather updates and take precautionary measures. Those living near creeks, rivers, and drainage ditches should remain alert for rapidly rising water levels. Motorists are urged to exercise caution, as standing water on roads can lead to dangerous driving conditions, including hydroplaning.
Residents should avoid walking or driving through flooded areas. Even shallow water on roadways can be hazardous, and deeper areas may have unseen dangers such as debris, sinkholes, or fast-moving currents.
Emergency officials recommend that households prepare for possible disruptions caused by heavy rainfall, including power outages and limited access to some roads. It is advised to have a supply of essentials such as drinking water, non-perishable food, flashlights, and batteries on hand in case of temporary isolation due to road closures.
Although this week’s rain is expected to be the heaviest the area has seen in a long time, forecasters believe the system will move eastward by late Thursday or early Friday. Afterward, the region is likely to see drier conditions returning over the weekend, allowing water levels to recede.
Even so, the days following heavy rain can still present hazards. With the ground already saturated, additional smaller storms or showers could easily trigger localized flooding or mudslides. Residents living on or below hillsides should remain cautious as saturated soils may shift.
Grants Pass and Josephine County officials continue to monitor the situation, coordinating with state and federal agencies to ensure that necessary resources are available should the situation worsen.
For now, while no repeat of the catastrophic 1964 flood is expected, this significant rain event serves as a reminder of the region’s vulnerability to extreme weather and the importance of ongoing preparedness.
