Estes Park and the wider South Platte River Basin continue to face persistent drought conditions as winter approaches, with critically low snowpack levels reported for the week ending October 26, 2026. This follows the recently concluded Water Year 2026, which was Colorado's warmest on record by a substantial margin and also one of its driest, according to a report by Colorado State University researchers. The statewide drought remains very pronounced, with 83.50% of Colorado currently experiencing drought or abnormal dryness.
For the week ending October 26, 2026, the Snow Water Equivalent (SWE) in the South Platte Basin stands at 44% of the median, representing a significant 92% decrease in just one week. This figure is only 4% of the median peak, with 181 days remaining until that median peak is typically reached. Precipitation accumulation at SNOTEL stations in the basin registers at 79% of the median, down 15% from the previous week, and 5% of the total water year median, with 340 days left in the current water year. These figures underscore the challenging start to the accumulation season.
Recent data from October 20, 2026, shows some localized changes in drought intensity. Larimer, Weld, Boulder, Broomfield, and Adams counties within the South Platte River Basin saw one-category improvements in their drought status. However, Morgan County in the basin experienced a one-category degradation. Overall, the South Platte Basin is currently experiencing a range of conditions, from Abnormally Dry to Moderate, Severe, Extreme, and Exceptional drought. Historical data for 2026, 2018, 2012, and 2002 have been added to relevant climate graphs to highlight the ongoing severity of the statewide drought.
The severity of the drought is compounded by the findings of the Colorado State University report on Water Year 2026, which concluded in September. The report states that it was "one for the record books in Colorado," marking the warmest year on record by a significant margin and one of the driest. The mountain snowpack, in particular, was the lowest ever recorded, which had widespread implications across various sectors including agriculture, wildfire management, human health, and recreation. Statewide temperatures were an astonishing 4.5 degrees Fahrenheit above the averages observed between 1991-2020. The year included four months — December, January, March, and August — that were the warmest ever recorded for those respective months. Furthermore, 11 of the 12 months in Water Year 2026 ranked among the top-15 warmest of those months on record. The state surpassed the previous heat record set in 1934 by two degrees.
Looking ahead, the forecast for the coming days in the central and northern mountains includes a slight chance for snow showers on Saturday, October 26, 2026, followed by a chance for rain and snow showers on Sunday. In the northern mountains, there is a slight chance for showers on Saturday and a chance for showers on Sunday. Locally, a chance for showers is also expected on both Saturday and Sunday. The 7-day Quantitative Precipitation Forecast for the week of October 26, 2026, anticipates precipitation for the mountains of the South Platte River Basin, potentially totaling up to 0.10 inches.
Further into the future, the Climate Prediction Center's 8-14 day outlook, issued October 25, 2026, for the week starting November 2, 2026, projects above normal temperatures and above normal precipitation for the mountains of the South Platte River Basin. This potential for increased precipitation, if it materializes, could offer some relief to the parched region.
In contrast to the dry conditions locally, a substantial amount of water has been observed downstream of the Four Corners National Monument. The San Juan River is reportedly raging out of its banks, causing flooding in the Navajo Nation and contributing to a 10-foot rise in Lake Powell. While this significant water flow is occurring approximately 439 miles from the Estes Park area, it highlights the varied hydrological conditions across the wider region.
The Colorado 7-Day precipitation map through October 25, 2026, showed precipitation in the South Platte Basin along the Continental Divide of the Americas ranging from 0.00 to 1.75 inches. The corresponding percent of normal precipitation map indicated a range from 0% to 800% of normal for the same area, reflecting highly localized and uneven rainfall patterns. Temperature data also reflects departures from normal for the 7-day period through October 25, 2026, across Colorado, contributing to the overall climate picture. The persistence of extreme temperatures and low snowpack from the previous water year underscores the ongoing challenge for water resources in the South Platte Basin.
