A month has passed since the devastating floods on the Front Range, and it\u2019s a little easier to discuss the positive effects of the extraordinary rain event for the impacted area, and across Colorado.<\/p>\n

The first was the significant drought relief that the rains brought, as shown in the U.S. Drought Monitor. The Drought Monitor synthesizes several different drought indicators into a single scale of drought severity, ranging from D0 (abnormally dry; conditions are generally below the 30th<\/sup> percentile) to D4 (exceptional drought; conditions are generally below the 2nd<\/sup> percentile).<\/p>\n

\"\"<\/a><\/p>\n

Prior to the rain event, conditions on the Front Range ranged from no drought in western Boulder and Larimer Counties, to D3 (extreme drought) in parts of Pueblo County, with a large swath of D1 (moderate drought) and D2 (severe drought) in between. After the 6\u201d to 18\u201d of rain\u2014roughly 25% to 100% of average annual precipitation falling in one week\u2014all of the Front Range was upgraded by one to three categories, with the drought-free area expanding to cover most of the urban areas and the northern headwaters of the South Platte River. The rest of Colorado also benefited from the lesser\u2014yet still well-above-average\u2014precipitation amounts received there.<\/p>\n

In addition, while most of the flood runoff rolled out of the state without being stored, the small to mid-sized Front Range reservoirs with direct stream inflows like Gross Reservoir refilled at a time of year when storage is usually declining fast from an early-summer peak.<\/p>\n

\"\"<\/a><\/p>\n

On the other side of the Continental Divide, larger reservoirs like Dillon Reservoir also got a big boost. Even enormous Lake Powell far downstream on the Colorado River saw a gain of about 200,000 acre-feet\u2014nearly the entire capacity of Dillon Reservoir\u2014during a period in which it was expected to decline by half that amount. The rains also led to a dramatic reduction in outdoor and agricultural water use<\/em>, which also benefited the reservoirs.<\/p>\n
