Here’s a report from (Wayne Harrison). From the article:

The monsoon moisture moved from the southwest to northeast across the metro area, pounding the downtown area starting just after 9 p.m.

From The Denver Post (Joey Bunch):

Areas north and southeast of the metro area had tornado and flood warnings through the evening, accompanied by 4 inches of rain, according to the National Weather Service. Northwestern Elbert County saw its “most severe flooding in at least a decade,” the National Weather Service said, relaying information from a trained weather spotter who reported more than 5 inches of rain southwest of Agate.

“The storms should not be as widespread (as Tuesday),” says meteorologist Jennifer Broome. “Even an inch of rain could cause some street flooding since the ground is saturated.”

“The Mountains can expect drier conditions today with only a slight chance for afternoon t-storms,” says meteorologist Chris Tomer. “Our weather pattern continues to dry out through Saturday. The Monsoon eases.”

Fromthe Montrose Daily Press (Katharhynn Heidelberg):

Montrose can blame its recent soaking on the early arrival of “monsoonal” sub-tropical moisture, the National Weather Service says. Measurements at Montrose Regional Airport show the area approached the 1-inch mark in precipitation for the period from July 5-10, with 0.91 inches overall, said Jim Pringle, a meteorologist with the weather service’s Grand Junction office…

The moisture is flowing up from Mexico, Central America and the eastern Pacific, and though it could clear out later in the week, it’s expected to again slide westward in the middle of next week.

From the Summit Daily News:

As of Monday, Denver Water was releasing 1,890 cubic feet per second of water from the Dillon Reservoir to prevent overflow, according to Bob Steger, manager of raw water supply for Denver Water. The release is planned to stay at that rate for the time being. Steger said the inflow into the reservoir has been dropping slowly, but is still high. The July 8, 9 and 10 inflows were 2,516, 2,416 and 2,357 cfs respectively, which is 1.39 feet below spillway. If the inflow stays the same, Steger said the reservoir will begin spilling in roughly five days…

This morning’s [July 12] reservoir elevation was 9015.82 feet, which is 1.18 feet below the spillway lip and 0.21 feet higher than yesterday morning. Yesterday’s inflow was 2224 cfs, down from 2357 cfs on Sunday. Yesterday’s outflow was about 1890 cfs.

From The Greeley Tribune (Eric Brown):

A lack of rain and snow in the fall and extending through the spring left agriculture producers sweating it out for the first seven months after they had planted their winter wheat. But because the rain eventually came in May, “just in the nick of time,” local farmers are now rejoicing over the average crop that’s expected to be harvested starting this week. “Compared to what we were looking at, the crop we have now is really amazing,” Keith DeVoe, general manager at the Roggen Farmers Elevator, said. “It’s kind of a miracle.”
