...THIS IS A PARTICULARLY DANGEROUS SITUATION FOR IN AND IMMEDIATELY ADJACENT TO THE FOOTHILLS, BETWEEN 5500 AND 9000 FEET, FOR BOULDER AND JEFFERSON COUNTIES ON FRIDAY... Strong west winds of 30-40 mph with gusts as high as 85 mph in the foothills of Boulder and northern Jefferson Counties will continue until early evening. Relative humidity values had dropped into the upper single digits and lower teens. Thus, the Particularly Dangerous Situation will remain in place til around 5-6 pm, with only a slow improvement thereafter as winds slowly weaken. Red Flag conditions, however, will persist through the rest of the evening as we remain in a near record warm, dry, and windy airmass along the Front Range through midnight. In fact, strong, gusty winds will persist through much of the night with only a slow improvement in humidity values. Thus, near critical Red Flag conditions will occur into early Saturday morning. While most of the Denver metro area has seen lighter winds prevail most of the day, a period of strong, gusty winds is expected to develop this evening and likely last past midnight, producing Red Flag conditions there. * AFFECTED AREA...Fire Weather Zones 238, 240, 241, 242 and 243. * TIMING...Until midnight MST tonight. * WINDS...West 15 to 25 mph with gusts up to 50 mph. * RELATIVE HUMIDITY...As low as 9 percent. * IMPACTS...Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.

Streamflow Elevation Profile
The Knife River is a tributary of the Missouri River, approximately 120 mi (193 km) long, in North Dakota in the United States.Knife is an English translation of the Native American name.It rises in west central North Dakota, in the Killdeer Mountains in Billings County. It flows east, and is joined by Spring Creek near Beulah. It joins the Missouri north of Stanton, at the Knife River Indian Villages National Historic Site.
Much of the terrain surrounding the river valley still remains in native grasslands, supporting many species of wildlife, including Whitetail Deer, Mule Deer, Coyote, Fox, Native Grouse, Pheasant, etc. Many of the small tributaries such as the Little Knife support local farms and ranches; some have been family owned for over 100 years. Some of the larger ranches include the Circle Five Ranch, Dressler Ranch, Perhus Bros. Ranch, and Greenshield Ranch.
The river consistently floods after spring melting (frequently as high as 10,000 cfs) but is two to three magnitudes lower during the summer months. The confluence of the river (near Stanton, ND) was largely blocked by sand after the Missouri River flood of 2011 but had cut a new channel by the summer of 2012.
