Radar-rainfall reconstruction of the Saguache Creek flash flood of July 25, 1999
Radar-rainfall reconstruction of the Saguache Creek flash flood of July 25, 1999
On July 25th 1999 a portion of the Saguache Creek basin located northwest of the town of Saguache Colorado experienced a localized yet intense period of rainfall. Heavy rainfall flooded Saguache Creek and its tributaries both north and south of Highway 114. The resultant flash flooding washed out roads and bridges along with the inundation of crop and rangeland located in and along these flooded tributaries. The purpose of this report is to document the meteorological causes, reconstruct the estimated spatial coverage, temporal duration, and rainfall depth of the thunderstorm complex that produced the flash flood., "June 2001.", Description based on online resource; title from PDF cover (viewed November 2013), PB PDA 00000000023

Reclamation feasibility report, Henson Creek watershed
Reclamation feasibility report, Henson Creek watershed
This report is intended to be a guidance document for use by the Lake Fork of the Gunnison Watershed Group (LFWG) in prioritizing and planning water quality reclamation projects at Mine sites in Henson Creek above the confluence with the Lake Fork of the Gunnison River. Investigation of the water quality of Henson Creek was initiated as part of the effort to improve the water quality in the Lake Fork of the Gunnison above Lake City. Henson Creek was targeted because previous investigations had shown that Palmetto Gulch was impacted by past mining, resulting in listing on the Clean Water Act 303(d) list of impaired waters for zinc and cadmium. In addition there was visual evidence of impairment in other portions of the Henson Creek Watershed., "Special thanks to the Lake Fork Watershed stakeholders.", "June 2006.", Includes bibliographical references (p. 71), Description based on online resource; title from PDF title page; (viewed November 2013)

Recommended buffer zones and seasonal restrictions for Colorado raptors
Recommended buffer zones and seasonal restrictions for Colorado raptors
Tolerance limits to disturbance vary among as well as within raptor species. The term "disturbance" is ambiguous and experts disagree on what actually constitutes a disturbance. Although there are exceptions, the buffer areas and seasonal restrictions suggested here reflect an informed opinion that if implemented, should assure that the majority of individuals within a species will continue to occupy the area. Additional factors, such as intervening terrain, vegetation screens, and the cumulative impacts of activities should be considered, Includes bibliographic references (p. 5-7), Description based on online resource; title from PDF caption (viewed July 2014)
