The Big Burn of 1910 Ranger

OUR GEM Ashes in the Current: The Hidden Hydrologic Legacy of the 1910 Fire

By Mark Getscher, hydrogeologist for the Coeur d’Alene Tribe More than a century after “The Big Burn” of 1910 scorched over three million acres across northern Idaho and western Montana, its legacy continues to flow through the streams and rivers of the Coeur d’Alene Basin. While most remember the fire for its devastation and heroism, far fewer realize its silent and lingering impact on water quality. High-intensity wildfires combust vegetation and organic soil layers, converting them into ash. This ash is…

OUR GEM: Water Smart

by William Rettig, Water Efficiency Specialist for the City of Spokane North Idaho summers are made for being outside, whether that’s cooling off in Coeur d’Alene Lake, hiking in the mountains, or tending to the yard, it’s impossible to spend too much time outdoors. But, when it comes to watering your lawn, more isn’t always better. Most people water too much, gaining little benefit for their grass and skyrocketing their utility bills. On average, lawns only need one inch of…

OUR GEM: Hold Your Ground! A case for good construction site planning

OUR GEM: Hold Your Ground! A case for good construction site planning Erosion control is a critical aspect of responsible site development, especially in areas with steep terrain and heavy precipitation, which is often the case in North Idaho. This case study highlights the challenges faced during the development of a hillside property near Hayden Lake and the efforts to address consequences of inadequate initial planning. Background In 2021, two properties on the hillside above Hayden Lake underwent development for…

U of I Researchers Design Biochar-based Water Treatment System

A University of Idaho team, led by Professor Amin Mirkouei and supported by two recently graduated doctorate students, Rance Bare and Ethan Struhs, collaborated with the USDA Agricultural Research Service (Ken Overturf), U of I Aquaculture Research Institute (Brian Small) and the National High Magnetic Field Laboratory (Martha Chacón-Patiño, Amy Mckenna and Huan Chen) to design and custom-build an economical and sustainable water treatment system. This system was specifically developed to remove micronutrients, primarily phosphorus and nitrogen, from the wastewater…
