For those that drive up and down 7th Street between Midtown and Downtown Coeur d’Alene, you probably noticed some earthwork occurring this summer in G.O. Phippeny Park located at the corner of 7th Street and Montana Avenue. Have you wondered what on earth is going on? Well, first, let’s step back and talk about the park itself. The park was the site of the original 1910 Coeur d’Alene High School and is named after Geoffrey Otto Phippeny, who was well-known…

Hepton Lake After Wetland Restoration

OUR GEM: Restoration Project Turns Back the Clock at Hepton Lake

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…

OUR GEM: Stormwater – Here’s Your Sign!

OUR GEM: Stormwater – Here’s Your Sign! You may recall hearing or reading about the City of Coeur d’Alene and their work to reduce their stormwater discharge to Coeur d’Alene Lake and the Spokane River. Since 2018, through their Stormwater Volume Reduction Program, the City has diverted flow from seven outfalls on the river and lake for a total of 465 acres of diverted flow. That equals 13% of the City’s hard pipe/outfall area. To help share the success of…

OUR GEM: Coeur d’Alene’s Wastewater History

OUR GEM: Coeur d’Alene’s Wastewater History By Mike Anderson, City of Coeur d’Alene Wastewater Utility Director In 1939, the City of Coeur d’Alene began treating its wastewater at a brand-new facility. This plant used secondary treatment, a new level of technology just beginning to be seen in large cities, but almost unheard of in small communities like ours, with a population of barely 10,000. Motivated by a desire to be a good neighbor and environmental stewards, the City was also…

OUR GEM: Tackling Nonpoint Source Pollution in North Idaho, Protecting Coeur d’Alene Lake

OUR GEM: Tackling Nonpoint Source Pollution in North Idaho, Protecting Coeur d’Alene Lake Nonpoint source (NPS) pollution is a major environmental issue in North Idaho, particularly within the growing Coeur d’Alene Lake watershed. Unlike point source pollution, which stems from identifiable discharge points like pipes or ditches, NPS pollution is transported by diffuse sources such as rain or snowmelt. These waters pick up pollutants from urban areas, agricultural land, forests, and residential zones, eventually draining into lakes, rivers, and groundwater….
