OUR GEM: Hygiene, it’s not just for people…

Author: Ben Scofield, Coeur d’Alene Tribe Water Resource Specialist In all seriousness watercraft hygiene is an important subject in these days of increasing pressure upon our shared waterways. The Idaho State Department of Agriculture which operates watercraft inspections stations throughout the state recorded about 125,416 inspections in 2025. Each of these watercraft trips represent an opportunity for an aquatic invasive species (AIS) to jump from an infested waterbody to an un-infested one. With the detection of quagga mussel in the…

OUR GEM: Understanding Aquifer Protection Through a Practitioner’s Lens

Author, Karla Freeman, Kootenai-Shoshone Soil and Water Conservation District Manager As communities across the Inland Northwest face increasing drought, population growth, and changing hydrologic conditions, discussions about water supply and water quality are becoming more frequent—and more technical. To help ground these discussions in local context, it is useful to hear from practitioners who work directly with land, water, and agricultural systems and who regularly engage with scientists, regulators, and landowners. One such practitioner is Laurin Scarcello. Scarcello has recently…

OUR GEM: From Drain to River, How a Local Treatment Plant Is Improving Water Quality

By Pilar Deniston, Coeur d’Alene Lake ARPA Project Coordinator for Idaho DEQ When water from your home, whether from the toilet, sinks, or shower goes down the drain, it travels through a network of pipes to a wastewater treatment facility (unless you’re on a private septic system). There, it undergoes a series of treatment steps to become clean enough to return safely to the natural environment. The process begins with pretreatment, where large debris like sticks and plastic, along with…

OUR GEM: Taking Public Comments Regarding Wetland Protection Rule Changes

by Sharon Bosley, Executive Director for the Basin Environmental Improvement Project Commission The Clean Water Act (CWA) was created to protect our water resources by regulating discharge of pollutants into the waters of the United States. Its goal is to help ensure all waters are swimmable, fishable and drinkable. The purpose of defining the Waters of the United States (WOTUS) is to determine which waterways are protected under the CWA. The definition determines which waters require permits for activities that…

OUR GEM: Local Students Find Excitement with Hands-On Science

by Woody Wood, IWRRI Education and Outreach Coordinator It’s a cool fall morning, and I’m standing at the intersection of Burnt Cabin and Ohio Match Roads waiting for a bus load of Venture Academy students to arrive. While I wait here with my colleagues, travelers stop and ask why we have dozens of pairs of rubber boots lined up next to our vehicles. We tell them about the incoming students and the work they are about to do, and they…
