BSU Team Develop New Approaches to Estimating Contributions to Streamflow
Boise State University faculty Anna Bergstrom and her team investigated rain and snowmelt contributions to streamflow in the Mores Creek Watershed spanning the rain-snow transition zone in southwestern Idaho. Researchers commonly use naturally occurring water isotopes to track water sources allowing for the quantification of if streams are sourced from rain or snow. By developing new approaches to define rain and snow isotopic signatures, Bergstrom and team found that streamflow contribution estimates can vary by up to 20%, depending on…

The Idaho Governor’s Office of Species Conservation (OSC) is dedicated to planning, coordinating and implementing the State’s actions to preserve, protect and restore species listed as candidate, threatened or endangered under the federal Endangered Species Act (ESA). This work is done in coordination with the State’s natural resource agencies and with input from…
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: Restoration Project Turns Back the Clock at Hepton Lake
By Angelo Vitale, Fisheries Division Manager Last year, the Coeur d’Alene Tribe wrapped up construction work on one of its most ambitious projects to date and something that has been in the works for more than a decade. The Snyihms he mulshu’lmkhw (Swimmer’s Landing among the Cottonwoods) Project is located adjacent to the lower St. Joe River a few miles west of St. Maries, Idaho. During the pre-settlement era, the site was a floodplain marsh and wet meadow and was…
OUR GEM: k’wne’ ‘ulchiyark’wmtsut – Fisheries Restoration Connecting Two Restored Reaches
By Bruce Kinkead, Fisheries Biologist, Coeur d’Alene Tribe The Hangman Creek Fisheries Restoration Project began in 2002 and is funded by Bonneville Power Administration under the Fish Substitution Policy to compensate for lost salmon harvesting. Early research found the limiting factors to be lack of connection between channel and floodplain, lack of large woody debris (LWD), excess fine sediments, and high stream temperatures associated with a lack of tree canopy. Initial work on Hangman Creek below the Sanders townsite began…
BSU Student Analyses Wildfire impacts on Snowpack
Master’s student Mason Bull recently won the Boise State University three-minute thesis competition and placed third at the state competition. Mason was partially funded by a research initiation grant from the Idaho Space Grant Consortium (Idaho NASA EPSCoR). His research is using the Landsat record to classify landscape composition and quantify landcover and vegetation change in one watershed in the Kenai Mountains of south-central Alaska and the Sawtooth Mountains of southwest Idaho. He is finding that places in Idaho that…
