Review of conditions in Snake River basin over the 2016-17 Water Year.
How patterns in snowmelt and streamflow are related, anecdotal “Rules of Thumb” and statistical tools for measuring the amount of snow, when it melts and how quickly it melts in different parts of Idaho.
Explains what is NIDIS, what is a drought early warning, what is a Drought Early Warning System (DEWS), background of Pacific NW DEWS.
Current drought/climate conditions in the Pacific Northwest: precipitation, soil moisture, temperature.
Overview of 2015-16 cloud season results, Payette Target-Control, Basin-wide Target-Control results, Weather Research Forecast (WRF) modeling results, WRF model example, 2016-17 project overview, SNOWIE: Seeded and Natural Orographic Wintertime clouds — the Idaho Experiment.
Water Year 2016-17 conditions in the Payette and Owyhee River drainages.
Discussion of the relationship between drought and wildfire. Key message include:
Drought is now affecting all ecosystems, could get worse Changes most obvious in the West, impacts in eastern forests through morbidity, slow decline Impacts both immediate and long-lasting Plant stress, drought-tolerant species Habitat shifts Some invasive species can benefit Reduced carbon storage and water supplies Manage to increase resiliency and resistance
Summarizes conditions in Idaho over the past year including snow pack, SPEI, temperature, precipitation, drought, reservoir levels, lake levels.
A presentation at the Inland Pacific Northwest DEWS Water Year Outlook meeting, November 10, 2016.
Discussion of evaporative demand (how “thirsty” the atmosphere is), how to calculate the evaporative demand index, and why it matters as a leading indicator of drought.
2016 fire season summary: Pioneer Fire background, Burned Area Emergency Response (BAER), fire effects on watersheds, Forest Service response, anticipated watershed effects.
