She writes about some very specific forecasting challenges that she and her colleagues are faced with on a daily basis. Introduction Devils Lake water levels have risen over 10 meters in the past 22 years. Due to natural variability in winter precipitation, the water level may further rise in spring as a result of melting of the snowpack in the lake’s basin. Such a…
