May 2019 Streamflow Forecast

Streamflow estimates as of May 1, 2019 (Fig. 1) reflect the precipation patterns observed over winter and early spring (Fig. 2). This highlights the extent to which UT, NV – and portions of CO and CA – saw much above-average precipitation during this period. This also reveals one of the reasons concerns about Lake Mead associated shortage declarations for this year have waned in recent months (although long-term management challenges remain).
