KEARNEY STORMWATER MANAGEMENT
MCM #3 Illicit Discharge Detection and Elimination
KEARNEY STORMWATER MANAGEMENT PLAN
Cloudy winter days make the snow melt faster, says a study from the University of Utah. Snow is designed to stay cold in three ways: by deflecting the sun’s heat with it’s bright white color and crystalline structure, the bright white reflecting heat back at night, and sublimation, evaporating from snow to vapor, similar to the way sweat evaporates from our skin to keep us cool.
Cloudy humid days, however prevents snow from deflecting, reflecting and sublimating warming the snow. That is why a few humid days with temperatures hovering around the freezing point create large melt events and even minor flooding.
Do your own experiment by watching snow that remains in shadows even on warm sunny days. Then watch what happens to that same snow during gray days and nights — quickly, though, before it’s all gone.

Researchers, led by Estelle Chaussard from the University of Buffalo, link ground water recovery in Santa Clara Valley California to the state’s newly instated water conservation efforts—policies that diverted surface water to refill aquifers
In 2013, interferometric synthetic aperture radar (InSARa) measured a 2-centimeter decrease in ground-level elevation, followed by another 3 centimeters in 2014. The research team estimates a groundwater loss of about a tenth of a cubic kilometer caused the ground to shrink or lower.
Ground surfaces began to expand and rise in September 2015, rising nearly 2 centimeters over the next two years and were at pre-study levels by the end of 2016. This reflects the same time surface water diversion policy went into effect.
Falling leaves signal the official arrival of Autumn. Put leaves to good use as insulating mulch in a garden bed, make them into compost, or shred them across the lawn as a natural fertilizer. Left to lie in gutters, leaves quickly clog storm drains leading to flooding in a Fall storm and nutrient pollution as the leaves degrade in the storm sewer. Pile ’em up and enjoy the benefits of leaves next spring!
