East Troublesome Fire -- Willow Creek Reservoir

In the fall of 2020, the East Troublesome fire burned most of the Willow Creek watershed and the land around Willow Creek Reservoir in Grand County, Colorado, leading to concerns about impacts on water quality in the reservoir. Of particular interest is phosphorus because of phosphorus-limited algal growth in the lake, high nutrient concentrations in runoff from the burned watershed, and the use of ammonium phosphate-based fire retardant in combatting the wildfire. In this study we track the impacts on water quality from the influx of nutrients in the years following the East Troublesome fire.

2020年秋季，东麻烦火灾（East Troublesome fire）烧毁了科罗拉多州格兰德县（Grand County, Colorado）Willow Creek流域的大部分区域及Willow Creek水库周边土地，引发了人们对水库水质影响的担忧。磷（phosphorus）是重点关注对象，原因在于该湖的藻类生长受磷限制、烧毁流域径流中的高营养物浓度，以及在野火扑救中使用了基于磷酸铵的阻燃剂。本研究追踪了东麻烦火灾后数年中，营养物输入对水质产生的影响。
