Onsite Comments

Water was slightly cloudy with a green tint, slack water spots had a thin, white, bubbly film on the surface, base flow, dissolved oxygen levels between 7-10ppm, no ammonia hits, dead fish had distended bellies, some were fuzzy, most lacked color (white), fish on bottom had guts trailing, most fish present above and below 215th St. bridge or in areas where little overhead vegetation was present (reed canary and rice cut grass, nettles, or dense tree cover). A helicopter was aerial spraying bean fields during investigation and a fill tanker was in a field nearby. An adjacent landowner called the kill in and said he noticed it the afternoon of 7/30/2019. Suspected over-spray from aerial pesticide application activity of bean fields in area.

Report named it UT Flood Creek, but GIS and maps indicate it's UT Beaver Creek.
