53 Stream P Concentrations Standard: mg/l for most sites, 0.10 mg/l for Fulton

54 WY2017 Year in Review Above average precipitation (~42 through Sep 1, +20%) Wet Fall, mid-summer Below average snowfall (~44, -14%) ~60,000 lb. P delivered to Lake Mendota among the 4 major tributaries (preliminary!) Lake Mendota experienced a HAB on ~6/16/17 Rainfall/runoff on 6/12 may have helped to trigger Water temp, wind, and sunlight also factors TP concentrations at streams tributary to Lake Mendota continue to be well above the mg/l standard.
