43:["$","title",null,{"children":"2024-25 Water quality monitoring, Upper Catherine Creek Strategic Implementation Area, Union Co. Oregon | Peter Donovan | Observable"}] 4b:T759,# 2024-25 Water quality monitoring, Upper Catherine Creek Strategic Implementation Area, Union Co. Oregon Water quality measured with YSI ProDSS sonde by Peter Donovan for the Union SWCD. (From October 2024 on, turbidity is reported from samples analyzed by a Hach turbidimeter.) Mouse over chart lines to see values. Sites were sampled in the middle part of the day, ranging from 8 am to 3 pm. The raw data from the sonde (Kor Measurement File Export) can be downloaded from the paperclip menu on upper right, as well as the condensed version (waterquality.csv) with Hach turbidimeter values (NTU) replacing sonde values (FNU) for turbidity from Oct 2024 on. From May through September 2024, the sonde's turbidity readings correlated closely with readings from the Hach turbidimeter. (See https://support.hach.com/myhach/s/article/KA-en-US-TE407-1000336?language=en_US for the different turbidity units.) ## E coli and nitrate/nitrite values Were analyzed by Bureau of Reclamation Lab in Boise. Where nitrate values were less than .01 mg/L they are reported as .01 mg/L. Where E. coli counts were <4 they are reported as 4. Where duplicate samples were taken, the values were close, and the highest values are reported in the charts. Raw data for lab results can be downloaded from paperclip menu to right as lab_results_2024_consolidated.csv. Only six sites were sampled for E coli and nitrates: the Milk Cr site, the upper and lower Mill Cr sites, and 3 sites on Little Cr: Bates Lane, Livestock show grounds, and at the LC1 diversion.
## Comments Rain events: No significant rain events preceded sampling until October 28, 2024 sampling (got two tenths 3 days before). Cattle on creek immediately upstream of sampling site lc1 (Bates Lane) at May 29, 2024 sampling. Cattle on creek immediately upstream of sampling site lc5 (LC1 diversion) at October 28, 2024 sampling.4c:Tb10,{ // Make a container in the Observable DOM to hold the map let parent =
