Ross Lord Park (June 7, 2026 at 3 pm) near the bridge by the washrooms within the reservoir area of the West Don River. The site is an urban park environment with surrounding residential land use and mixed bank vegetation including trees, shrubs, and grass. Weather conditions were sunny and warm, with an air temperature of 28 °C.\r\n\r\nWater appeared clear during observation, with the bottom visible at shallow depth near the sampling area. Estimated water depth was approximately 0.4 m. The Secchi depth was not formally measured but clarity was noted as good.\r\n\r\nPhysicochemical results indicated generally healthy water conditions. Dissolved oxygen was high at 12 mg/L, suggesting well-oxygenated water. pH was 8.4, slightly alkaline but within acceptable range for freshwater systems. Chlorine was not detected (0), as expected for a natural water body. Hardness was 170 ppm (moderately hard), alkalinity was 240 ppm (high buffering capacity), and conductivity measured 281 µS/cm, all consistent with mineral-rich urban freshwater conditions. Water temperature was 21 °C, typical for summer conditions.\r\n\r\nOverall, the site shows stable and healthy water quality conditions, with no immediate concerns based on the parameters measured.","checked":"qc_complete","qa_notes":null,"qa_admin_notes":"","qa_admin_notes_author_id":null,"qa_admin_notes_updated_at":null,"tested_parameters":["current_weather","current_weather_description","previous_weather","secchi_depth","water_depth","ph","oxygen","chlorine","hardness","alkalinity","conductivity","air_temperature","water_temperature"],"photos":["https://d27925nfpi4rwv.cloudfront.net/rails/active_storage/representations/proxy/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBBMjVMQXc9PSIsImV4cCI6IjIwMjYtMDctMDFUMDE6MjU6MzcuODk1WiIsInB1ciI6ImJsb2JfaWQifX0=--41b7bbf4723a81895458f9f978fe4c842e687b41/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaDdCem9MWm05eWJXRjBTU0lJYW5CbkJqb0dSVlE2RTNKbGMybDZaVjkwYjE5bWFXeHNXd2RwQXBBQmFRS1FBUT09IiwiZXhwIjpudWxsLCJwdXIiOiJ2YXJpYXRpb24ifX0=--137cfa046b685d2c2c17f66eaa6c647bd283e601/DSC_0262.jpg"],"permalink":"https://data.waterrangers.com/observations/212155","readings":[{"id":"6d5ea8c7-79a3-4fa4-afee-f1d0d060a687","created_at":"2026-06-17T13:25:55.718Z","updated_at":"2026-06-17T13:25:55.718Z","parameter":"current_weather","unit":"nil","value":"sunny","equipment":"community_scientist_interpretation","equipment_limit":null},{"id":"52aa511f-bcca-4dc8-99bc-d891698a8404","created_at":"2026-06-17T13:25:55.725Z","updated_at":"2026-06-17T13:25:55.725Z","parameter":"current_weather_description","unit":"nil","value":"Sunny (clear sky conditions ☀️)","equipment":"community_scientist_interpretation","equipment_limit":null},{"id":"f3cf19ef-3fdc-4d7c-947b-8107780ebd5e","created_at":"2026-06-17T13:25:55.731Z","updated_at":"2026-06-17T13:25:55.731Z","parameter":"previous_weather","unit":"nil","value":"sunny","equipment":"community_scientist_interpretation","equipment_limit":null},{"id":"f1c6413d-960f-44c5-b295-0675516ce8bd","created_at":"2026-06-17T13:25:55.738Z","updated_at":"2026-06-17T13:25:55.738Z","parameter":"previous_weather","unit":"nil","value":"cloudy","equipment":"community_scientist_interpretation","equipment_limit":null},{"id":"00200a85-934c-4647-a9fd-da296c8ed228","created_at":"2026-06-17T13:25:55.744Z","updated_at":"2026-06-17T13:25:55.744Z","parameter":"secchi_depth","unit":"m","value":"bottom_visible","equipment":"secchi_disk_20cm","equipment_limit":null},{"id":"17bab217-8f10-4e85-945e-8852261b03ff","created_at":"2026-06-17T13:25:55.751Z","updated_at":"2026-06-17T13:25:55.751Z","parameter":"water_depth","unit":"m","value":"0.4","equipment":"secchi_disk_20cm","equipment_limit":null},{"id":"125fecf9-1879-482b-af63-88d51cb9d441","created_at":"2026-06-17T13:25:55.757Z","updated_at":"2026-06-17T13:25:55.757Z","parameter":"ph","unit":"std_units","value":"8.4","equipment":"water_rangers_freshwater_teststrips_ph","equipment_limit":">="},{"id":"f1c8b0a6-152d-44e3-8e31-e7816282c8b0","created_at":"2026-06-17T13:25:55.763Z","updated_at":"2026-06-17T13:25:55.763Z","parameter":"oxygen","unit":"mg_l","value":"12","equipment":"chemetrics_dissolved_oxygen_mg_l","equipment_limit":">="},{"id":"64ec76d5-0117-4f32-bca5-0f3007178aa0","created_at":"2026-06-17T13:25:55.770Z","updated_at":"2026-06-17T13:25:55.770Z","parameter":"chlorine","unit":"ppm","value":"0","equipment":"water_rangers_freshwater_teststrips_chlorine","equipment_limit":"<="},{"id":"2460860e-6820-4ebb-ac0f-1fc0e3020ba1","created_at":"2026-06-17T13:25:55.775Z","updated_at":"2026-06-17T13:25:55.775Z","parameter":"hardness","unit":"ppm","value":"170","equipment":"water_rangers_freshwater_teststrips_hardness","equipment_limit":null},{"id":"6a09343e-8155-4405-9df1-047adf1da977","created_at":"2026-06-17T13:25:55.782Z","updated_at":"2026-06-17T13:25:55.782Z","parameter":"alkalinity","unit":"ppm","value":"240","equipment":"water_rangers_freshwater_teststrips_alkalinity","equipment_limit":">="},{"id":"94479c2b-199b-4b12-95b0-e9eb087465be","created_at":"2026-06-17T13:25:55.788Z","updated_at":"2026-06-17T13:25:55.788Z","parameter":"conductivity","unit":"us_cm","value":"281","equipment":"water_rangers_pen_type_conductivity_meter_low_range","equipment_limit":null},{"id":"de7bcb42-6e84-46c5-b0b2-cbe06cce1e1f","created_at":"2026-06-17T13:25:55.793Z","updated_at":"2026-06-17T13:25:55.793Z","parameter":"air_temperature","unit":"deg_c","value":"28","equipment":"stream_thermometer_water_rangers","equipment_limit":null},{"id":"b89e3e24-0b82-4c90-b11d-821573d995ac","created_at":"2026-06-17T13:25:55.799Z","updated_at":"2026-06-17T13:25:55.799Z","parameter":"water_temperature","unit":"deg_c","value":"21","equipment":"water_rangers_pen_type_temperature_meter","equipment_limit":null}]}]
