The Ozaukee County Planning and Parks Department has established a robust water quality sampling and monitoring program on the Little Menomonee River and Creek, Mole Creek, and Ulao/Kaul Creek through grant funding beginning in 2016. A series of discrete water quality sampling events and continuous water quality monitoring using stationed units is providing data necessary to establish a baseline and provides insight into water quality trends associated with stream and habitat restoration pre- and post-construction, potentially validating the numerous benefits of the Department’s restoration projects.
Discrete water quality samples are collected and analyzed for chloride, E. coli, orthophosphate (dissolved reactive phosphorus), total phosphorus chloride and total suspended solids (TSS) by the Wisconsin SLOH approximately every 30 days from May – October. Additional quantitative abiotic parameters are measured at time of water sampling using a handheld instrument, including: water temperature, pH, conductivity, total dissolved solids (TDS), dissolved oxygen concentration and percent saturation, turbidity, salinity, atmospheric pressure, air temperature, wet and bankfull width of the stream, and water depth and velocity (at one foot increments across the stream). Visual observations regarding water clarity, condition of riparian habitat, and presence of animal species are also noted. Deployable continuous water quality monitoring units are deployed seasonally (May – October) and are designed to measure water temperature, water depth, dissolved oxygen concentration, pH, and conductivity and programmed to record readings every 30 minutes.
