HYDROLOGY MONITORING <br />A. Methodology and Site Selection <br />Nine hydrology monitoring wells were installed throughout the wetland, seven being spread <br />throughout the site, one logger was installed within the ditch, and one reference data logger was <br />installed in a wetland to west of the site on July 6, 2022 as shown in Attachment C. Wells were <br />installed per the BWSR guidance Hydrologic Monitoring of Wetlands. One-inch and one-and-half- <br />inch diameter wells were installed that consisted of a slotted well screen positioned at least 2 feet <br />below the ground level and an unslotted riser that rose above the ground surface. The total well <br />depths ranged from 2-3 feet. Within each well, a data logger was used to measure pressure <br />(PSI), temperature (C), and depth of water (feet above the sensor). Each measurement was <br />logged once per hour. Well data was downloaded once mid-season and again at the end of the <br />growing season (October 4, 2022). <br /> <br />B. Results <br />Graphs showing the hydrology monitoring results are included in Attachment D. The data logger <br />in well 6 malfunctioned and the data was lost. <br /> <br />Table 2.
