A new staff person, Kristine Lampert, was <br />hired in April 2007 and has invested time and energy into elevating the monitoring program's objectives and quality. A <br />full time intern worked in the field to collect more data as well as on entering data into the MPCA's STORET <br />database. A light -weight canoe was bought to allow for VLAWMO staff to get out on the water bodies in order to <br />measure dissolved oxygen (DO) and water temperature using a DO meter given to VLAWMO by SPRWS. A flow <br />meter was also acquired from SPRWS but due to the drought of 2007, there was no opportunity to try out the meter. <br />Two flumes along Lambert Creek were replaced this winter and new gauges were installed with the flumes which will <br />aid in recording accurate flow for the stream. Additionally, VLAWMO staff was trained in the calibration of lake level <br />gauges and will assist the MN Department of Natural Resources (DNR) by calibrating the gauges within VLAWMO <br />for future years. <br />
