D-2. Lake Owasso Water Quality Update <br />Scott Sobiech, Barr Engineering reported that ten sediment cores were collected at <br />a 10-centimeter depth, evenly distributed throughout Lake Owasso. The analysis <br />showed phosphorous in the sediment mostly in the upper three to four centimeters <br />of water. However, the level of phosphorous is lower than expected. It was <br />surprising to find a significant amount of organic material bound with the <br />phosphorous that is coming from algae. The report will include analyses of <br />different scenarios, BMPs and climatic conditions. <br />Stark expressed his concern about collecting samples only one year and asked if <br />samples would be collected next year. Mr. Maloney agreed that with phosphorous <br />in the core samples, it would be good to know if there is a difference from one <br />year to the next. <br />Mr. Sobiech stated that if more data is needed, more samples will be taken. He <br />hopes to have a draft report on the organic material by the January Board meeting. <br />It was the consensus of the Board for Mr. Sobiech to send the letter to Mark right <br />away. It will also be included in the draft report. <br />Eckman emphasized the need to keep the promise to residents who participated in <br />the survey of informing them of results. Mr. Maloney suggested that a summary <br />be put on the website with the opportunity for homeowners and anyone who uses <br />the lake to give input. <br />Mogg requested that the Lake Owasso study include all inlets to the lake with <br />references in the report that identifies each inlet on the survey so it can be <br />determined which are not incorporated into the study. <br />Mr. Sobiech stated that the majority of inlet pipes come from sump pumps. Mr. <br />Maloney noted that some of those sump pumps may not be in compliance with <br />City regulations. He agreed that all inlets need to be identified in the study, as the <br />Board needs to know which pipes are public to be addressed. <br />D-3. Update on Ramsey/Washington <br />Mr. Aichinger reported that two press releases were sent out from Shoreview for <br />the Lake Owasso study. <br />D-4. Ramsey Conservation District (RCD) Discussion <br />Mr. Tom Petersen, District Administrator and Mr. Ryan Johnson, NATURE <br />Specialist presented an overview of the function of RCD with a request for <br />
