Eckman moved to fund the education program, Minnesota Water -Let's Keep It Clean" in the amount of $2,000, for 2008. DeZellar seconded. Ayes - 3 Nays - 1 (Mogg). D-2. Lake Owasso Water Quality Update Scott Sobiech, Barr Engineering reported that ten sediment cores were collected at a 10-centimeter depth, evenly distributed throughout Lake Owasso. The analysis showed phosphorous in the sediment mostly in the upper three to four centimeters of water. However, the level of phosphorous is lower than expected. It was surprising to find a significant amount of organic material bound with the phosphorous that is coming from algae. The report. will include analyses of different scenarios, BMPs and climatic conditions. Stark expressed his concern about collecting samples only one year and asked if samples would be collected next year. Mr. Maloney agreed. that with phosphorous in the core samples, it would be good to know if there is a difference from one year to the next. Mr. Sobiech stated that if more data is needed, more samples will be taken. He hopes to have a draft report on the organic material by the January Board meeting. It was the consensus of the Board for Mr. Sobiech to send the letter to Mark right away. It will also be included in the draft report. Eckman emphasized the need to keep the promise to residents who participated in the survey of informing them of results. Mr. Maloney suggested that a summary be put on the website with the opportunity for homeowners and anyone who uses the lake to give input. Mogg requested that the Lake Owasso study include all. inlets to the lake with references in the report that identifies each inlet on the survey so it can be determined which are not incorporated into the study. Mr. Sobiech stated that the majority of inlet pipes come from sump pumps. Mr. Maloney noted that same of those sump pumps may not be in compliance with City regulations. He agreed that all inlets need to be identified in the study, as the Board needs to know which pipes are public to be addressed. D-3. Update on Ramsey/Washington Mr. Aichinger reported that two press releases were sent out from Shoreview for the Lake Owasso study.
