necessary to achieve Lake Olson's goals, The link between the three lakes necessitates consideration of the effect of upstream lakes on the water quality of downstream lakes when establishing their goals. VBWD will monitor the water quality of Lake Olson and consider monitoring the water quality of Olson Lake Estates pond. VBWD's current water quality monitoring program calls for Lake Olson to be sampled every three years. Depending on which outlet option is chosen for outletting the Olson Lake Estates pond, VBWD will consider whether to sample Olson Lake Estates pond and Lake Olson annually for the first three years after project completion to determine if there are noticeable impacts to the water quality of Lake Olson. Depending on the monitoring results, VBWD may then return to sampling Lake Olson every three years. VBWD will also consider authorizing a study to analyze the effectiveness of placing treatments at critical points to maximize the long-range water quality goals of all lakes in the Tri-Lakes system. Examples of this concept may include treatment of the Long Lake outflow entering Lake DeMontreville or construction of water quality treatment facilities at various points upstream of the Tri-Lakes. 4.2.9 Lake Jane Water Management Plan 4.2.9.1 Location and General Description Lake Jane (DNR #82-104P) is located in subwatershed JAN1, in the northwest corner of the City of Lake Elmo, southeast of Lakes Olson and DeMontreville. The lake has a surface I area of about 160 acres and a maximum depth of 35 feet. The Lake Jane tributary watershed is 921 acres, which includes Hedges Bog and Hedges Pond. The tributary watershed is 976 acres if Deer Pond and Crombie Pond are included. ( Under flooding conditions, water from Lake Olson (4,352 acres or 3,866 acres, excluding Olson Lake Estates) will flow to Lake Jane. Therefore, the total Lake Jane tributary area is 5,328 acres or 4,842 acres, excluding Olson Lake Estates. Most of the Lake Jane watershed is developed. Some developable land in the watershed is located east of Jane Road North, north of 45th Street North and just south of T.H. 36. ' 4.2.9.2 Drainage Patterns and Stormwater Issues A 459-acre portion of the tributary area is located between Lake Jane and T.H. 36 (subwatersheds JAN7 - JAN10, JAN13, and JAN14). Land use in the area includes the Fox Fire Estates, Springbom's Green Acres, and Lake Jane Estates developments, along with undeveloped land just south of T.H. 36. After overflowing a series of water bodies and wetlands, water would flow south, eventually reaching a pond north of Jane Road North, west of the extension of Jamaca Avenue North. This pond overflows Jane Road North at Elevation 940.2. At the time of the Fox Fire Estates and Springbom's Green Acres developments, a pipe outlet was proposed from this pond to Lake Jane. However, VBWD did not allow the outlet to be constructed, so the road overflow is the pond outlet. During design of Project 1007, this area was found to be tributary to Lake Jane, assuming existing outlet conditions. However, no discharge from the area has been observed, which indicates that seepage from the ponds has been enough to dissipate the runoff from the watershed. If overflow from the watershed were to occur, it could have an impact on the water quality of Lake Jane. A 1978 plan prepared for the City of Lake Elmo proposed a storm drainage system for the area. Part of the plan included a lift station to carry water from the pond north of Jane Road North to the large DNR-protected wetland (#82-100W) located southwest of 55th Avenue ( 23\82\045\SEC4.RPT\KMH 29 DRAFT: June 23, 1994
