4.2.6.3 Water Quality Data, DNR Data. and Public Use <br />Current active use of the pond is limited to the few property owners on the pond; passive <br />use is available to trail users who pass by the pond. No water quality or fisheries data is <br />available for the pond. The DNR has no management plans for the pond. <br />4.2.6.4 VBWD Water Quality Management Goals <br />VBWD will work with the DNR to monitor the impacts of the Capaul's Pond overflows <br />on the pond in DeMontreville Highlands 3rd Addition. If overflows negatively impact the <br />pond, VBWD will consider preparing a feasibility study to determine whether water should <br />continue to be directed to the pond in DeMontreville Highlands 3rd, or if the water should be <br />directed to the pond in Pine Plantation, eventually reaching Long Lake. Then, the need for an <br />outlet from either of the ponds will need to be determined. If an outlet is needed, VBWD will: <br />Determine the impact of the additional water on Long Lake and/or Lake <br />DeMontreville. <br />2. Investigate the possibility of acquiring the flood -prone property on Capaul's Pond <br />and possibly raising the runout elevation of Capaul's Pond. <br />3. Prepare cost estimates for all options. <br />VBWD will consider preparing hydrologic and nutrient budgets for Capaul's Pond to <br />assist in determining the impact of the additional water on the water quality of Long Lake or <br />Lake DeMontreville. Prior to preparing the budgets, VBWD will collect water quality samples <br />from Capaul's Pond to determine its existing water quality. VBWD will consider preparing a <br />bathymetric map at the time water quality samples are collected. <br />4=—L—ake e on reville Water danagement�Plan <br />4.2.7.1 Location and General Description <br />Lake DeMontreville (DNR #82-101P) is located in subwatershed DEM1, in the northwest <br />corner of the City of Lake Elmo. Lake DeMontreville is about 150 acres in area and has a <br />maximum depth of about 29 feet. The Lake DeMontreville tributary watershed is 1,220 acres <br />and is comprised of subwatersheds DEMI - DEM6, DEM8 - DEM14, DEM16, DEM18 and <br />DEM19. The tributary area includes the Capaul's Pond outflow which flows to the pond in <br />DeMontreville Highlands 3rd Addition (in DEM2). Since the Long Lake outlet stream enters { <br />the north shore of Lake DeMontreville, the total tributary area, including the Long Lake <br />watershed (2,357 acres), is 3,577 acres. Figure 2-3 shows the tributary area. Another stream <br />enters the north shore of Lake DeMontreville, approximately 2,000 feet east of the Long Lake € <br />outlet stream. This stream carries water from the tributary watershed northeast of the lake, <br />including 353 acres in Grant Township. Less than half of the watershed. in Grant Township is <br />currently developed and it contains many wetlands. The land use plan calls for the area in <br />Grant Township to be developed into five -acre lots. Because of the proposed future land use <br />and number of wetlands, the impact of future development in Grant Township on Lake <br />DeMontreville water quality is expected to be minimal. This is especially true since the major <br />contributor of nutrients to Lake DeMontreville is the outflow from Long Lake. <br />The Lake DeMontreville shoreline is in private ownership and largely developed. <br />However, most of the eastern shoreline of Lake DeMontreville is owned by religious groups; <br />which developed the properties as retreat centers and monasteries.
