CHAPTER 3 PROTECTION OPEN SPACE 45 <br /> • h. Mineral Lands <br /> i. Lands Containing Unique or Endangered Plants and Animals <br /> WATER BASINS AND WATER COURSES <br /> Water basins are lakes and ponds entirely surrounded by land. Watercourses are <br /> channels for year-round or intermittent flow including rivers, streams, and creeks. <br /> Both water basins and watercourses provide aquatic habitat, recreational opportunities, <br /> and aesthetic values. They are essential ingredients in the hydrologic cycle for the storage <br /> and movement of water. This is particularly important in New Brighton because the water <br /> basins and watercourses are essential parts of the City's storm sewer system. Four segments <br /> of the system flow through New Brighton. (See Map 3.) County Ditch No. 2 drains the <br /> area from Roseville through Jones Lake, Hansen Park, Pike Lake, and Long Lake. County <br /> Ditch No. 3 drains the area from Columbia Heights (Silver Lake), to Poplar Lake, Jones <br /> Lake into Ditch 2. A third system drains the easterly areas of Round Lake, Josephine Lake, <br /> Johanna, Owasso, and other ponds, crossing under I-694 and I-35W from Old Highway 8 <br /> into Long Lake. The fourth system collects from the north through Rice Creek, draining <br /> into Long Lake. All systems then drain to the west via Rice Creek to the Mississippi River. <br /> New Brighton is part of the Rice Creek Watershed District, a special purpose district <br /> • organized to deal with water resources and related land use problems within the drainage <br /> area of Rice Creek. The district covers an area of about 200 square miles surrounding Rice <br /> Creek from its source at Clear Lake in Washington County. <br />
