approaches is not precise, as some areas combine both active management and reliance on <br /> natural passive wetland features. <br /> Wetland Restoration <br /> Seasonal marshlands will be created by a combination of approaches, including seasonal <br /> flooding (by pumping) into the bottom of South Tracy Lake during early fall, constructing <br /> dikes across flood basins, swales, and gently contouring landscapes to collect local <br /> surface runoff. Discontinuation of cattle grazing will also allow for the re-establishment of <br /> seasonal marsh in this area. <br /> The main area of seasonal marsh restoration will occur in the eastern portion of South <br /> Tracy Lake. Water levels will be maintained at approximately 12 feet msl during the target <br /> waterfowl season (October 1 -January 1). During winter at maximum flood-up (January 1 <br /> - March 10), water levels will be close to 25 feet During the flood-up period, water levels <br /> will vary from the dike area, where the water levels will be deepest (2+feet), to the far <br /> eastern part of the lake, where water levels will be shallower (2 inches) (Fig. 2). Several <br /> new areas of seasonal marsh will be developed by leveling steep areas around the perimeter <br /> of the lake (see restoration map 5). <br /> I <br /> Suitability Of Soils For Wetland Development <br /> The soils in the study area are suitable for permanent and seasonal wetland enhancement. <br /> These soils have either a substantial clay content or have a hardpan or claypan that holds <br /> water sufficiently well to create wetlands. <br /> Buckeye Ranch Resource Plan (November, 1993) <br /> 186 <br />
