Reed Canyon Enhancement Strategy
Upper Lake Management Zone
Location: The Upper Lake extends for the headwater headwater springs in the northeast and southeast end of the site, down to the sanitary sewer line that crosses the lake. The area is approximately 463,000 sq ft of upland with an additional 180,000 sq ft of open water / emergent marsh.
Condition: This area is dominated by reed canarygrass, nightshade and morning glory in the wetter portions of the site. Clematis, blackberry, and ivy dominate the upland areas. The upper lake will be the greatest challenge in invasive species management, and will require a variety of approaches. However the area is most critical, since wind and water will spread exotic seeds down canyon. The eastern and northern edge of the area is in need of buffering / screening from neighboring residents. The trail that goes around this area is in need of upgrading to elevated boardwalks to reduce pedestrian impact to water quality and risk of injury by those using the trail. This is the most isolated portion of the site, offering increased opportunity for the visitor to experience wildlife and solitude.
Vision: The spring fed portions of the site could easily support, an emergent marsh system with snags and basking logs in the open water areas. Along the edges of the marsh and in defined spring channels, a riparian edge plant community could be established. The uplands have the opportunity to support a headwater forest community, with understory and climbing vine invasive species control. There are also a few wetter areas that would support a forested wetland community.
