2012-08-02 "Lake Dalwigk Improvements Encourage More South Vallejo Wildlife"

 from Vallejo News" published by the City of Vallejo:
The Vallejo Sanitation and Flood Control District is currently installing a new low-flow outlet and modifying channels and wetland areas in Lake Dalwigk. Started in late June, this project will increase the quality and diversity of wildlife habitats as well as enable better access for annual maintenance activities.  The project will enhance the South Vallejo environment and provide more birdwatching opportunities for users of Lake Dalwigk Park.
Located adjacent to Curtola Parkway and Lemon Street in South Vallejo, Lake Dalwigk provides storm water storage, flood control and wildlife habitat. The facility serves as a detention basin for the water flowing through storm drains and open channels in the surrounding neighborhoods. Storm water collected in the lake is pumped out to the Mare Island Strait by the pump station at the corner of Stewart Street and Solano Avenue.
A new channel, approximately two feet deep with a varied width of 50 to 150 feet, will be created through the eastern and central portion of the lake to accommodate a mixture of wetland and upland habitat. Additionally, a new low-flow outlet will prevent year-round pooling in the lake, except in designated wildlife habitat areas.
Originally part of the Bay, over time development along Sonoma Boulevard and fill cut the inlet off and created the lake. The lake was expanded in the 1970s to provide flood protection to the community.
