Streams and rivers have been essential resources in human history as known of being major origins of human civilization. As urbanization occurs rapidly along with economic growth, the surrounding water environment have been substantially degraded in terms of water quality and riparian and river ecosystem health. Recent public recognition to environmental quality calls for enormous attention to restoring or retrofitting degraded stream environment. Thus, central and local government initiated ecological stream restoration projects in late 1990s. In this study, we have visited 64 select streams including streams of ecological restoration project and natural reference streams and assessed their stream environments. Stream Visual Assessment Protocol(SVAP) developed by United States Department of Agriculture (USDA) Natural Resources Conservation Services (NRCS) was used to assess 10 different categories of stream environment including channel condition, hydrological status, riparian vegetation, water appearance, and flow diversity. Each of ten categories was scored from 1 to 10 and averaged to determine ecological status into one of four classification levels, ie, excellent, good, fair, and poor. Overall average score for the select streams was 6.9 which falls into "fair" classification. Among the environmental categories, the stream stability was scored the best while the barrier to fish migration was the worst. In riparian usage perspective, most of project streams lacked of stream ecological consideration by overly constructing waterfront facilities. It was recommended that the prior consideration in the stream restoration should be given to stream ecological health, especially to fish migration improvement and prudent design of waterfront facilities. Restoring stream hydrology(e.g., environmental or ecological flow) also needs to be premise of stream restoration since flowing water is part of definition of stream.
