In 2020, over 4,000 plants from 12 different species were planted between Port Culver and Lower Eastfoot to increase native plant diversity while simultaneously combating invasive species at each basin. The plants were sourced from Tree of Life nursery and were planted by the District’s landscape contractor.
The primary surrounding land uses are agricultural. It went online in 2008.

The site maintains below average biological values, as it is receives so little dry weather flows of water. The surrounding land uses are primarily agriculture, however, across Portola Parkway dense urban development is present. The site has been replanted with wetland vegetation, as some of the original vegetation did not survive due to dry conditions.
