YAKIMA, Wash.-- Yakima's wastewater division might need more money to continue its salmon restoration project along the Yakima River. The same project involves extending the greenway. The department says the grant money it has won't be enough. So now, it applied for a grant from the Department of Ecology. The department's putting used Christmas trees into the river to protect salmon. Now, it needs the money to buy more. A decision on the grant should come next month.
