| 説明 | Reclamation hosted a group of middle school kids from the Douglas City School in Douglas City, CA for a science field day. The group of 7th and 8th graders used high-tech equipment along with good old-fashioned field skills to learn how projects are designed and constructed and how to monitor improvements in fish and aquatic habitat. |
