Rivers & Streams Quick Reads

Meet Joseph Batom, a Water Quality and Wetland Monitoring intern working at the Golden Gate National Recreation Area through Environment for the Americas!

"While I was in college, I didn't want to go back home for the summer to work at the local grocery. I applied for a bunch of environmental internships and got a fisheries internship in Colorado. I had no prior experience or any interest in fish, but I thought 'why not?' I went out there, learned a lot, and had an amazing time. After the fisheries internship, I knew I wanted to continue to work in natural sciences."

Meet Darren Fong, aquatic ecologist for Golden Gate National Recreation Area and lead scientist for the SFAN streamflow monitoring program. Discover how Darren's fascination with aquatic life and freshwater ecosystems began and learn how he got to be where he is today.

Water quality is an indicator of the condition of aquatic habitat and is also an important indicator of the overall health of watersheds. In partnership with the Presidio Trust, National Park Service Inventory and Monitoring Program staff conduct monthly water quality monitoring at 16 sites in the Presidio to determine long-term trends in water quality parameters. These include water temperature, pH, dissolved oxygen, nitrate (as nitrogen), phosphate, and coliform bacteria.

Freshwater quality affects people’s enjoyment of San Francisco Bay Area national park resources, and plays a direct role in the health of aquatic habitats. In 2006, the National Park Service began monitoring freshwater quality under a long-term monitoring plan developed for Golden Gate National Recreation Area, John Muir National Historic Site, Muir Woods National Monument, Pinnacles National Park, and Point Reyes National Seashore.

The amount of water flowing in a stream, or streamflow, is among the most useful factors available for understanding watershed and stream health. The San Francisco Bay Area Network Inventory and Monitoring Program and its partners monitor streamflow in selected streams at Golden Gate National Recreation Area, Pinnacles National Park, Point Reyes National Seashore, and the Presidio of San Francisco.
