The damage to the wetlands that were once present there had persisted for so long that officials working on the project had to bring in historians just to figure out where the old marshes used to be.<\/p>\n<p>That was around 2010, during which year a design for the project was completed and implemented. It created open water channels, emergent tidal marsh lands and floodplain habitats to sustain water fluctuations. All of this was done in an effort to help important wildlife living in the delta as well as fish species like Chinook salmon and delta smelt.<\/p>\n<p>But beyond just putting new marshes in place, it\u2019s important for delta restoration managers to verify that their efforts made a difference. Doing that involves monitoring conditions around the site to see how its habitats and water quality have improved.<\/p>\n<p>Crews at the U.S. Geological Survey\u2019s California Water Science Center oversee such a network that encompasses the delta. It relies on a number of continuous monitoring stations that gather data on the area\u2019s water quality, and has been collecting data for the last few years. In 2014, the USGS added a NexSens CB-950 Data Buoy to complement that effort.<\/p>\n<p>\u201cThe buoy is located at the mouth of Liberty Island in the Cache Slough Complex in the northern portion of the Sacramento-San Joaquin Delta,\u201d said Scott Nagel, hydrologic technician with the U.S. Geological Survey. It is equipped with several sensors measuring parameters including water temperature, conductivity, pH, dissolved oxygen, turbidity, fluorescent dissolved organic matter and chlorophyll-a.<\/p>\n<div id=\"attachment_24937\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-24937\" class=\"size-full wp-image-24937\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2016\/03\/liberty_sensors.jpg\" alt=\"Sensor package, including a YSI EXO water quality sonde, mounted to the buoy\u2019s instrument cage.

These include Thomas Johnston, student intern; Renee Runyon, hydrologic technician; and Kyle Nakatsuka, a field assistant.<\/p>\n<p>Other buoys in the network, two NexSens CB-500s, help to add to the understanding of the impacts that conditions and nutrients have on aquatic life in the delta and the overall quality of their habitats. Too much turbidity, for example, could influence light penetration in the water that aquatic plants use. Or high algae levels can bring about low-oxygen conditions for fish.<\/p>\n<p>But data aren\u2019t just upping knowledge for folks at the USGS. Nagel says that the data gathered are also shared with concerned stakeholders and make their way into print for wider distribution. The data from the buoy are sampled every 15 minutes and telemetered. Anyone can see the measurements available here: LIB buoy data.<\/p>\n<p>\u201cWe have had a buoy at this site for almost three years and have been constantly pleased at the data quality,\u201d said Nagel. \u201cSome results are currently in press and others are being compiled into a data report, so keep an eye out for them.\u201d<\/p>\n<p><em><span style=\"color: #808080;\">Top image:\u00a0NexSens CB-950 Data Buoy deployed near Liberty Island in the California Delta.
