Aquatic Site Marker
Each site has up to eight groundwater wells outfitted with sensors that measure high temporal resolution groundwater elevation (pressure transducer-based), temperature, and specific conductance. Met. Station
A met. station is located on the shore of most aqutic sites and collects data comparable with flux tower measurements at terrestrial sites. Lake and wadeable rivers also have an above water met. station on buoy. These data are unique with different sensors and data frequencies due to power and data storage constraints. Sensor Station
Wadeable streams have a sensor station near the top of the reach and the bottom of the reach; non-wadeable rivers have a sensor station on a buoy and one near the bank; Lakes have an inlet sensor station, an outlet sensor station and a sensor station on a buoy. Data collection varies by type of sensor station. Click on sensor station on the map to learn more. Staff gauge/camera
The staff gauge measures gauge height, in meters, measured at lakes, wadeable rivers and non-wadeable streams. A phenocam is installed near most gauges. It collects RGB and IR images of the lake, river, or stream vegetation, stream surface, and stream gauge every 15 minutes. Observational Sampling

Construction Status for this Site
This field site is located in the
Nature Conservancy's Oka’ Yanahli Preserve, which protects nearly 3,600 acres of native prairie and is along one mile of the Blue River in Southern Oklahoma.
According to the Nature Conservancy, "the Blue River basin encompasses a variety of freshwater ecosystems, from rolling limestone prairies to oak forests in granite canyons to bottomland hardwood forests. An astonishing array of plant and animal species depend on a healthy, sustainable Blue River basin, including the Blue River subspecies of orangebelly darter, orangethroat darter and least darter; ringed crayfish; rabbitsfoot mussel; chatterbox orchid; bald eagle, prothotary warbler and dozens of species of migrating birds. Seaside alder, found only in three widely disjunct parts of the United States—and arguably the rarest tree in North America—is more abundant on this river than anywhere else.
It is also a critical source of water for human needs. In addition to providing for agricultural needs, the river sustains the city of Durant. Ranked the fastest growing rural city in Oklahoma, Durant is home to Southeastern Oklahoma State University and the headquarters of the Choctaw Na!on of Oklahoma.
Oka’ Yanahli [oh-kuh yuh-naw-lee] means 'flowing water' in Chickasaw." Their conservation efforts include restoration and protection of the Blue river to improve flow patterns and increase the sustainablity of the wildlands that surround the river.
Please note that although this field site is geographically located in D08 Ozarks complex, the vegetation and stream characteristics of BLUE most closely align with the characteristics of D11 Southern Plains - therefore this site is part of NEON's D11.

Data Collection Types Airborne Remote Sensing Surveys
Remote sensing surveys of this site collect lidar, spectrometer and high resolution RGB camera data.
This site has one meteorological station located in the riparian area of the stream that is outfitted with the a subset of the same sensors used at terrestrial sites. Measurements include wind speed and direction, air temperature, barometric pressure, relative humidity, shortwave radiation, and PAR.
This site has one phenocam near the stream.
Surface Water Sensor Stations
This site has one near bank sensor station and one buoy-mounted sensor station. The automated instrument measurements at the buoy site are: PAR at water surface, PAR below water surface, temperature at specific depth in surface water, water quality (specific conductivity, chlorophyll a, dissolved oxygen content, pH, turbidity, and fDOM), and nitrate. Near the bank, the automated instrument measurements are: PAR below water surface, elevation of surface water, and temperature in surface water.
Eight groundwater wells throughout the site collect specific conductivity, water tempertaure, and elevation of groundwater.
