Lake Erie Volunteer Science Network: Building Trust in Citizen Science Programs
Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. 
 
[caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. 
 
Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit.

Lightweight and easy to use, the SonTek CastAway offers a convenient 3-in-1 solution for measuring conductivity, temperature, and depth profiles. At a 5 Hz sampling rate, the CastAway is designed for up to 1 m/s free-fall through the water column. 
 
 With fast response and accurate conductivity, temperature, and depth measurements, the CastAway is ideal for thermocline and halocline profiling. The unit also reports salinity and speed of sound.
