Objective(s): The objectives of the single site visit in 2007 are as follows: (1) to re-install instruments at the 4 existing hydrostations, so that data will be recorded automatically during the summer season; Tyhee personnel will remove the instruments (a datalogger and pressure transducer for each station location) at the end of the season, before freezeup; (2) download data from the existing weather station, change out the data-storage module and perform any required maintenance to the station or its instruments; and (3) re-install Tyhee's existing evaporation pan and train site personnel in how to take + record measurements at the pan (measurements are taken daily) and then how to dismantle the pan setup at the end of the season.

Project Description: The objectives of the single site visit in 2007 are as follows: (1) to re-install instruments at the 4 existing hydrostations, so that data will be recorded automatically during the summer season; Tyhee personnel will remove the instruments (a datalogger and pressure transducer for each station location) at the end of the season, before freezeup; (2) download data from the existing weather station, change out the data-storage module and perform any required maintenance to the station or its instruments; and (3) re-install Tyhee's existing evaporation pan and train site personnel in how to take + record measurements at the pan (measurements are taken daily) and then how to dismantle the pan setup at the end of the season. Continuance of data collection at the project's existing 4 hydrostations and 1 weather station is required to obtain sufficient baseline to enable Tyhee's Yellowknife Gold Project to progress toward development and the permitting and licensing which such development would require. The objectives of the 3-day site visit in June 2007 are: (1) to install dataloggers and pressure transducers at the 4 hydrostations, so that data on waterflow can be recorded automatically over the summer season; (2) to download data from the site weather station (this data is recorded automatically between yearly visits), carry out any required maintenance to the station or instruments, and (3) set up the evaporation pan, which is sited next to the weather station, and train Tyhee personnel in how to take and record the daily readings. The following activities are planned for this project: Transportation: EBA field scientist and assistant will travel to the site by fixed wing, and visit the 4 hydrostations by helicopter or boat, and visit the weather station (which is near camp) on foot. Equipment to be re-installed at each hydrostation consists of a datalogger (to record) and a pressure transducer (to detect fluid pressure + produce a signal related to the pressure it has detected). The purpose of the hydrostations is to develop a time history of waterflow from waterbodies in the project area. The weather station already has instruments installed to collect site-specific weather data, such as air speed + direction, air temperature and precipitation; however, the module which automatically stores data needs to be removed and a new one put in place, the collected data downloaded and routine maintenance performed. Finally, the existing evaporation pan on site will be reestablished, so that data on evaporation rates can be recorded over the summer season; in meteorology, an evaporation pan is used to determine, through observations, the quantity of water that evaporates into the atmosphere at a given location. There is no new technology associated with the site activities. Letters have been e-mailed or posted to neighbouring communities, explaining the project, providing sketch-maps and photos of the hydrostations and weather station, and soliciting interest in participating in the 3-day fieldwork. After the field season, a summary of results will be provided to communities, as well as a complete final report to those groups who wish copies. Fieldwork will be conducted from June 26 to July 31, 2007 near the Tyhee's Yellowknife Gold Project (within these co-ordinates: 63° 13' 59.76" N - 13° 45' 00" W and 63° 14' 59.87" N - 113° 46' 59.88" W).
