The In-Situ Level TROLL 500 Water Level Logger contains everything needed for water level measurement and logging - level and temperature sensors, data logger, and internal power - all in a 18.3mm (0.72 in) diameter housing with a lot of exciting capabilities. The instrument is built entirely from rugged titanium with TIG-welded seals, eliminating the potential for flooding from faulty O-ring seals.
The In-Situ Level TROLL 500 Water Level Logger offers Twist-Lock connectors that provide a secure connection between the sensor and cable. The Twist-Lock connectors are also extendable, allowing the user to easily lengthen the cable without purchasing a complete replacement assembly. In-Situ's new ultra low-power system guarantees 5 years or 2 million readings. For added flexibility, the instrument can also be powered externally. System integration is easy with built-in RS-485 Modbus, SDI-12, and 4-20mA communication output capability.

Moving levees can help recharge groundwater aquifers in California
Groundwater typically makes up more than 30 percent of California’s annual water usage, according to the state’s Department of Water Resources. But during times like the current prolonged drought, groundwater becomes more important, meeting 46 percent of the state’s annual needs. With the rising dependence on groundwater in dry times, scientists have begun looking for ways to fill up depleted aquifers and keep flush those still filled with water. The goals have led to new approaches, like one coming out of a research project led by scientists at the Universities of California, Davis and Merced, that looked at structures somewhat overlooked in times of low water levels: flood levees. The study took place along the Cosumnes River, the last major undammed river in California.

Watershed groups handing tech to volunteers for better citizen monitoring
Watershed protection groups across the country are collecting water quality data on waterways that might otherwise miss out on monitoring entirely. Some have found that, despite small staffs, they can compile more high-quality data by putting water quality sensors and other professional scientific instruments in the hands of volunteers. For organizations like the Santa Barbara Channelkeeper, the reasoning for equipping volunteers with electronic handheld meters is clear: "We really want the data that we're collecting to be utilized," said Ben Pitterle, director of the group's watershed and marine program.

Report: Lower Great Lakes water levels could hurt Canadian economy
A report released by the Mowat Centre and the Council of the Great Lakes Region finds that lower water levels in the Great Lakes could cost the Canadian economy $10 billion over the next 15 years, according to The Barrie Examiner . The report was funded by the Ontario Government and Georgian Bay Forever, an environmental group. Considering the worst consequences of lower water levels, the report forecasts losses in commercial shipping, tourism and hydroelectric generation. Declines in waterfront property value are also predicted. The largest impacts are likely to be felt in the recreational boating and fishing sector, and report authors predict losses to the tune of $6.65 billion through 2030.
