After sustained temperatures over 100 degrees last week, the shallow water and lack of oxygen in west Boise's Redwood Pond caused bass, bluegill and other species to die. At its deepest point, the pond is only about 14 feet.

More mosquitoes, carrying the potentially deadly West Nile Virus, have popped up in traps in Canyon County. Two weeks ago, the disease was found between Parma and Notus. Now, mosquitoes at the Roswell Marsh near Parma have tested positive.

Ed Burnett, with the Canyon County Mosquito Abatement District, says they found hundreds of Tule mosquitoes in a trap on the marsh. Tules – which carry the virus – are rare for this area. Burnett says they’ve multiplied because of recent hot weather.

Sunday broke some records for high temperatures, but the heat didn’t break Idaho Power’s record for peak demand. That’s even though the company is seeing tremendous demand on the system.

Sunday, the company used 3,292 megawatts of power to keep irrigators pumping and air conditioners on. But spokeswoman Lynette Standley says the system record — set July 2 — 2013, is 3,407 megawatts.

Idaho Power expects to use more power Monday than Sunday. Standley says the projection is over 3,300 megawatts. That compares to an average use of less than 2,000 megawatts.

Idaho Power sees the highest demand for electricity in the summer when people crank up their air conditioners. And with a long stretch of very hot weather in store, that demand is expected to be very high.

The utility that powers most of southwest Idaho and eastern Oregon set a new record for energy consumption just two years ago in July. Idaho Power spokesman Brad Bowlin says that record could be surpassed soon.

Sunday saw record high temperatures for much of southwest Idaho and eastern Oregon. In Boise it got to 91 degrees. That unusual heat brings a chance of thunderstorms for much of this week. But the temperature won’t stay at record levels long. Later in the week highs will likely drop to the 50s. 

Jay Briendenbach, the Warning Coordination Meteorologist at NOAA's National Weather Service Office in Boise, says a system of high pressure ridges and troughs is circulating hot and cold air around the country quickly.
