Another storm system will pass through the Central Valley on Tuesday, bringing light, scattered showers. Rain will start developing around midnight on Tuesday and will continue into the afternoon. The bulk of the system will pass through between 7 a.m. and noon, said Scott Borgioli, WeatherAg chief meteorologist. Scattered showers will bring less than a quarter-inch of rain. Tuesday’s high temperatures upper 60s, but a warming trend could push the mercury above 85 this weekend.

Water transfers are an important way to share a limited resource, especially to help fish and habitats that were historically left with scraps when water rights were parceled out around the West. The water for such transfers usually comes from farmers, who free up water through some kind of conservation measure. By transferring the saved water, a farmer can help imperiled fish and make some money. Such arrangements are especially important on the Colorado River, which is oversubscribed to serve human demands and also feeds a vast international ecosystem.

According to informal surveys following the February evacuations ordered in response to the Oroville Dam crisis, a large segment of the local population said they stayed at home rather than leave for higher ground. From the looks of an inundation map created by graduate students at the UC Irvine Department of Civil and Environmental Engineering, those residents who stayed behind might have wanted to rethink things. The recent study conducted by the graduate program forecasts the potential destruction that could have followed a complete failure of the emergency spillway at Lake Oroville.

Carrizo Plain National Monument is a place of extremes. The grassland, the largest of its kind in California, stretches across over 250,000 acres of unforgiving wilderness. Caliente Mountain and the Temblor range border the plain, while the San Andreas Fault cuts it down the middle. Surface fractures are visible across the dry landscape. The species that call home to the Carrizo Plain don’t just survive, but thrive in its acute conditions.
