The dog days of summer are right around the corner, but it might be best to leave your pooch at home on warm days. Hiking in warm temperatures can be dangerous for your dog. You can use this chart as a guide to determine whether the temperature/humidity are too high for your dog to exercise outdoors.

May is Water Awareness Month. Water is vital to all of us, including EFRR residents. We are grateful for Olivenhain Reservoir, which provides water for fish, coyotes, bobcats, deer, and more. It can also provide San Diego with up to 7.8 billion gallons of water during an emergency.

This past weekend, in celebration of Earth Day, Park Rangers and volunteers partnered with EFRR for the I Love A Clean San Diego Creek to Bay Cleanup. Hundreds of pounds of trash and debris were removed from Escondido Creek and the surrounding area. If left in place, this debris can harm sensitive riparian habitat and eventually reach the ocean. Thank you to all our volunteers. The watershed is a little cleaner because of you!

Happy Earth Day! Show your love of the Earth by joining in our annual creek cleanup with I Love A Clean San Diego. It will be held on April 25, from 9:00 a.m. to 12:00 p.m. Thousands of volunteers across San Diego County will come together on Saturday to give back to their communities by removing litter from local waterways. At EFRR, removing litter and debris from in and around Escondido Creek helps protect our sensitive riparian habitat for EFRR’s residents.
