Conservation in Action: Boulder Creek

Boulder Creek

Boulder Creek is an amazing ecosystem with much history!

Site Background and History
In 2012, we were contacted by a local fish conservation group, the San Diego Fly Fishers, about the recent finding that a small population of wild rainbow trout were surviving on Boulder Creek within the San Diego River Watershed. We were asked to get involved with an effort to support the trout, restore the creek and develop a program to survey and monitor how the trout are doing. They also asked us to partner with them to conserve privately owned property that contained this portion of the Creek.

We learned about a key piece of property that was for sale, and when we did a tour we saw 11 rainbow trout. Wow! We knew this property had to be protected. It was a perfect place to launch this exciting conservation project and partnership. A deal was soon struck with the owner, and we were given 75 days to raise the funds needed to acquire the property. Thanks to the support of more than 100 donors, we raised sufficient funds to conserve this small but critical 2.35 acre property. We also received incredible support from Mesa Rim Climbing & Fitness Center, who helped us secure a 3 year loan for the $85,000 of the funding required. During the acquisition, we learned that the property immediately upstream was on the market. This 11 acre property has a drier section of the creek which has been disturbed by fire and subsequent erosion. It was a critical piece where the creek could be restored to support the fish and other wildlife. Thanks to more than 200 donors, we raised more than $20,000. We borrowed $35,000 from two of our supporters and completed the acquisition of this second property in February of 2013. Thanks to our supporters we have paid off both loans.

December 2018 Update
We just visited the property and the stream is beautiful! We are working to restore trees and other plants along Boulder Creek. Last month we wrapped up a multiyear grant which included removing non-native and diseased plants and planting new ones. We also added some interpretive signs and other elements, created a small plant nursery, added a real-time water monitoring station and new wildlife cameras.

As funding is available we will continue caring for the restored oak woodlands and riparian stream. If you are interested in volunteering or donating to this project, please let us know. Thanks.

We are also working on other enhancements and cleaning up the property. The outdoor seating area and Field Station are in! We are beginning a new project to learn more about bats which are in an old mine on the property.

The site is available for education programs and other activities. If you are interested in volunteering or learning more, please contact the River Park Foundation office at 619-297-7380.
