No. Dogs and other pets are not allowed in the Los Vaqueros Watershed. This protects the multitude of small animals, some of which are endangered, that live in this protected watershed environment. Many of these endangered animals are easily disrupted by both the presence and scent of dogs. This rule also protects public safety and water quality. The Round Valley Regional Preserve, which borders Los Vaqueros, is also under this rule. At Morgan Territory, which is located above the Marina, dogs are allowed.
