One private landowner owns the majority of the Gull Harbor Estuary with the remainder of the watershed divided into smaller residential lots.

Adams Creek and three other small, unnamed creeks drain into Gull Harbor, a substantial 30-acre protected estuary habitat on Budd Inlet. The intact estuary represents one of the only remaining contiguous unarmored shoreline reaches in all of Budd Inlet. Adams Creek has two partial (33% passable) barriers at the road crossings on Boston Harbor Rd. The stream lacks key pieces of LWD, though the riparian corridor is functioning with regards to stream bank conditions. Adams Creek runs through a wetland complex, providing rearing habitat for juvenile coho. Tributary 13.0019 has a complete blockage at river mile 0.2 as it runs through agricultural pasturelands, with little to no riparian buffer. Tributary 13.0020 has a full and a partial (33% passable) barrier towards the mouth, severely limiting access to one mile of intact habitat. The riparian cover consists of a mixture of conifers and deciduous vegetation, with off-channel habitat for rearing. Current sampling of the benthic invertebrates is on going, documenting the health of this tributary. Tributary 13.0021 has a full and a partial (33% passable) blockage at RM 0.5. The riparian corridor is functioning, with mixed riparian buffers and instream LWD. Adams Creek and the other tributaries to Gull Harbor face serious development pressures as one of Olympia's most highly desired residential areas. Several conservation easements are in place to protect this vulnerable nearshore habitat.
