The Case Inlet/Pickering Passage Subbasin covers about 97 square miles (including the area of inlets, not including the small streams draining to Hood Canal. These streams are officially part of WRIA 14, but they will not be addressed in this report. They will be included in the WRIA 16 limiting factors report as requested by the Hood Canal Coordinating Council).

Sherwood Creek is the largest stream system in WRIA 14, containing 18.3 miles of channel. The creek empties into Case Inlet at North Bay near the town of Allyn. Average flow is 15 to 25 cfs. Outlet flows from Mason and Prickett Lakes are the origin of the stream. Shumocher Creek and four tributaries provide inlet flow for Mason Lake. Trask Lake (18 acres) provides flow to the first tributary of Shumocher Creek at RM 13 (immediately above the inlet to Mason Lake). Mason Lake covers 977 acres and is four miles long. Prickett Lake is 3/4 mile long and covers 73 acres. A small mill pond is located at about RM 1.0 on Sherwood Creek. Dense stands of second growth conifers and cultivated Christmas trees dominate the watershed above RM 3. The lower end of Sherwood Creek flows through steep ravines vegetated by alder, maple, and ferns (Washington Department of Fisheries 1975).
