Hilo Bay Water Circulation and Water Quality Study -APRIL 2009
In October 2004, the County of Hawaii requested planning assistance from the U.S. Army Corps of Engineers, Honolulu District to evaluate water circulation and apparent degraded water quality within Hilo Bay and identify potential solutions. In response, this study was initiated to collect field data and implement numerical modeling of circulation, wave transformation, and identify alternatives to improve water quality in Hilo Bay. The study investigates the feasibility of modifying the Hilo Harbor breakwater to increase water circulation within Hilo Harbor. Increased circulation could potentially provide corresponding improvements in water quality within the bay thereby providing a more suitable environment for recreation and a greater aesthetic enjoyment of the area.
Water Quality Final Report - July 2008
The HBWAG conducted a water quality sampling program on several rivers and streams within the Hilo Bay watershed in 2008. The intent of the project was to assess the present conditions and gather data to help build a baseline for future comparisons. Project funding was provided by a grant from the Hawaii Coastal Zone Management Program.
Proposal for Stream Water Quality Monitoring - 2008
Proposal submitted to CZM to perform stream sampling around Hilo Bay area in 2008.
Hilo Bay Watershed-Based Restoration Plan, October 2005
Several segments of coastal and inland waters in the Hilo Bay watershed have been on the 303d list of impaired for several years, and Bay waters have been known to exceed state water quality standards since at least the late 1970s. This Watershed Restoration Plan identifies the key threats to the Hilo Bay water quality, and recommends that several BMPs and Demonstration Projects be considered for the Hilo Bay Watershed.
Hilo Bay Watershed Project Public Input Report, May 2004
Hilo Bay and its tributaries do not comply with all State water quality standards and were therefore put on the U.S. Environmental Protection Agency (EPA) 303(d) list of impaired waterbodies. EPA grant funds were obtained to complete the initial step of the EPA program to bring waters into compliance with standards. This report documents the public input, describes the public input process and analysis, and states the conclusions, including the watershed restoration priorities.
