TryMarine Grant

The Reservoir Fish Habitat Partnership (RFHP) is seeking candidate pilot sites for evaluating two water quality treatment technologies—TryMarine and Oase Water Technology—in small urban fishing lakes (1–3 acres).
Urban fishing lakes are important community resources, providing accessible angling opportunities and supporting local outdoor recreation. Many of these lakes experience nutrient‑driven water quality impairments such as algal blooms, low dissolved oxygen, and reduced water clarity. These issues degrade fish habitat and diminish angler satisfaction.
This pilot initiative aims to identify lakes where these technologies can be tested to determine their effectiveness, feasibility, and potential for broader application across the RFHP network.
Water Quality & Habitat Objectives
Reduce nutrient concentrations (total phosphorus, total nitrogen).Improve water clarity and reduce turbidity.Reduce harmful algal blooms (HABs).Increase dissolved oxygen stability to support sportfish populations.Improve habitat conditions for stocked and naturally occurring fish species.Reduce internal nutrient loading from sediments.
RFHP Program Objectives
Demonstrate scalable tools for improving fish habitat in small urban lakes.Support community‑based fisheries enhancement.Provide case studies and data for future RFHP guidance.Strengthen partnerships among agencies, municipalities, NGOs, and angling groups.
