A key mission of the Hi-Lakers is to provide lake survey reports for better high lakes fishery management. Surveys are generally submitted online. Some of the most valuable data for biologists and fishery managers may not be obvious. The following components deserve special attention and should be included whenever possible. 
Access changes – Report any changes to access trails or roads that may impact visitor traffic, such as closures/blockages, detours/bypasses, new trails created, etc. This matters because fish mortality is one of the most important considerations when deciding how many fish to stock, and change in the number of anglers visiting a lake may necessitate a change in management. 
Evidence of overuse by visitors – Report damage to vegetation around the lake and along the trails, trash left behind, etc. Record the number and condition of campsites and fire rings. This information is another indicator of changes in use patterns and angling which could necessitate management changes. 
Changes in trout reproduction status – Provide accurate measurements of ALL fish caught whenever possible. It’s also helpful to include approximate size of fish observed cruising, as well as fish reported caught by other anglers not in your party. Biologists and fishery management can reference this information against the stocking data to indicate the presence of natural reproduction. 
Verification of survival of recent fry plants – Report any fish you find that are 1-2” long. Check inlets, outlets, shorelines, shallows, and around cover. Aside from confirming the survival of recent fry plants, this is also important because it reveals the presence of fry that was stocked illegally.
Results from experiments – Biologists are especially keen to receive data for ongoing projects, such as the tiger trout experiments at Forest and Lonesome Lakes in Pierce County, and the tiger musky experiment at the Anderson Lakes in Lewis County. 

Make use of the General Comments field – So where do you enter this data? When submitting your survey online, any data mentioned above that does not fit neatly into a corresponding field should be entered under General Comments (step 5 of the survey data entry process). This is one of the most important survey data fields, and one often skipped. Members are encouraged to note everything they think could be significant. 


Learn more – For a comprehensive understanding of the survey process and all related data fields refer to the Volunteered High Lake Surveys Field Data Collection Guidelines in the member’s only section (login required). This 20-page document was carefully prepared by former WDFW Fishery Management Biologist and Hi-Laker, Bob Pfeifer. You can also find a brief description of common data fields on the printable High Lakes Fishing Report form.
