The habitat that fish live in is directly related to weather. If the weather is cool and rainy, then rivers and streams flow well and remain cool. If weather is hot and dry, then rivers without cover tend to be the same. What is cover? Well cover can be any structure or thing that provides protection, in this case for the fish. It may be shade from the hot sun or a deep pool to ward off bird predation. Knowing this, one can assume fish are either going to venture into deep pools or migrate up or down the stream to areas with more shade or to cooler tributary confluences. If the fish don’t have that freedom to move, then they have to make do during the thermal stress event. If they don’t, then they die. This is what happens during the late spring/early summer when the air temperature warms up rapidly and fish don’t have time to acclimate to their new environment. We call such an event a fish kill.
So with that harsh lesson, I would recommend letting things cool off before you head out fishing for trout. They are already stressed and most likely spending their energy seeking cool refuge. Try focusing on warmwater species like northern pike, large- and smallmouth bass and yellow perch. Target vegetation beds and log structures. They will be where the fish are hiding.
I would try Cedar Pond, Martin Meadow, Forest Lake, Pontook and Moore Reservoirs. If you would like to fish a river, check out the Connecticut. It remains cool even in hot weather. These spots also provide some swimming opportunities if you would like to take a dip yourself. -- Dianne Timmins, Fisheries Biologist
LAKES REGION/WHITE MOUNTAINS:
The smelt survey is on-going; we should wrap up Winnipesaukee in a couple nights. We are finding smelt pretty much everywhere. Last night, we worked out in the "Broads" between the Gilford and Tuftonboro shores. It was very encouraging to see a good number of older-aged smelt in the trawl sample. Only one month left to salmon season...get out there and enjoy, I'm sure we will have a long winter! – Don Miller, Regional Fisheries Biologist
SEACOAST NEW HAMPSHIRE:
The changing seas also stirred up some bluefish this weekend. The headboat companies reported a banner day, and I talked with a few anglers on Saturday who had caught them down in the Hampton area as well, so it wasn’t just the professionals that were able to find them! One important tip I got from successful striper fishermen was to get out there early. When I say early, I mean get out before sunrise. Take your time and work your way seaward; stripers' location will move with the tide and the time of day. Poke around in all of the coves, eddies, and anywhere you find a rock pile for them to lurk behind. Things seem to be going well at the moment so let’s all hope that Earl doesn’t cause things to do a 180 on us! – Rebecca Heuss, Marine Biologist
SOUTHEAST N.H./MERRIMACK VALLEY:
While there is not much we can do about the weather, there are things we can do to help maintain healthy summer flows in our rivers. Water withdrawals for irrigation, drinking water, and other uses can impact aquatic species when too much water is removed during periods of low flow. The Ipswich River, in Massachusetts, has actually been known to dry up in the summer due to the over use of water. There is a need to support emerging legislation in New Hampshire that will protect instream flows.
At the local level, you can support changes in zoning that protect riparian zones along rivers and streams, reduce the total amount of impervious surfaces like large parking lots, and encourage stormwater management that allows water to filter back into the ground instead of running directly into a river or stream. These practices will help precipitation absorb into the ground and restore groundwater, which ultimately maintains summer river flows, rather than flow as runoff directly into rivers and streams, which worsens flooding.
Unlike the more developed areas of southern New England, where instream flows are already a chronic problem, New Hampshire has a chance to be proactive on this issue. If we take steps to protect instream flows now, then we can maintain healthy water levels in our rivers and streams and help prevent that prime spring fishing season from shrinking for future generations.

All captured bass are identified as to species, weighed, measured, and released. Scales are taken on larger fish in order to later age the fish to determine if it was a young-of-the-year or an age-1. The objectives of these surveys are to determine: 1) fish size; 2) relative abundance (# fish captured per hour of sampling); 3) to examine relative abundance by species among years; 4) to compare size by species among years; and 5) to compare size between species among years.
These surveys are important because black bass populations in the state are managed solely by natural reproduction, and size of young-of-the-year bass during their first fall can be an important factor in their over-winter survival. Monitoring young-of-the-year bass size and catch rates allows us to gauge potential year-class strength and can provide for early detection of any needed management options. – Gabe Gries, Regional Fisheries Biologist
